2. This change to the Earth’s surface
occurs very, very slowly

3. In this type of erosion
huge sheets of ice move
rock and debris from one
area to another

4. This type of erosion
helped create the Dust
Bowl in the 1930s

5. This type of erosion creates
landslides

6. This type of erosion moves
rock and debris that have
are rounded due to running
water. This happens many
times before the rock breaks.

7. In this type of weathering
Water seeps into cracks in
the rock. The water freezes
and expands several times,
eventually breaking the rock.

8. In this type of weathering, acids
in rain break the chemical bonds
in the rocks, creating a new type
substance. The old rock is gone.

9. In this type of weathering,
rocks are tumbled and ground
against each other because
of the current in the water.

10. In this type of weathering
the rock becomes weaker
and weaker because as it gets
warmer it expands, then when it
cools off it contracts. This heating
and cooling can happen many times
before the rock breaks apart.

11. In this type of weathering
rocks break apart because
something is growing in the
cracks

12. The breaking down of rocks
into smaller pieces

13. The carrying away of rocks
that have weathered

14. This is the breaking down
Of rocks into smaller pieces,
But the old rock is gone.

15. This is the breaking down
of rocks into smaller pieces
but you can put the rock back
together again.

16. This is what happened
to my neighbors rock.

17. This is the first step
of the Scientific Method

18. When scientists make an
educated guess it is called this.

19. After scientists ask a question,
they do this to see if someone
has already answered it.

20. During an experiment, scientists
carefully use their eyes, ears, nose
fingers to do this so they can
record what they _________.

21. The final step of the Scientific
method is to _________________
their findings with other people.

22. This is the shaking of the
Earth that occurs when two
plates move past each other

23. This forms when magma
Erupts from the crust.

24. Hot molten rock inside the
Earth is called this

25. Hot molten rock outside the
Earth is called this.

26. Who is the best science
teacher?
