This Presentation is For Students of Class 10th CBSE Board. This Presentation is on Natural Resources. The Main Topics of this Presentation Are Renewable and Non Renewable Source, Solar Energy, Wind, Forests and Fuel.

1. Natural Resources

2. 1. A NATURAL RESOURCE IS A SOURCE OF PRODUCTS THAT
ARE INHERENT TO EARTH
2. NATURAL RESOURCES INCLUDE RENEWABLE AND NON-
RENEWABLE RESOURCES
3. NATURAL RESOURCES ARE EXPLOITED TO CREATE THE
PRODUCTS AND SERVICES THAT WE DEPEND ON
4. NATURAL RESOURCE EXTRACTION CAUSES GREAT
ENVIRONMENTAL DISRUPTION
What is a natural resource?

3. There are Two types of Resources -
RENEWABLE NON
RENEWABLE

4. RENEWABLE SOURCES 
Wind Solar Energy Forest

5. WIND 
• Wind is caused by the uneven heating of the
atmosphere. Some areas of the world, such as
costal regions, have more wind than others
because the terrain of the area is relatively flat
and has few obstacles to block the wind from
blowing.
• The power of the wind drives sailboats. It has
been used to power windmills that grind grain.
Windmills can also use the circular movement of
the blades to turn a turbine. This is increasingly
used as a means of generating electricity.

6. SOLAR ENERGY 
• The sun is the closest star to Earth. It brings
heat and light to the world. Some areas of the
world, such as those closest to the equator,
have more sun than others.
• The sun shines naturally but it is not affected
by human activity. It cannot be used up.
However, its intensity varies with the seasons,
and it is not available at night.

7. Non-Renewable Resources
• Fossil Fuels
1.Coal
2.Petroleum
3.Natural Gas

8. • Fossil fuels take millions of years to form. They
are the product of the fossilized remains of
dead plants and animals that have been
exposed to the heat and pressure deep within
the earth’s crust. There are many types of
fossil fuels, such as petroleum (gasoline),
natural gas, and coal.

9. FOREST 
• Forests have moderate climate, help cleanse
the air and water, and house wildlife. They
also provide thousands of wood products and
related jobs.
• Trees are used to make paper, hockey sticks,
flooring and food
• Forests face threats from fire, pollution,
erosion and acid rain

10. • Fossil fuels are arguably one of
the most valuable natural
resources in modern times. It is
estimated that 86 percent of the
world’s energy comes directly
from burning fossil fuels. Fossil
fuels are the source of energy
for almost every machine,
including the generators that
produce electric energy.

11. • Because fossil fuels take so long to form, they
are being consumed faster than they can be
produced. Fossil fuels are a major contributor
to air pollution because when they are burned
they release many dangerous gases such as
nitrogen dioxide, methane, and carbon
dioxide.
