  • Q2
    What flat landform is found on high ground?
    peninslula
    canyon
    plateau
    plain
    60s
  • Q3
    Which is an example of a change in Earth’s surface that takes a long time?
    weathering of rocks in the crust
    dust blowing on a windy day
    soil moved in a flood
    rocks rolling down a mountain
    60s
  • Q4
    Which of the following causes the materials in rocks to change into different materials?
    ice
    chemicals
    temperature changes
    living things
    60s
  • Q5
    What is similar about the way that ice and plant roots cause physical weathering?
    Both scrape rock particles against each other.
    Both get into a crack and can cause the rock to split.
    Both cause rocks to dissolve into sand.
    Both cause rocks to change into different materials.

  • Q6
    What role do living things play in chemical weathering?
    They cause particles of rock, sand, and soil to scrape against each other.
    They weaken the rock by causing it to expand and contract.
    They give off substances that cause rocks to change into different materials.
    They sprout in a crack and cause the rock to separate into smaller pieces.
    60s
  • Q7
    How does moving ice erode land?
    The glacier wears away bits of rock and soil and carries them long distances.
    The glacier deposits bits of rock.
    Ice reshapes the soil under the glacier.
    Rocks stick to glaciers and fall out of them when melting occurs.
    60s
  • Q8
    What is deposition?
    the process by which weathered pieces of rock move about
    when chemicals cause rocks to change into different materials
    when natural forces break rocks into smaller pieces
    the process by which parts of Earth’s surface are built up
    60s
  • Q9
    Which statement is true about deposition?
    Rivers deposit deltas where they flow out of wetlands.
    Deposition is always a very slow process.
    Small particles settle out first and larger particles settle later.
    Wind carries only small particles such as silt and sand.
    60s
  • Q10
    How does gravity cause the rapid movement of rock and soil?
    It rips rocks apart and moves large chunks long distances.
    It dumps large amounts of snow and ice on top of mountains.
    It pulls loosened material down into piles at the bottom of a hill.
    It erodes shorelines and builds up new landforms in their place.
    60s
  • Q11
    What is one way to limit deposition?
    build barriers to stop wind action
    grow trees and plants on hillsides.
    plow hilly fields to form terraces.
    dig built-up material out of waterways
    60s
  • Q12
    How does having plants on a slope help control erosion?
    They trap some of the soil picked up by wind.
    Rain flowing off the leaves forms puddles.
    They provide barriers on hills that slow water speed.
    Plant roots hold the soil in place.
    60s
  • Q13
    What do scientists call a volcano that has not erupted for a long time?
    inactive
    dormant
    extinct
    active
    60s
  • Q14
    What effect did the 1980 eruption of Mount St. Helens have on nearby areas?
    Hot lava flowed into cities built at the base of the mountain.
    Ash collected near the base but had little effect farther away.
    Rocks flew out and landed 24 kilometers away from the mountain.
    Ash covered the surrounding areas, killing trees and wildlife.
    60s
  • Q15
    Where are most volcanoes located?
    along or near where Earth’s moving plates come together
    below the ocean surface along the coasts of continents
    Earth’s lower mantle
    on islands in the middle of the ocean
