1
When the speed of a stream increases, what happens to the size of the sediment it can carry?
stays the same
increases
decreases
2
What causes a sinkhole to occur?
chemical weathering of limestone
physical weathering of sandstone
physical weathering of limestone
chemical weathering of sandstone
3
What is this called?
A river bed
A field
A river delta
A beach
4
What is the difference between physical and chemical weathering?
one uses wind to break apart monuments
one changes the chemical composition of the material
they break down rocks into sediment
5
What caused this to happen?
chemical weathering
physical weathering
lightning strike
6
What type of climate would chemical weathering occur the most?
warm and dry
warm and humid
cold and dry
cold and humid
7
A landslide is an example of:
chemical weathering
mass movement
glacial scouring
river deposition
8
What is it called when a stream deposits sediment from large to small?
unsorted sediments
horizontal sorting
sand deposits
glacier deposits
9
When a stream or the wind slows down and sediment falls out, it is called:
deposition
weathering
erosion
mass movement
10
If the temperature goes from cold to hot over and over, it is called:
chemical weathering
frost action
deposition
erosion
11
When a stream starts to curve over time, it is called:
oxbow lake
deposition
meander
erosion
12
What is this called?
horizontal sorting
erosion
vertical sorting
weathering
13
Is the outside of the curve on the left or right?
right
center
left
14
A stream's velocity decreases from 100 cm/s to 5 cm/s. Which sediments will still be moved?
pebbles, sand, silt, and clay
clay only
sand, silt, and clay only
silt and clay only
15
Sediment that is broken off a cliff and deposited by a landslide will be:
rounded and sorted
rounded and unsorted
sharp and sorted
sharp and unsorted
16
What is weathering?
when sediments fall to the ground
the breaking down of rock into sediment
when climate changes rapidly
the movement of rocks from one place to another
17
What side did deposition occur?
Right
Center
Left
18
What is the minimum water velocity needed to move a particle 0.1 centimeter? (Use page 6!)
5 cm/s
0.5 cm/s
0.02 cm/s
20.0 cm/s
19
Why are craters more visible on the moon than on Earth?
meteorites have not struck Earth
all meteorites burn up in Earth's atmosphere
Earth is younger than the moon
weathering processes on Earth have removed most craters
20
Which of these is a characteristic of a rock that has been in a stream for a long time?
rough
large
sharp with angles
smooth
21
What is erosion?
when sediment falls to the ground
when a stream starts to curve through a landscape
the movement of sediment from one place to another
22
When a tree root spits apart the sidewalk, this is an example of:
chemical weathering
erosion
deposition
physical weathering
23
Which sample has gone through the most abrasion in a stream?
B
C
D
A
24
What is the biggest particle of these?
pebbles
clay
boulder
sand
25
Sediment is deposited in a river delta because the:
volume of the river increases
force of gravity decreases
gradient of the river increases
velocity of the river decreases
26
When a stream curves, which of these occurs on the outside of the curve?
erosion
deposition
weathering
27
What are two things that affect the rate of stream erosion?
stream velocity and gravity
the weather and climate
wind and gravity
