Percentage of the earths surface under desert
Form of erosion where sediment carried along the bottom of a glacier acts like sandpaper that smooths surfaces
How glaciers erode surfaces
Type of glacier formed in mountain areas
sharp edged ridges formed between two troughs
Bowl-like depression formed by frost wedging and plucking steep cliffs at edges.
Cracks formed in the top 150 feet of glacier.
alternating directions of layers in lithified sand dunes
Process that removes fine materials from the soil surface, leaving coarser materials behind, causing the whole surface to drop lower and become coarser over time.
arid regions covering approximately 30% of the earth's surface
Streams that only run when there is precipitation and then dry up quickly
submerged glacial trough that formed when sea level was lower. Also called arm of the sea
All sediments deposited by a glacier, containing sediment of all sizes
Thick ice mass formed by the accumulation, compaction and recrystallization of snow
Tributary troughs which are higher in elevation than the main trough
sharp pyramid shaped peaks formed between more than two troughs
Large bodies of ice that form on continents and grow outward in all directions
mountain peaks buried in sediment
Wind-blown deposits of fine silt and mud laid down in broad layers
