Chapter 27.2 Flashcards
What is the difference between weathering and erosion
Erosion is the removal of surface material and weathering is the breakdown of materials
If the slope of a river decreases, will the speed of the river decrease too
Yes
What are small streams that flow into larger rivers
tributaries
what is the land area called that gathers water for a major river
drainage basin
What is the boundary that separates distinct drainage basins
drainage divide
As water flows downhill due to gravity, water erodes earth’s surface creating what
channels
young rivers create what shape due to fast movement
V-shape
what types of rivers are wide with smooth and gentle slopes
mature
When river flood and drop their sediment load, which type of land form is formed
flood plains
What are the fan shape sediment depots that form at the end of the river
deltas
What are distributaries
They are branching channels created by deltas
What forms when a river or stream enters into dry land
alluvial fans
What are the 2 types of glaciers
Valley and Continental
Where do valley glaciers form
form in high mountainous regions
Where do continental glaciers form
Ice sheets that occupy large land areas in colder climates
Where are the 2 continental glaciers located
Greenland and Antarctica
What are Cirque
Bowl shaped basins
How do arete’s form
form where 2 adjacent valley glaciers meet and erode a long, sharp ridgeline
What is a horn within a mountainous region
sharpened peeks
what shape of valleys do valley glaciers create
U-shaped valleys
what is a tributary glacier
small glaciers that feed into the large glaciers
what types of valley do tributary glaciers create
hanging valleys
On which side of the dune does erosion occur
windward
On which side of a dune is sediment deposited
leeward
What is deflation
the removal of small particles by win, leaving heavier particles behind
What is it call when small particles are removed then remaining hard surface left behind
desert pavement
What does the shape and sizes of land forms due to wind depend on
wind speed, amount of time the wind blows, sediment supply
What are some land forms created by wave erosion
coastal cliffs, sea stacks, sea arches
What are 2 examples of wave deposition
Sand bars, and sand spits
what is a sand bars
land form that is parallel to the shoreline
what are sand spits
sand bars that extend into the water from land and curve back toward the land in a hook shape
what can cause mass wasting
snow, human activity, earthquakes, and heavy rain
what are some examples of mass wasting
mud flows, rock slides, landslides
