true or false

true
the amount of sediment that a river carries is its
load
which one(s) are true:
a. gravity and the force of the water cause sediment to move downstream

gentle slope
shallow streambed
boulders in streambed
what is flow
volume of water that moves past a point on a river in a given time
what is friction
force that opposes the motion of one surface across another
what is turbulence
movement of water every which way instead of downstream
true or false
where a river flows in a straight line, the water flows faster along the river's sides than near the center
false
what glacial landform is mounds or ridges of till

AND
is is a result of erosion or deposition
moraine

deposition
what is a horn?

and is the result due to erosion or deposition
a sharpened peak

erosion
what is a cirque

and is the result due to erosion or deposition
a bowl shaped hollow

erosion
what is kettle lake

and is the result due to erosion or deposition
small depressions formed when a block of ice melts in till

deposition
what is glacial lake

and is the result due to erosion or deposition
large lake in large basin eroded by plucking and abrasion

erosion
what is arete

and is the result due to erosion or deposition
sharp ride separating cirques

erosion
what is drumlin

and is the result due to erosion or deposition
a long mount of till that is higher at one end

deposition
a glacier picks up rocks through a process called
plucking
times when continental glaciers cover large parts of Earth's surface are called
ice ages
A _______ is any large mass of ice that moves slowly over land
glacier
the sediments deposited directly by a glacier are called
till
which are true about the energy in waves?
it comes from wind
it moves water particles up and down
it moves water particles forward
it moves across the water
it comes from wind
it moves water particles up and down
it moves across the water
what part of the water is affected by a wave in deep water
a wave only effects the water near the surface
which are true about a wave approaching land
a. it begins to drag on the bottom
b. it encounters more friction
c. it speeds up
d. it moves the water toward the land
a. it begins to drag on the bottom
b. it encounters more friction
c. it moves the water toward the land
true or false
waves are the major force of erosion along coasts
true
list two ways that waves erode land
impact and abrasion
part of the shore that sticks out into the ocean because it is made of harder rock is called ____
headland
list three landforms created by wave erosion
sea arch
sea cave
wave cut clif
an area of wave washed sediment along a coast is a
beach
the process in which beach sediment is moved down the beach with the current is called
longshore drift
how does a spit form
by a beach the projects like a finger out into the water
by a beach the projects like a finger out into the water :D
what is a tributary
a stream that flows into a larger stream
what forces pulls objects to earth
gravity
what is glacial erosion
Plucking and ABRASION =)
why do allevial fans form
they form because a stream flows out of a steep, narrow mountain valley and the stream suddenly becomes shallower and wider and creates a fan like appearance
why do sediments move down a beach
because of Longshore Drift
waves erode the land by ____ and _____
impact and abrasion
what is a stream
a channel through which water is continually flowing downhill
what is a load
the amount of sediment a river/stream carries
what is creep
the very slow downhill movement of rock and soil. it can even occur on gentle slopes
EX: Gravestones and fenceposts tilting at odd angles =$
what is moraine
a ridge formed by the till and deposited at the edge of a glacier
explain runoff
runoff is water that flows over the surface of the land rather than soaking into the ground

meander is a looplike bend in the course of a river. It forms byt he river widening from side to side and it tends to erode the outer bank and deposit sediment on the inner bankof a gend
how does an oxbow lake form
an oxbow lake forms as a river floods. during the flod, high water find a straighter route downstream. as the flood waters fall, sediments dam up. the ends of a meander......
