Processes that build up Earth's surface are called

The breaking down of rock at or near Earth's surface is called

This type of weathering breaks rock into smaller pieces but does not change the rock chemically (2 answer choices)

These are loose particles of weathered rock such as pebbles or sand.

Over time, repeated freezing and thawing of water in a rock may split it apart. Scientists call this

This type of weathering changes rock into one or more new substances that are usually weaker than the original rock.

One example of chemical weathering is

The main agent of erosion is

The activities of these can speed up erosion

These two structures help hold back flood waters and prevent flood damage.

These help prevent flooding during heavy rainstorms because water runs off roads and other land into them.

Which statement is true?

People build these along shores to absorb the pounding of waves and protect the land and buildings

Taking sand from one location and adding it to an eroded beach to rebuild it is called

This is a method in which farmers plant crops on formations similar to steps along hillsides

These can help farmers prevent soil from washing or blowing away

Scientists who study earthquakes are called

These are scientists who study the earth and its landforms

Examples of constructive forces are (select more than one)

These are examples of destructive forces. Select more than one.

A sudden movement of rock and soil down the side of a hill

The dropping of weathered rock by water, wind, or glaciers

A flat piece of land made up of sediment deposited by a river near its mouth

A wide, flat area of land formed from sediment deposited by a river outside of its banks

A hill of sand deposited by wind

plowing along the contours of the land in order to minimize soil erosion

method of farming in which steps known as terraces are built onto the slopes of hills and mountains; helps to prevent erosion

innermost layer of the earth; hottest; solid iron and nickel

the process by which weathered rock is picked up and moved

a huge sheet of ice that moves slowly across the land

a force that pulls objects toward each other

a surface feature of earth, such as a mountain

zone bordering the Pacific Plate where many earthquakes and volcanic eruptions occur

crack in earth's crust; seismic activity can occur here

molten rock BELOW earth's surface

molten rock ABOVE earth's surface (flowing onto earth's surface)

sudden shaking of the crust; usually at plate boundaries

opening in the earth's crust from which ash, molten rock, and gases flow onto the crust

moving toward each other (as in when tectonic plates move toward each other)

moving away from each other (as in when tectonic plates move away from each other)

a theory stating that the sections of crust move over the mantle

thickest layer of the earth; below the crust; putty-like molten rock

outer-most layer of the earth; thinnest; we live on it
