North America was originally named Vinland by Leif Erikson but was later called North America by Amerigo Vespucci. It formed as a continent over 1 billion years ago on the North American tectonic plate and has many unique landforms like mountain ranges as well as plants and animals not found elsewhere such as porcupines, axolotls, and sequoia trees. Shifting of continents over time caused climate and vegetation differences across the region.

The Tertiary period saw a gradual worldwide cooling of climate from tropical temperatures in the Paleocene to more moderate temperatures. Tectonic plate movement was ongoing, including the complete breakup of Gondwana and the collision of India with Eurasia. Life during the Tertiary included modern birds beginning to emerge, the rise of placental mammals, snakes, teleost fish and pollinating insects, as well as the existence of grasses and flowering plants, but did not yet include human beings.

The Galapagos Islands are located off the coast of Ecuador in South America and were formed by volcanic activity millions of years ago. They were explored by Father Tomas Berlanga, John Cook, and Charles Darwin. The islands are known for their giant tortoises that can weigh 500 pounds and live over 100 years.

The Natives migrated from Asia to North America over 10,000 years ago via a natural ice bridge between Siberia and Alaska. They came for several key reasons: to find new sources of food as survival depended on it; to seek a better climate as the ice age was changing conditions; and to start new lives with opportunities like new religions, communities, land ownership, or escape difficult existing situations. This migration populated the Western Hemisphere and ultimately led to the establishment of civilizations and cultures across North America.

Plate Tectonics is the driving force of geologic structures th.docx
Plate Tectonics is the driving force of geologic structures that shape the world that we live in. The
first indication that continents might have been linked physically took place as soon as there was
mapping. It was known by the sixteenth and seventeenth century that the continents fitted together like
pieces of a puzzle. This and other proofs listed below lead to the concept of continental drift, that the
large continents had once been linked together. The scale movements of continents across the across
the surface of the planet was mind boggling.
By the close of the nineteenth century the geologist Edward Suess postulated that the southern
continents were joined together. This was from evidence seen by fossil animal distribution. Ancient life
forms have ranges just as modern animals. Tigers are found in India and Siberia, not in North America.
These ancient animals couldn’t get from South America to Africa, from Antarctica to Australia to India.
There were rock layers both sedimentary and igneous that were continuous on all of the five continents.
He christened this large continent Gondwanaland.
In 1915 Alfred Wegener wrote a book on continental drift. He proposed another super continent
called Pangaea. This continent included all of the modern continents. His mechanism for the movement
of the continents was that the continents moved through ocean crust, drifting until they joined then
breaking apart again. Wegener and others argued for their evidence pointing out rock similarities
type, similarities in rock trends and ages using all of the information gathered from Steno's laws and
fossil assemblages. They also showed that certain distant continents had similar plants and animals that
entered a different evolutionary path after the continents separated. An example of this is the fresh
water fish the Arowana found in both South America and Australia. Another example of this is the large
amount of marsupial
fossils found in South
America and Australia.
Placental mammals
were the dominant
mammalian life forms
in Eurasia, North
America and Africa.
Only in South America
and Australia were
marsupial fossils
dominated. It wasn't
until 3 million years ago
North and South
America joined
allowing placental
mammals to gain
dominance in South America. Despite this evidence Wegener and his followers mechanism for
continental movement was badly flawed. They proposed that the tidal forces from the Sun and Moon
like the tides in the ocean. This force is much too weak to move a continent so the theory was rejected.
Fossil plants and animal distribution on southern continents
In 1928 a geologist Arthur Holmes proposed the convection currents split the continents and that
these currents were in the mantel. Remember the knowledge of a mantel was already known at this
time. Ironically this was a mechanism had been proposed by Benjamin Franklin in 1782. Many

Continental drift
1) Early scientists like Bacon and Snider-Pellegrini noticed similarities between continents like Africa and South America, but it was Wegener who first proposed the theory of continental drift in 1915.
2) Evidence for continental drift includes matching coastlines, similarities in fossils found on different continents, matching rock types along coastlines, and geological features lining up across continents.
3) In the mid-20th century, discoveries of seafloor spreading and plate tectonics provided the mechanism of plate tectonics to explain continental drift, with ocean floors being created at mid-ocean ridges and spreading outward over time.
Continental Drift
The document discusses evidence that supports the theory of continental drift proposed by Alfred Wegener in 1915. Some of the key evidence includes:
1) The fit of the continents' coastlines and continental shelves suggests the continents were once joined together.
2) Glacial deposits and fossils found in regions that are now tropical provide evidence these areas were once farther from the equator when the continents were in different positions.
3) Certain fossil types found across continents that are now separated by oceans could not have crossed the oceans, indicating the land was once joined.
Plate tectonics
The document discusses plate tectonics and the evidence supporting continental drift. It describes how Wegener first proposed the hypothesis of continental drift in 1912 based on observations that the continents seemed to fit together. The document outlines several pieces of evidence that supported Wegener's hypothesis, including matching coastlines, shared fossil distributions, and geological and climatic similarities between separated continents. It then describes how the theory of seafloor spreading provided further evidence when studies in the 1940s and 1950s showed the ocean floor was younger than the continents and spreading occurred at mid-ocean ridges. Paleomagnetic data from the seafloor also supported seafloor spreading and continental drift. Today the theory of plate tectonics unifies
Earth's History Notes
The document summarizes Earth's history from the Precambrian era to the present-day Cenozoic era in four parts. It describes the Precambrian era as spanning 88% of Earth's history, including the early evolution of life. The Paleozoic era saw the first life with hard shells and fossils, as well as plant and animal diversification on land and in the seas. Dinosaurs and other reptiles dominated during the Mesozoic era. Finally, the Cenozoic era is characterized as the time of mammals including humans, as well as flowering plants.
Continental Drift Theory
Alfred Wegener was a German scientist born in 1880 who developed the theory of continental drift, which proposed that the continents were once joined together in a supercontinent called Pangaea. He provided evidence from matching continental coastlines, fossil distributions, and past climates to support his hypothesis. Harry Hess was an American geologist born in 1906 who helped develop the theory of plate tectonics, proposing that the Earth's lithosphere is broken into rigid plates that move over Earth's surface. He contributed the idea of seafloor spreading to explain how new oceanic crust is formed at mid-ocean ridges. The theory of plate tectonics eventually subsumed and expanded upon Wegener's idea of continental drift

