What is the rock that forms earth's crust?

bedrock

Name the difference between weathering and erosion.

weathering breaks rocks into sediments and erosion moves sediment from one place to another.

100

What are the two types of weathering?

chemical and physical?

200
When rocks are pulled downslope by gravity. Also a large part of weathering.

Mass wasting

200

Wind and water can carry sand and small pieces of rock to new locations. True or False

true

200

What is the definition of soil?

a layer of loose minerals and organic material found on top of bedrock

200

The difference between erosion and deposition is: a. erosion moves sediment from one place to another and deposition is a physical feature on the Earth. b. deposition is the process of dropping , or depositing , sediment in a new location and erosion is the process of moving sediment from one place to another.

200
Gigantic formations of ice that do not completely melt over the course of a year.
a glacier
300
The process by which weathered rock is picked up and moved to a new place.
erosion
300

Weathering over long periods of time breaks rock into ____________ pieces.

smaller

300

What is the definition of humus?

a component of soil that is made up of organic material and partially decomposed plants.

300

what is the difference between root wedging and freezing?

root wedging is when rocks get broken down as plants grow underground and freezing is when water gets in between rocks and freezes putting pressure on the rocks.

What are the components of soil?

air, water, humus, mineral components.

What is a characteristic of calcite?

When acid is added to it, it begns to fizz and bubble.

500
The sudden movement of rocks and soil down the side of a hill because of gravity and rain.
landslide

All of the following are forces that change landforms EXCEPT: a. wind b. moving water c. glaciers c. physical features
physical features

What makes up the mineral component of soil?

silt, sand, and clay

How did sediments get into the soil?

As they got broken down, the sediment was deposited either washed off a hill or from a stream.
