Deposition is the laying down or settling of

eroded materials

300
Name the 2 different types of weathering.
What is mechanical weathering and chemical weathering?
300
Define Deposition
What is a process that drops sediment to form landforms?
300
Is weathering constructive or destructive?
What is destructive?
300
Layers of sediment forming at the bottom of the ocean; Deltas forming at the mouths of rivers; Waves dropping sand on the beach
What is Deposition?
300

A type of erosion that changes landforms slowly over time creating a U shaped valley.

Ice erosion or glacial erosion

400
The name for the smaller pieces of rock that are formed when mechanical weathering breaks down larger rocks
What is sediment?
400
These 3 surface features are formed because of which process: sand dune, delta, and alluvial fan
What is deposition?
400
Is deposition constructive or destructive?
What is constructive?
400
Wind blasting sand at rock and carving out arches; A mudslide flowing down a steep hill
What is Erosion?
400
When two tectonic plates push together and move upward, what surface feature is created?
What is mountains?
500
Explain chemical weathering.
What is: water seeps down into the earth, and dissolves certain minerals in rocks. This causes the rocks to break down into smaller pieces.
500

How are sand dunes created? Where can they be found?

Wind and water deposit eroded sand through deposition.

Found in deserts, rivers, and oceans

500
Is erosion constructive or destructive?
What is destructive?
500
Water getting into cracks, freezing, and breaking the rocks
What is Weathering?
500
How are volcanoes formed?

Like mountains, from plate movement.
