What do we call the process in which rock is broken down by changes in its chemical makeup.
Chemical weathering
Mechanical weathering
Erosion
Deposition
The grinding/scratching away of rock by other rock particles carried in water, ice, or wind
Frost wedging
Exfoliation
Oxidation
Abrasion
Plants/animals digging under ground with roots or claws to break apart rocks.
Frost wedging
Abrasion
Burrowing
Exfoliation
A type of chemical weathering in which a substance combines with oxygen, as when iron oxidizes, forming rust.
Acid rain
Oxidation
Reaction to water
Exfoliation
The image above depicts the effects of chemical weathering breaking down limestone. Which type of chemical weathering causes this reaction?
Acid rain
Oxidation
Exfoliation
Abrasion
Over millions of years, the shape of mountains on Earth's surface can change to low hills and then rolling plains. These changes are most likely caused by-
Folding and faulting
Volcanoes and Earthquakes
Human activity
Weathering and Erosion
Which type of sediment does wind erosion most strongly affect?
Loose, sandy soil
Wet rocks
Wet, compacted soil
Dry, compacted soil
Which type of area is more likely to weather and erode? An area with a lot of vegetation (plants) or an area with very little? Why?
The area with very little vegetation, because the roots won't be able to burrow through the rocks to weather it down.
The area with a lot of vegetation, because the roots will burrow through the rocks causing a landslide.
The area with very little vegetation, because it has not roots to absorb extra water or hold the soil together. The extra water and loose soil is likely to become a landslide/mudslide.
The area with a lot of vegetation, because the roots will absorb any extra rain water, and will also hold the soil together preventing a landslide.
Which of the following agents is the usually responsible for the formation of canyons?
Gravity pulling
Wind blowing
Flowing water
Glaciers moving
Deforestation is to do with ...
trees
land
water
air
What is the land used for when it is cleared of trees?
Farming
Fishing
What harmful gas does the rainforest help to get rid of from our atmosphere?
Nitrogen
Oxygen
Carbon Dioxide
Soil erosion is when the soil is not held together and it is washed away by the rain and water. It can cause flooding and landslides.
True
False