The positions of past continents can be determined using data like paleomagnetism, magnetic anomalies, paleobiogeography, paleoclimatology, and geological history. Alfred Wegener first proposed the theory of continental drift in 1915 to explain geological evidence that continents have moved over time, such as matching fossil and rock formations found across separated continents. Plate tectonics later expanded on this theory by proposing that Earth's lithosphere is composed of plates that move over Earth's asthenosphere, causing geological activity along plate boundaries.
Plate Tectonics
The document discusses the theory of plate tectonics, including what plates are made of, how they move at boundaries, and the evidence that supports plate tectonics. The lithosphere comprises the crust and rigid upper mantle, floating on the asthenosphere. Plates move at boundaries in three types - divergent, convergent, and transform - which are associated with volcanoes, earthquakes, and other surface phenomena. Evidence like matching continents, widespread fossil distributions, and matching rock formations support plate tectonics and the past connection of continents.
Continental Drift Theory and Plate Tectonic
I am a student of SUST and my subject is "Geography & Environment". Topic of this presentation is " Continental Drift Theory and Plate Tectonic ".
Continental Drift Notes - Jenny
Alfred Wegener first proposed the theory of continental drift in 1915, suggesting that the continents were once joined together in a single landmass called Pangaea that has since drifted apart. Wegener provided evidence from matching coastlines, fossil distributions, and climate patterns from over 250 million years ago to support his hypothesis. However, his theory was rejected by the scientific community at the time due to the lack of a proposed mechanism for continental movement and because it contradicted established ideas about mountain formation and Earth's cooling history. Continental drift was not widely accepted until new evidence emerged in the 1950s.
Plate Tectonics Lecture Chapter 2
The document discusses evidence that supports the theory of plate tectonics and continental drift. Fossils of the same organisms have been found in rocks from separated continents, implying the continents were once joined. Rock formations and deposits in Africa and South America also match up as if the continents were once attached. The movement of plates at mid-ocean ridges can be seen through magnetic patterns in volcanic rocks and helps explain sea floor spreading.
Continental Drift
1) Alfred Wegener proposed the theory of continental drift, which suggested that the continents were once joined together in a supercontinent called Pangaea before drifting apart over millions of years.
2) To support his theory, Wegener presented four pieces of evidence: the matching shapes of continental edges, identical fossil distributions, matching rock formations, and evidence of past climate zones that no longer align with the continents' current locations.
3) Despite this evidence, Wegener's contemporaries rejected his theory because he could not explain the mechanism that caused the continents to move. Acceptance of the theory required understanding how and why continental drift occurred.
Fossil evidence1[1]
Mesosaurus was a small, freshwater reptile that lived about 250 million years ago. It had an elongated head and snout, flattened tail for swimming, and likely ate fish and shrimp. Lystrosaurus was about the size of a pig with skull features suggesting it found food in water like a hippopotamus. Cynognathus was wolf-sized and active predator with short tail and limbs tucked under its body. Glossopteris was a deciduous plant with large number of fossilized leaves found in deposits, suggesting seasons. Photographs show glacial retreat of Muir Glacier and McCall Glacier between 1941/1958 and 2004/2003 respectively. Rock sequences in scattered continents show same three layers of
Chapter 14.1: The Continental Drift Hypothesis
8th Grade Integrated Science Chapter 14 Lesson 1 on the Continental Drift Hypothesis. This is a short introduction to Alfred Weger and the current evidence used to support his theory. There is a short explanation of the fossil and rock evidence found.
Continental drift
Alfred Wegener first proposed the theory of continental drift, which suggested that the continents were once joined together in a super continent called Pangaea before drifting apart to their current locations. Wegener's theory was initially rejected because he could not explain the driving force behind continental movement. Evidence that later emerged in support of continental drift includes: matching fossil and rock formations between continents, matching climate zones in pole and equatorial regions, and magnetic pole reversal patterns in ocean floor sediments. This evidence helped prove that continents have shifted positions over time.
Krakatoa
The document discusses plate tectonics and how it explains biogeographic patterns and geological phenomena. It describes how Philip Sclater observed that the flora and fauna differed between the eastern and western Indonesian islands over a distance of just 15 km (Wallace Line). Alfred Wegener later proposed continental drift to explain similarities between separated landmasses. The theory of plate tectonics was developed, explaining how convection currents in the mantle cause rigid tectonic plates to move and interact at boundaries.
Paleozoic Era 2-Geomorhology Chapter
The Paleozoic Era spans from 544 to 245 million years ago, beginning shortly after a global ice age. It includes six periods and witnesses the emergence of abundant fossils during the Cambrian Explosion. Throughout the Paleozoic, the continents were fragmented but eventually collided into a supercontinent called Pangaea by the late Paleozoic. Life evolved from simple organisms to include fish, amphibians, and early reptiles. The era ended with a mass extinction event paving the way for the Mesozoic Era.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
