Which of the following best describes weathering?
The process by which rocks are exposed to severe weather
The process by which rocks are formed by heat and pressure
The mechanical or chemical process by which rocks are broken down
The process by which rocks are chemically strengthened due to exposure to heat and pressure
Which is an example of oxidation?
Rust decomposes rocks completely with the passage of time.
Some of the minerals get dissolved in water.
The joints enlarge in size and lime is removed in the solution.
Due to the absorption of water by rocks, its volume increases.
In which of the following climates will chemical weathering be most rapid?
hot and dry
cold and dry
hot and humid
cold and humid
Which of the following is an example of biological weathering?
Freeze-thaw
Wind blowing sand onto a rock
Abrasion due to the movement of glaciers
Plant that grows on the cracks of the rocks
Weak organic acids are produced by the action of the growing root of lichens. These acids react with some minerals in rocks resulting in the decomposition of rocks. How will you classify this process?
Physical weathering
Chemical weathering
Biological weathering through physical means
Biological weathering through chemical compounds
What are the two things that affect the rate of weathering?
rain and ice
type of rock and climate
time and date
size of rock and time of the year
Which of the following best describes chemical weathering?
The process by which rocks are broken down by physical forces
The process by which rocks are broken down by chemical means
The process by which rocks are broken down by anthropogenic activities
all of these
This involves the action of water on minerals.
solution
Hydration
Hydrolysis
The breaking down or dissolving of rocks and minerals on Earths surface.
Transformation
Weathering
Wheathering
Erosion
These processes are more rapid in desert and in the cold environment on high mountains and closer to the poles.
Chemical Weathering
Physical Weathering
Biological Weathering
The process of _______ affects ricks in dry areas, where oxygen is in direct contact with the rocks
exfoliation
carbonation
oxidation
Which type of weathering caused this rock deformation?
Physical (mechanical)
Chemical
Biological
As water freezes and expands, then thaws, forces on rocks continuously change, causing them stress. This weakens the rock over time.
abrasion
ice wedging
acid rain
oxidation
Rocks collide with other materials and sediments. This can happen by wind, water, or gravity.
chemical weathering
abolition
obstruction
abrasion
