A large mass of moving ice that forms on land and remains from year to year is called what?
The removal and transport of material by wind, water, or ice is called what?
erosion
The breaking down of rocks by physical process is called what?
mechanical weathering
True or False Shoreline erosion increases during the winter.
True
Unsorted rocks and sediments left behind when a glacier melts is called what?
Till
True or False Material eroded by rivers is usually lost in the ocean.
False. It is deposited and becomes part of another landform
Which type of rock is most easily weathered?
a. sedimentary b. metamorphic c. igneous d.quartz

b. volcanic eruptions
c. earthquakes
d. all of the above
d. all of the above
heavy rain or snow melt, volcanic eruptuions, earthquakes
Water is responsible for mechanical weathering of rocks through changes in what?
temperature
True or False An erratic can indicate an area through which a glacier traveled.
True
The downhill movement of loose rocks and soil caused by gravity is called what?
mass wasting
True or False A desert rock that is smooth on one side but rough on another side was likely shaped by deflation.
False, The rock was likely shaped by abrasion
True or False Waves erode cliffs only through the force of their pounding.
False Waves erode cliffs both by their pounding and by abrasion through the particles they can carry.
False Repeated cycles of extreme heat and cold are a major factor in mechanical weathering.
Which of the following landforms was most likely created through glacial deposition as opposed to glacial erosion?
a. arete b.tarn c. horn d.moraine
d. moraine
Landslides, mudflows, and soil creep are all similar in that they all involve moving soil where? (what direction)
downhill
Waves erode cliffs by what two ways?
pounding of the waves and by abrasion then eroding away the particles they have broken up
A liquid mass of mud and debris rapidly flowing downhill through natural channels is best called a what?
a. landslide b. mudflow c. earthflow d. solifluction
mudflow
Describe three major forces of nature that contribute to erosion.
Wind, waves, rivers, glaciers
The process in which carbon dioxide dissolves in water to create carbonic acid is called what?
carbonation
Arete, horn, and tarn are shaped by glacier weathering, erosion, or deposition?
How is climate a major factor of mechanical weathering in a desert?
extreme hot and cold
Describe carbonation.
