Weathering
The breaking down of rock on Earth's surface into smaller pieces.
What is weathering?
This is the force responsible for mass movements.
What is gravity?
These are the two type of glaciers.
What are valley and continental glaciers?
Valley glaciers are sometimes called alpine or mountain glaciers and continental glaciers can be called ice sheets.
A valley eroded by a river has this shape.
What is v-shaped?
What are limestone, dolostone and marble? (any 2 are acceptable)
An example of this type of chemical weathering is demonstrated when iron in certain rocks turns a rusty color.
What is oxidation?
This is a mass movement that is composed of mostly snow and ice.
What is an avalanche?
This is the shape of a valley formed by a glacier.
What is u-shaped?
This is the depositional feature found at the end of a river when it reaches a large body of water?
What is a delta?
This name is given to a cavern when the roof of it caves in.
What is a sinkhole?
This is a type of physical weathering that occurs when water soaks into cracks in rocks and breaks them apart when the water freezes.
What is frost wedging?
True or false? Higher levels of water in the ground make soil on slopes more likely to slide downhill.
What is true?
This is ridge that forms by the erosion between two valley glaciers.
What is an arete?
This term describes the curve in the shape of a river.
What is a meander?
What is a stalactite?
Limestone and marble are two rocks that are susceptible to this type of chemical weathering?
What is reaction with acid (rain)?
This mass movement contains mostly boulders and rock and very little soil?
What is rockfall or a rock slide?
Glacial depositional features such at drumlins, kames and moraines are composed of this material.
What is glacial till? (This is mostly loose sediment such as sand and gravel.)
This is a smaller river or stream that flows into a larger river. The St. Croix River is one of these for the Mississippi River.
What is a tributary?
This occurs when a stalactite and stalagmite grow together.
What is a column?
This is a type of physical weathering whereby rocks break down by friction with water and wind.
What is abrasion?
The mass movement was first stage of the eruption of Mt. St. Helens.
What is a landslide?
The vast majority of lakes in MN are this type formed by chunks of glaciers breaking off and settling into depressions.
What are kettle lakes?
This term is given to a meander of a river that gets cut off from the river and becomes a lake.
What is an oxbow lake?
This are of Minnesota was not affected by the most recent glacial action and has significant Karst topography.
What is SE Minnesota.
