An erosional process by which rocks are ripped out of the ground by glacial movement is called:
The geographical region where snow accumulates and feed the growth of a glacier is called:
the zone of accumulation
Glacial formation requires:
temperatures below freezing during the summer months
The interior of a glacier is almost always at a stand-still.
A ___________ moraine forms at the front of the glacier and marks the long-term, stationary position of the farthest advance of the glacier.
Tilt obliquity has a cycle that averages about ___________ years.
Currently, ice covers 30% of the earth's surface.
Orbital precession varies on an approximately __________-year cycle.
Glaciers cannot carry anything besides the ice they are made of.
When meltwater accumulates at the base of a glacier, providing a lubricant between the underlying rock and the glacier, the glacier moves through the process called:
What type of feature is formed by the gradual thickening, compaction, and recrystallization of snow and water over time?
The most recent glaciation impacting the United States was the Wisconsin glacial period.
When there is more accumulation of snow than there is loss, the equilibrium line moves down the valley and the glacier:
_______ are oscillations in a body of water that form due to the wind blowing across the surface of the water.
A low wall built at a right angle from the shore out a short distance into the water is called:
In the open ocean, the height of the 2004 tsunami was _____ feet, however, near the shore the seismic sea wave grew to an estimated _____ feet.
Fine grains of sediment are held in the air through:
The largest of the oceans on Earth is the
__________ is a broad horizontal surface that is upheld by resistant caprock.

Another name for a seismic sea wave is a
______________ is the current that develops parallel to the coast when waves approach a coast at an oblique angle.
In deserts, the vegetation cover is relatively:
A steep-sided hill or peak that is often a remnant of a plateau or mesa is called a butte.
Eolian processes are associated with the way wind erodes, transports, and deposits sediment.
_______ is a linear bank of land that extends into a bay made by the deposition of longshore sediment.
The lowest of high tides are a result of neap tides.
The influence of the rainshadow effect is another factor in the development of arid and semi-arid regions.
Sand dunes are not sensitive to climate change.
_______ are regular and predictable oscillations that occur with respect to the level of the world's oceans.
The Dust Bowl of the 1930s in the United States in an example of desertification.
___________ is the nearshore zone that is regularly uncovered through the tidal fluctuations and movement of surf.
The speed of the wind blowing over arid locations impacts the size of the particle picked up.
