More Icy Wisdom
This is what causes glaciers to go away.
What is they melt?
These are the three things that can affect how much sediment a stream can carry.
What are slope, volume, and the shape of the stream bed?
This is what we call mounds of wind-deposited sand.
What are dunes?
This is the large mass of till left behind at the the front of a glacier as it recedes?
What is a terminal moraine?
This is the term we use to describe any one of several processes that move sediment downhill in large amounts influenced by gravity.
What is mass movement?
This is what we call a long, narrow, deep inlet of the sea between high cliffs, as in Norway and Sweden, formed by the submergence of a glacier valley.
What is a fjord?
What is a gradient?
The slope of a river or creek bed.
Daily Double*
This is the process whereby small grains of sediment and soil are lifted up and carried away by the wind.
*add or subtract the points twice
What is deflation?
What are giant thick sheets of ice that can cover large areas?
continental glaciers
This is the difference between creep and slump.
What is speed? Slump is fast, creep is slow.
What are lateral moraines?
What landforms can streams create? (must get all three. no partial credit)
floodplain, delta, alluvial fan
What is abrasion?
the wearing away of rock by rock
These are two terminal moraines closest to us in MA.
What are Long Island and Cape Cod?
This is what we call a mass movement in which soil with a high percentage of water slides downhill with many of the qualities of a fluid.
What is a mudflow or mudslide?
According to scientists, this is how long ago the last Ice Age occurred.
What is 10,000-15,000 years ago?
This is what we call the amount of sediment carried by a river or stream.
What is its load?
What is loess?
thick deposits of fine wind-blown sediment
This is what glaciers do to erode the earth.
What is they remove features that existed before the ice did?
Are weathering and erosion constructive or destructive forces?
Answer: both; they tear down old landforms and build up new ones.
This is what we call a bowl-shaped valley on a mountain that was carved out by a glacier.
What is a cirque?
How can the shape of a stream bed affect how much sediment a stream can carry?
What is the more friction or resistance created by a stream bed, the less sediment it can carry?
This is the name of the adorable little snowman in Frozen.
What is Olaf?
This is what we call a sharp mountain ridge carved out by a glacier.
What is an arete.
*The other Daily Double*
This is the equation for universal gravitation.
Double the point value for this question.
What is Fg = Gm1m2/r2 where G is the universal gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them?
