  • Question 1
    20 seconds
    Q. The natural chemical or physical processes that breaks down rock on Earth's surface.
    answer choices
    weathering
    erosion
    deposition
    jackhammering
  • Question 2
    20 seconds
    Q. The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.
    answer choices
    weathering
    erosion
    deposition
    dumptruck
  • Question 3
    20 seconds
    Q. This type of weathering occurs when rock is physically broken down into smaller pieces of rock.
    answer choices
    mechanical weathering
    chemical weathering
    erosion weathering
    deposition
  • Question 4
    20 seconds
    Q. This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.
    answer choices
    mechanical weathering
    chemical weathering
    erosion weathering
    deposition
  • Question 5
    20 seconds
    Q. These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:
    answer choices
    ice wedging
    chemical weathering
    acid rain
    abrasion
  • Question 6
    20 seconds
    Q. These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:
    answer choices
    ice wedging
    acid rain
    permeability
    abrasion
  • Question 7
    20 seconds
    Q. This rock may chemically weather easily because is has many spaces or holes in it that allow water to seep through it, meaning it is:
    answer choices
    permeable
    abrasive
    erosion
    unchangable
  • Question 8
    20 seconds
    Q. These gravestones have slowly broken down and turned a blackish color due to the action of:
    answer choices
    ice wedging
    abrasion
    acid rain
    mechanical weathering
  • Question 9
    20 seconds
    Q. How might a weathered mountain appear different than an unweathered mountain?
    answer choices
    Weathered mountain would be taller.
    Weathered mountain would be rounder and less jagged.
    Weathered mountain would be more jagged and less rounded.
    Weathered mountain would have no trees.
  • Question 10
    30 seconds
    Q. How is mechanical weathering different from chemical weathering?
    answer choices
    Chemical weathering happens over much shorter time frame than mechanical weathering.
    Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
    Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.
    Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.
  • Question 11
    20 seconds
    Q. Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 12
    20 seconds
    Q. Potholes forming in the road after a cold winter is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 13
    20 seconds
    Q. A metal statue slowly turning green after years of being outside is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 14
    20 seconds
    Q. Rocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 15
    20 seconds
    Q. A piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 16
    20 seconds
    Q. The formation of stalactites and stalagmites in a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the limestone, is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 17
    20 seconds
    Q. The formation of large cracks in the face of a mountain from ice wedging is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 18
    20 seconds
    Q. Acid rain wearing away the face of a marble gravestone or statue is an example of?
    answer choices
    mechanical weathering
    chemical weathering
  • Question 19
    20 seconds
    Q. Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart.  This is an example of:
    answer choices
    mechanical weathering
    chemical weathering
  • Question 20
    20 seconds
    Q. Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:
    answer choices
    mechanical weathering
