My son had to do another powerpoint in science class in 5th grade on Destructive & Constructive forces of nature. I helped him with this one and also shared it with my 5th grade students at the time. Students using technology.

1. Destructive &
Constructive Forces of
Nature

vinegar!

2. Volcano: a mountain
formed by lava and ash.

3. Lava is magma that reaches the Earth’s
surface. Volcanoes push up new rich soil to the
surface.

4. They form on the plates in
the Pacific Ocean

5. Tornadoes: a spiral
shaped wind storm

6. Tornadoes are common in
the middle of the U.S.

7. Tornadoes are like
spinning tops.
Destroy
Spiral shaped cones
buildings/homes

8. Hurricanes occur in the oceans. The eye
is in the center of a hurricane.

9. Hurricanes bring about
tropical storms.
Heavy rains causing
Strong winds
floods.

10. Earthquakes: shaking of
the ground.
Japan recently had 3 Fault: crack in the
earthquakes. Earth’s crust.

11. Earthquakes
California gets a lot of Fault: a crack in the
earthquakes. Earth’s crust.

12. Seismograph (instrument) Richter scale measures the
magnitude or strength of an earthquake

13. Tsunami: a HUGE wave

14. Thunderstorms:thunder,
lightning & rain

15. Lightning is Electricity!
A man struck by
Double Trouble!
lightning!

16. Wildfires: forest fires out
of control.

oxygen.

17. Wild Forest Fires
Smokey the Bear
helps to educate Humans / campfires
about fires.

18. In danger of burning this
beautiful home in the mt.

19. Trying to prevent
Flooding.
Building a barricade. Filling in sand bags.

20. Floods:destroy roads/
homes.

staying in a shelter.

21. Mass Movement- Mudslides can bury
homes, cars, and people.

22. A mudslide is a downhill movement of
rock & soil because of gravity.

23. BOULDER: a huge rock

24. Acid Rain: polluted water with
chemicals that destroy statues.

25. Water erosion: rocks over time
become round and smooth.

26. Weathering & Erosion

27. Weathering & Erosion

28. Weathering: water freezes (ice)
expands and breaks down rocks.

29. Water Erosion

30. Deposition: moving sediment into a NEW
LOCATION.
Sediment moving down the river and pouring into the delta- mouth of the river.

31. Changes to the Earth’s
surface create new
landforms.
