chemical weathering
thermal expansion
biotic weathering
Which of the following includes an example of chemical weathering and an example of physical weathering?
ice wedging and thermal expansion
acid rain (carbonation) and oxidation
oxidation and biotic weathering

Which of the following is NOT a cause of erosion?
gravity

water
wind
How might air pollution affect ancient marble stone monuments that are located in highly polluted cities?
Air pollution causes CO2 and water to mix forming carbonic acid. This leads to acid rain, which leads to faster chemical weathering of the marble.
Air pollution causes more acid rain, which leads to faster physical weathering of the marble.
Air pollution causes more acid rain, which leads to faster deposition of sediments on the marble.
Air pollution has no effect on weathering of rock.
What is gravitational erosion or mass movement?
A process that causes chemical weathering.
A process that causes rock to oxidize.
A process that causes the sediments to break due to heating and cooling.
A process that moves sediments downhill.
Which of the following is the process in which sediment, soil, and rocks are added to a landform by being dropped or placed down such as in a delta or sand dune.
weathering
erosion
deposition
thermal expansion
What force causes all types of mass movement?
Gravity, it pulls sediments downhill.
Acid rain, it causes chemical weathering that breaks down rock.
Unstable slope, it causes landslides.
Mudslide, it transports sediments downhill.
What is carbonic acid (carbonation) and how does it affect rock?
It forms when water combines with calcium carbonate. It can dissolve limestone but not marble.
It forms when water combines with carbon dioxide. It can dissolve rocks such as limestone and marble.
It forms when water combines with carbon monoxide. It can dissolve rocks such as limestone and marble.
It forms when water combines with calcium carbonate. It can dissolve rocks such as limestone and marble.
What causes water to deposit sediments to form deltas?
Water deposits sediments when a river's water slows down as it nears a larger body of water, causing a delta to form.
Water deposits sediments as it rains near the opening of rivers. The rain carries the sediments uphill to form deltas.
Water deposits sediments when water speeds up, causing faster water erosion. This can lead to land slides forming deltas.
None of the above
What happens when a stream slows down?
The stream picks up larger particles of sediments.
The stream has more energy causing more erosion.
The stream picks up more sediments.
The stream deposits sediments.
Landslides, rockfalls, and mudslides are all responsible for both erosion and deposition. What force is mainly responsible for the erosion and deposition that happens in landslides, rockfalls, and mudslides?
Magnetism
Temperature
Wind
Gravity
Which of the following is a type of mass movement?
sand dune
wave erosion
glacier
mudslide
In places in the Chihuahuan Desert in Texas where there is loose sand and strong winds, the wind can pick up the sand and carry it. When the wind slows, it deposits the sand. Which of the following is formed as the wind slows?
sand dunes
glaciers
rockfalls
mudflows
What type of weathering is caused by the repeated heating of rock during the day and cooling during the night?
carbonation
oxidation
thermal expansion
biotic weathering
