The direction toward which gravity pulls everything.
What is toward the center of Earth?
100
A large channel in soil formed by erosion
What is a gully?
100
A part of the shore that sticks out into the ocean.
What is a headland?
100
During the last ice age, this covered most of northern north America.
What is a continental glacier?
100
Hurricane Katrina caused a lot of flood damage as a result of the city of New Orleans being located on this on the Mississippi River.
What is a flood plain?
200
A type of mass movement in which a mass of rock and soil rapidly slips down a slope.
What is a slump?
200
The sediments deposited directly by a glacier.
What is a till?
200
Headlands stand out from the coast because they are made of harder rock that resists this by the waves.
What is erosion?
200
A ridge that is formed when the till deposits at the edges of a glacier.
What is a moraine?
200
The La Conchita one of these buried 23 homes and killed 10 people.
What is a landslide?
300
This is what occurs when water soaks the bottom of soil that is rich in clay.
What is a slump?
300
A large stream is often called this.
What is a river?
300
This is left standing when a sea arch collapses.
What is a sea stack?
300
A valley glaciers slides down quickly (can flow as much as 6 km per year) during this.
What is a surge?
300
Unlike gullies, streams rarely do this.
What is dry up?
400
This is the very slow downhill movement of rock and soil. It often results from the freezing and thawing of water in cracked layers of rock beneath the soil. You can see fits effects on telephone posts and fenceposts.
What is creep?
400
Small streams are often called these two things.
What are brooks and creeks?
400
Most sand comes from rivers that carry eroded particles of rock into this.
What is an ocean?
400
Gravity begins to pull glaciers downhill once the depth of snow and ice reaches more than this.
What is 30-40 meters?
400
The amount of runoff in an area depend on these five main factors.
What are: 1) the amount of rain an area receives 2) vegetation 3) type of soil 4) shape of the land 5) how people use the land
500
These sometimes occur where road builders have cut highways through hills or mountains.
What is a landslide?
500
Some possible solutions to reducing this are: including open areas for water absorption, including retention structures, and planting appropriate vegetation.
What is runoff?
500
Wind erosion slides or rolls larger particles; medium sized particles skip or bounce. And finer particles are carried through this.
What is air?
500
Glaciers can form only in an area where more snow does this.
What is falls than melts?
500
These are the five agents of erosion.
What are gravity, running water, glaciers, waves, wind.
