100

When sediment is picked up and dropped in a new location.

What is deposition?

100

The process of wearing away or breaking down rocks by natural means.

What is weathering?

100

When two convergent plates collide, what two surface features might form?

What are mountains and volcanoes?

100

A break in Earth's crust where most earthquakes can occur.

What is a fault?

100

A raised bank of sediment or rocks built along the edges of a river to prevent flooding.

What is a levee?

200

A hill of sand formed and shaped by wind.

What is a sand dune?

200

The process by which weathered rock is picked up and moved by wind, water, ice, or gravity. 

What is erosion?

200

When two plates divide at a divergent plate boundary, what surface features are created?

What are rifts, ridges, and trenches?

200

Molten or melted rock beneath Earth's surface.

What is magma?

200

A structure built across a river to control its flow and prevent other lands from flooding.

What is a dam?

300

A landform of sand, sediment, and silt particles deposited at the mouth of a river.

What is a delta?

300

When weathering eats away limestone underground, a ___________ can occur. 

What is a sinkhole?

300

At a transform plate boundary, what might form and occur?

What is a fault line and earthquakes?

300

To build up Earth's surface is known as a __________________ process.

What is constructive?

300

These help prevent flooding by directing rain water through pipes underground which lead to nearby bodies of water.

What is a storm drain?

400

When a river overflows from rain and forms a wide, flat landform.

What is a floodplain?

400

What form of erosion causes water to flow downhill?

What is gravity?

400

The movement of the ground caused by the sudden release of energy in the earth's crust.

What is an earthquake?

400

To wear away at Earth's surface is known as a ___________________ process.

What is destructive?

400

What do seismologists do? And can this help predict certain destructive processes?

Seismologists study earthquakes. They measure seismic activity to monitor and predict where earthquakes are most likely to occur. They are able to monitor the movement at fault lines to help predict earthquakes.

500

A ridge of sediment deposited when a glacier melts.

What is a moraine?

500

The Colorado River carved its way to make the Grand Canyon. This is an example of what destructive process?

What is erosion?

500

A mountain made of lava and ash and where magma is released to the surface of the Earth.

What is a volcano?

500

The natural shape or landform on Earth. 

What is a surface feature?

500

How are humans and technology used for beach nourishment?

Coastal workers are able to replace sand on beaches from the bottom of the ocean or other water sources. Humans can use plants and build seawalls or jetties to prevent coastal erosion.
