What is the breaking down of landforms into smaller pieces called?

Weathering

100

What is the moving of weathered earth to a new place called?

Erosion
100

Name three landforms.

Mountains, hills, canyons, valleys, delta's, sand dunes

100

What land feature is essential for deposition?

Rivers or streams

100

What is the collecting or dropping of sediment in a new location?

Deposition

200

How do sand dunes form?

Wind picks up loose, dry sand from the ground and carries it (erosion). When the wind slows down, it can’t carry as much sand, so it drops it (deposition). As more sand gets deposited in the same place, a small pile forms. Over time, wind keeps adding sand, and the pile grows into a dune.

How is erosion different than weathering?
Weathering is the breaking down of rock, and erosion is the movement of rock and soil over Earth's surface.
200
What do you call layers of sediment that are compacted together over extremely long periods of time?

Sedimentary Rock

200

2 landforms created by deposition.

What is Deltas and Sand Dunes?

200

Explain two different ways that erosion by water can occur.

Rain, running water (rivers) carrying sediment, rivers flowing over a piece of rock over a long period of time (ex. the Grand Canyon), expanding by freezing into rock cracks and breaking the pieces of rock off

300

What is a big u-shaped valley that is formed when a river erodes a mountain over millions of years?

Canyon

300
What is erosion by water?
The process of sediment being moved by flowing bodies of water.
300

What are the cause agents for weathering, erosion, and deposition that create landforms?

Glaciers (ice), water, and wind.

300
What relation does deposition have with erosion?
Eroded sediments are dropped, it ends the process of erosion.
300

What might happen to an area if increased flooding led to a river moving higher and faster compared to a normal time of rain?

The rock on the sides of the river could weather faster. 

400

Landform caused by coastal rock weathered by waves.

What are cliffs?

400

Name 2 landforms caused by erosion.

Canyons, cliffs, valleys

400
What causes landforms?
The process of weathering, erosion, deposition, tectonic uplift, and volcanoes.
400
Does deposition tear down or build up Earth's surface?
Builds up. Deposited sediments add on to the the Earth 's surface.
400

The Brazos River is the longest river in Texas. After moving through the state, it empties into the Gulf of Mexico. As the river reaches the gulf, what landform would you most expect to see? 

Delta

500

What is physical weathering?

The breaking down of rock into smaller pieces by the action of wind, water, and temperature change (ice).

500
What is erosion?
The process in which wind, water, ice or other things move pieces of rock and soil over Earth's surface.
500
What are landforms?
Naturally occurring features of the Earth's surface.
500
What is deposition?
Occurs when eroded sediments are dropped at another location.
500
How are weathering, erosion, deposition, and landforms connected?
Weathering, Erosion , and Deposition create a cycle that builds up and tears down Earth 's surface. Landforms are the outcome of the cycle.
