Erosion/Weathering
The removal of weathered rock and soil from its original location
What is erosion?
slow, steady downhill movement of loose, weathered Earth materials
What is a creep?
A large moving mass of ice is called a(n) __.
What is a glacier?
influenced by vegetation, precipitation, soil composition, and slope
What is runoff?
A landslide that occurs on steep slopes in mountainous areas with thick snow is
called a(n)
What is an avalanche?
A depression that receives more water than is removed will exist as a __ for a long period of time.
What is a lake?
The process in which materials on or near the Earth’s surface break down and change
What is weathering?
rapid downslope movement of a mass of loose sediment
What is a landslide?
Glaciers can form along the equator, glaciers carve U-shaped valleys, only valley glaciers flow, glaciers produce moraines (Which is not true?)
What is only valley glaciers flow?
the measure of the volume of stream water that flows over a particular location within a given period of time
What is discharge?
giant waves caused by earthquakes or volcanic eruptions under the sea
What is a tsunami?
A pile of windblown sand develops into a(n) __.
What is a dune?
The loose covering of weathered rock particles and decaying organic matter, called humus, that overlies the bedrock of Earth’s surface and serves as a medium for the growth of plants
What is soil?
rapidly flowing, often destructive mixtures of mud and water
What is a mudflow?
An unsorted ridge of till, called a(n) __, is left behind after a glacier melts.
What is a moraine?
the land area whose water drains into a stream
What is a watershed?
Heavy accumulations of excess water from large regional drainage systems can result in downstream floods.
What is true?
__ is the method of transport for all particles small enough to be held up by the turbulence of a stream’s moving water.
What is a suspension?
__ occurs when particles such as sand rub against the surface of rocks.
What is Abrasion?
Underground pipelines break, trees become bent, vertical structures become tilted.
What are indications that a creep has occurred?
When a large block of ice breaks off and the surrounding area is covered by sediment, a large depression, or __ hole, is left behind when the ice melts.
What is a Kettle?
the narrow channel carved over time by the water of a stream into sediment or rock layers
What is stream channel?
Only a small portion of precipitation becomes groundwater and is returned directly to the oceans through streams and rivers.
What is false?
__ is the process by which lakes become rich in nutrients, resulting in a change in the kinds of organisms in the lake.
What is eutrophication?
Caused by wind deposition
What is deflation?
Slumps are common after a rainfall because the water
What is reduces friction between soil grains?
Glaciers covered 30 percent of Earth during the last ice age that began about
What is 2.6 million years ago?
the triangular deposit of sediment that forms where a stream enters a large body of water such as a lake or ocean
What is a delta?
ability to transport sediment.
What is the carrying capacity of a stream?
A mound of layered sediment that forms when till gets washed into depressions or openings in melting glacial ice
What is a kame?
