Definition
| ______ are moving masses of ice and snow that are responsible for creating many landforms on Earth through erosion and deposition. |

Definition
| ______ is a ridge of material deposited in the middle and along the sides of a glacier |
|
|
Term
|
Definition
| ______ is a type of erosion in which gravity alone causes loose materials to move downslope. They can happen quickly or slowly. |
|
|
Term
|
Definition
| ______ is a mass movement that happens when loose materials or rock layers slip down a slope, and a curved scar is left where the slumped materials originally rested. |

Definition
| ______ is a mass movement that occurs when sediments slowly inch their way down a hill and that is common in areas of freezing and thawing. |

Definition
| ______ is material deposited by the melt water from a glacier |
|
|
Term
|
Definition
| ______ is a mixture of different-sized sediments dropped from the base of a slowing glacier and that can cover huge areas of land. |
|
|
Term
|
Definition
| ______ is the dropping of sediments that occurs when an agent of erosion loses its energy of motion and is no longer able to carry its load |
|

Term
|
Definition
| ______ occur in mountain valleys where the elevation is high enough that the snow does not melt all year round. |
|
|
Term
|
Definition
| ______ is a process that adds boulders, gravel, and sand to a glacier's bottom and sides as water freezed and thaws and breaks off pieces of surrounding rock |
|

|
Definition
| ______ are when large blocks of rock break loose from a steep slope and start tumbling. |
|
|
Term
|
Definition
| ______ is erosion that occurs when windblown seditments strike rock, scraping the surface and wearing it away. |
|
|
Term
|
Definition
| ______ are wind deposits of fine-grained, tightly pack sediments |
|
|
Term
|
Definition
| ______ is the process that wears away surface materials and moves them from one place to another by agents such as gravity, glaciers, wind and water. |
|

|
Definition
| ______ are huge masses of ice and snow that covered 28% of the Earth 2-3 million years ago. |
|
|
Term
|
Definition
| ______ is a winding ridge of sand and gravel left by a melting glacier. |
|
|
Term
|
Definition
| ______ is erosion caused by wind blowing across loose sediments, eroding only fine-grained particles such as clay, and sand, and leaving behind coarse sediments. |
