This change to the Earth’s surfaceoccurs very, very slowly

In this type of erosionhuge sheets of ice move rock and debris from onearea to another

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

This type of erosion createslandslides

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

In this type of weatheringWater seeps into cracks inthe rock. The water freezesand expands several times, eventually breaking the rock.

In this type of weathering, acidsin rain break the chemical bondsin the rocks, creating a new typesubstance. The old rock is gone.

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

In this type of weatheringthe rock becomes weaker and weaker because as it getswarmer it expands, then when itcools off it contracts. This heatingand cooling can happen many times before the rock breaks apart.

In this type of weatheringrocks break apart because something is growing in the cracks

The breaking down of rocksinto smaller pieces

The carrying away of rocksthat have weathered

This is the breaking downOf rocks into smaller pieces, But the old rock is gone.

This is the breaking downof rocks into smaller piecesbut you can put the rock backtogether again.

This is what happenedto my neighbors rock.

This is the first stepof the Scientific Method

When scientists make aneducated guess it is called this.

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

During an experiment, scientistscarefully use their eyes, ears, nosefingers to do this so they can record what they _________.

The final step of the Scientificmethod is to _________________their findings with other people.

This is the shaking of theEarth that occurs when twoplates move past each other

This forms when magmaErupts from the crust.

Hot molten rock inside the Earth is called this

Hot molten rock outside theEarth is called this.
