Science Topic 9 Test

The type of weathering in which rock is physically broken into smaller pieces.

The flat, wide area of land along a river.

The process by which water, ice, wind, or gravity moves weathered particles of rock and soil

The process that breaks down rock through chemical changes.

Process in which sediment is laid down in new location.

Any large mass of ice that moves slowly over land.

The process by which wine removes surface materials.

Any one of several processes by which gravity moves sediment downhill.

A deposit of wind-blown sand.

The loose, weathered material of Earth’s surface in which plants can grow.

The geologic principle that the same geologic processes that operate today operated in the past to change Earth’s surface.

A wind-formed deposit made of fine particles of clay and silt.

Small, solid pieces of rock that come from rocks or the remains of organisms.

Dark-colored organic material in soil.

Is a glacier that covers much of the continental or large island.

Is a long, narrow glacier that forms when snow and ice buildup in a mountain valley.

The two processes by which glaciers erode the land are:

_____________- occurs as a glacier flows over the land.

Rocks remaining embedded (stuck) on the bottom and sides of the glacier get dragged across the land like sandpaper in a process called ________________.

The energy from most waves comes from the ___________.

The primary agent of erosion that has shaped Earth’s geosphere for billions of years is the moving water of the hydrosphere. The moving water is called _____________ and as the water moves over land, it picks up and carries sediment.

_____________ causes runoff and the sediment it carries to flow downhill.

When runoff flows over the land, it may cause a type of erosion called _______________, where thin layers of soil are removed.

A ________________ is a channel along which water is continually flowing down a slope.
