Total questions: 25
Worksheet time: 13mins
What factor has the least effect on the weathering of a rock?
climate conditions
compositions of the rock
exposure of the rock to the atmosphere
the number of fossils found in the rock
Which property of water makes frost action a common and effective form of weathering?
Water dissolves many earth materials
water expands when it freezes
water cools the surroundings when it evaporates
water loses 334 joules of heat per gram when it freezes
The action of the root splitting the bedrock is an example of
chemical weathering
deposition
erosion
physical weathering
In which climate would the chemical weathering of limestone occurs most rapidly?
cold and dry
cold and humid
warm and dry
warm and humid
Which type of weathering was primarily responsible for the development of caves?
physical weathering of sandstone
physical weathering of limestone
chemical weathering of limestone
chemical weathering of limestone
Which statement best characterizes the soils found in New York State?
all the soil has been removed by glaciation
wind erosion has been the dominant agent is soil formation
transported soils are similar in composition to underlying bedrock
transported soils are far more common than residual soils
Why will a rock weather more rapidly if it is broken into smaller particles?
the mineral structure of the rock has been changed
the smaller particles are less dense
the total mass of the rock and the particles is reduced
there is more surface area exposed
Which change would most likely cause soil layer to increase in thickness?
a decrease in slope
a decrease in rainfall
an increase in biological activity
an increase in air pressure
Sediment is deposited in a river delta because the
velocity of the river decreases
force of gravity decreases
volume of the river decreases
gradient of the river decreases
A sediment particle transported by a stream over a long period of time will most likely show
a decrease in mass and number of angular edges
a decrease in density and size
an increase in weight and hardness
an increase in volume and number of cleavage patterns
Which agent of erosion is most likely responsible for the deposition of sandbars along ocean shorelines?
glaciers
mass movement
wave action
wind action
which answer correctly represents the process and agent of erosion responsible for rounded sediment?
Process: sandblasting
agent of erosion: running water
Process: abrasion
agent of erosion: wave action
process: land slide
agent of erosion: mass movement
process: deposition
agent of erosion: wind
The chief agent of erosion on Earth is
human beings
running water
wind
glaciers
which material would most likely be carried by a stream traveling at a rate of 40 centimeters per second?
clay, only
boulders, only
sand, silt, and clay
boulders, cobbles, and pebbles
which agent of erosion most likely carried sediment that scratched and polished bedrock surface?
a moving glacier
running water
wave action
wind
which agent of erosion is responsible for cutting most v-shaped valleys into bedrock?
surface winds
running water
glacial ice
ocean waves
As the gradient of a stream increases, the stream's ability to carry sediment
decreases
increases
remains the same
which is the best example of physical weathering?
the cracking of rock caused by the freezing and thawing of water
the transportation of sediment in a stream
the reaction of limestone with acid rainwater
the formation of a sandbar along the side of a stream
For which movement of earth materials is gravity not the main force?
snow tumbling in an avalanche
moisture evaporating from an ocean
boulders carried by a glacier
sediments flowing in a river
Which erosional force acts alone to produce avalanches and landslides?
sea waves
winds
running water
gravity
A glass sphere and a lead sphere have the same volume. Each sphere is dropped into a container of water. Which statement best explains why the lead sphere settles faster?
the lead sphere has higher density
the lead sphere takes up less space
the glass sphere has more surface area
the glass sphere has a smoother surface
the particles in a sand dune deposit are small and very well sorted and have surface pits that give them a frosted appearance. This deposit most likely was transported by
gravity
wind
glacial ice
ocean currents
A state of dynamic equilibrium exists in an erosional depositional system when
the rate of erosion is the same as the rate if deposition
the rate of erosion exceeds the rate of deposition
the amounts of kinetic energy and potential energy both equal zero
all sediments are transported to the sea and erosion stops
Which rock particles will remain suspended in water for the longest time?
pebbles
silt
clay
sand
Which erosional agent typically deposits hills of unsorted sediments?
ocean waves
glaciers
winds
streams
