Weathering
What is the breaking or peeling away of rock in layers?
Exfoliation
What is an area that consists of a relatively large stream and any smaller streams that flow into it?
Drainage system
"Rivers of ice" that slowly flow down the mountainous regions into valleys
What is a valley glacier?
What is the eroding action of windblown sand known as?
Abrasion
What are the winding, looping curves of rivers?
Meanders
Occurs when rainwater or melted ice soaks into tiny cracks in a rock and freezes, which then causes the rocks to split apart

Large, deep grooves and scratches in rock that are produced by glacier
What are striae?
What is a sharp ridge that divides two cirques?

Vegetation
Terraces - fields that are in stair-steps
Strip-cropping: planting alternating strips of erosion-prone and erosion preventing crops

What is the difference in Creationist's vs evolutionist's view of an ice age?
Creationists - only one
Evolutionists - many occurred
Name and define the three types of wind erosion.
Suspension - wind can lift it and transport it over long distances
Saltation - particles are lifted by wind but then dropped abruptly
Creep - particles are rolled by wind
Name the three canyons (besides the Grand Canyon), including how they were formed.
Providence Canyon - formed by poor farming practices in the 1800's
Burlingame Canyon - formed from large amounts of water being diverted into a stream
Canyon Lake Gorge - formed when a lake overflowed and sent a ton of water into a valley
