chapter 27.2 Flashcards
what is the difference between weathering and eruption
breaking down of materials
removal of surface material
if the lope of the river decreases what will happen to the speed of the rive
it will decrease
small streams that flow into rivers are called what
tributaries
land areas that gather water for a major river is called a
drainage basin
a boundary that separates distinct drainage basins is called a blank
drainage basin
as water flows downhill under the influence of gravity water erodes earth surface creating blank
channels
young rivers are blank due to the fast movement
V-shaped
mature
mature rivers are wind with smooth and gentle slopes
what land form is created when when a river flood and drop their sediment load
flood plains
what is a fan shape sediment deposit that was formed at formed at the mouth of a river
deltas
what are distributaries
branching channels created by delta
what are two types of glaciers
valley and continental
where do valley glaciers form
high mouthiness regions
where do continental glaciers from
colder clients occupy large land areas
where are the two continental glaciers located
Greenland and Antarctica
what is cirque
a bowl shaped basins
what is an arete
form where 2 adjacent valley glaciers meet and erode a long sharp ride line
what is a horn in a mountainous region
sharpened peaks
what shape of valley do valley glaciers from
u shaped valleys
what are tributary glaciers
small glaciers that feed into the large glaciers
what type of valleys do tributary glaciers from
on which side of a sand dun does erosion accrue
windward side
which side does deposition occur
leeward side
what is deflation
removal of small participial
what is desert pavement
removal of the remaining surface
the shape and sises of land forms depend on what
wind speed, amount of time the wind, sediment supply
what are three land forms created by wave erosion
coastal cuffs
sea stacks
sea arches
what are two examples of wave definition
sand Bard
sand spits
what are sand bard and spitd
a bar of snad
a snad spit curves back to land
what are some things that can cause mass wasting
snow
heavy rains
earthquakes
human activity
what are some examples of mass wasting
rock slides
mud floes
landslides
