Rocks are broken down into tiny particles by wind and water over a long period of time. Where do most of the tiny particles of rock end up after they have been broken down and blown away?
They become parts of mountains and cliffs.
They turn into salt water in the ocean and seas.
They are broken down and become either sand or soil.
They become parts of newly formed animals.
They are broken down and become either sand or soil.

Dannell created a model of a glacier to help explain how glaciers change the surface of Earth. He froze two large blocks of ice. One block was pure water. The other was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Dannell’s model explain how glaciers change Earth’s surface?
The rocks and sand contained in some glaciers fill the grooves in Earth’s surface.
The water in pure glaciers cools Earth’s surface.
The rocks and sand contained in most glaciers create grooves in Earth’s surface.
Pure glaciers and glaciers that contain rocks and sand affect the Earth in exactly the same way.
The rocks and sand contained in most glaciers create grooves in Earth’s surface.
