Weathering
What is the slow process that breaks down rocks into smaller pieces?
Weathering
What is the process of weathered rock moving from one place to another?
Erosion
What is the process of eroded materials being dropped off in another place?
Deposition
How do sandy beaches form?
Waves pounding pebbles into smaller and smaller pieces.
What is a variety of plants that cover a region?
Vegetation
How can living things cause weathering?
Ex: tree roots forcing open cracks in rocks.
Is erosion a natural process?
Yes
Deposition is the (blank) off of sediments.

long or short
What is the speed in which glacial erosion takes place?
Slow
What do floodplains, sandbars, and river deltas all have in common?
They have all been formed by water erosion.
Humans cause pollution when what is left in the ocean?
plastic and chemicals
Give me an example of physical weathering.
Ex: Flowing water making rocks smooth.
Ex: Waves breaking off small pieces of a cliff.
Ex: Freezing and melting causing cracks in rocks.
What type of changes does erosion cause?
Physical changes
Can the location of sand dunes change often?
Yes
What natural forces most likely cause a landslide?
Water and gravity
How can you tell that a flood has happened?
Soil and rocks are on the road and sidewalks.
What kind of landform would be most effected by weathering?
A mountain
How can glaciers cause erosion?
Glaciers cause erosion by picking up rocks and soil and sediment as they move slowly across the land.
How does glacial deposition happen?
When glaciers melt, they drop the rocks they were carrying.
Which process created the Grand Canyon?
Water erosion.
What is sediment?
Bits of rock, sand and silt caused by the weathering of rocks.
