Water Erosion
Wind Erosion
Mass Movement
Glaciers
Earth's Changing Surface
100
Water that moves over the Earth's surface.
What is runoff?
100
A deposit of wind blown sand creates a ....
What is a sand dune?
100
Force that pulls rock and soil down slopes.
What is gravity?
100
A large mass of ice and snow moving on land under its own weight.
What is a glacier?
100
When agents of erosion drop sediments they are carrying as they lose energy.
What is deposition?
200
The major force of erosion along coasts.
What are waves?
200
The two types of wind erosion.
What is deflation and abrasion?
200
Material moved by erosion.
What is sediment?
200
The process by which a glacier picks up rocks.
What is plucking?
200
Material moved by erosion.
What is sediment?
300
Stream or river that flows into a larger stream or river.
What is a tributary?
300
The process by which wind moves surface material.
What is deflation?
300
Four types of mass movement.
What are slump, creep, rockslide and mudflow?
300
The two types of glaciers
What are valley and continental glaciers?
300
This type of energy is produced when water is moving over the Earth's surface.
What is kinetic?
400
Two landforms that are created when water deposits sediment after it is eroded away.
What are alluvial fans and deltas?
400
The energy of ocean waves comes from this.
What is wind?
400
Results in gravestones and fenceposts tilting at odd angles.
What is creep?
400
It covers much of the island of Greenland.
What is continental glacier?
400
The force that affects a river's speed.
What is friction?
500
These three affect how fast a river flows and how much sediment it can erode.
What is the slope, volume of flow, and streambed shape?
500
Fine, wind-deposited sediment.
What is loess?
500
The most destructive kind of mass movement.
What is a landslide?
500
A ridge formed by the till left by a glacier where it begins to recede.
What is a moraine?
500
These are the four forces of erosion.
What is water, wind, ice and gravity?
