100

The process of moving and carrying of sediment and rocks from one place to another.

Erosion

100

This is a giant wave of water caused by an earthquake.

Tsunami

100

This is the breaking down of rocks into smaller pieces.

Weathering

100

A natural land feature on Earth's surface

Landforms

100

An example of deposition

sand dunes, deltas, etc

200

a slowly moving mass or river of ice formed by the accumulation and compaction of snow

Glaciers

200

This is a sudden shaking of the earth's crust along a fault

Earthquake

200

When water in cracks of rocks freeze, it _______________ causing the rock to break apart.

Expands

200

Very hot, partly melted rock that is below the Earth's surface

Magma

200

An example of erosion

wind carrying small pieces of rock away, water carrying rock into a stream, etc

300

These form when sediment or sand is eroded by wind and create hills and mounds.

Sand Dunes

300

A landform that forms at an opening in Earth's crust where magma reaches the surface

Volcano

300

These can grow through rock causing it to break apart.

Plant Roots

300

Magma that reaches the Earth's surface

Lava

300

An example of weathering

ice freezing in cracks of rocks and breaking, rocks scraping each other, etc

400

The laying down or dropping off of sediment.

Deposition

400

The rapid downhill movement of a large amount of rock and soil

Mudslide

400

Rocks can feel very _____________ if they have been rolling in water (Think of a rock in a stream or lake)

What is smooth?

400

Fast moving water that can uproot trees, carry away big rocks, and change where rivers flow

Flood

400

Periods of unusually low rain or snowfall

Drought

500

This land feature forms at the base of rivers where sediment is deposited.

Deltas

500

Name 3 ways land can be eroded quickly or suddenly. (example: earthquake)

Tsunami, earthquake, volcano, landslide, mudslide, lahar, tornado etc.

500

Name 2 causes of weathering.

water, wind, plants

500

A break or crack in rocks where Earth's crust can move suddenly

Fault

500

Type of weathering that can be caused by acid rain (Hint: NOT physical weathering)
