Review earth s surface relief features

Review: Earth’s Surface Relief Features

  • What order of relief is represented by a hill behind your house?

    • first

    • second

    • third

    • fourth

    • none of the above


Review earth s surface relief features1

Review: Earth’s Surface Relief Features

  • What order of relief is represented by the Canadian Rockies?

    • first

    • second

    • third

    • fourth

    • none of the above


Review crustal deformation processes

Review: Crustal Deformation Processes

  • Which of the following is incorrect regarding what happens when compressional and tensional forces are applied to rocks?

    • Folding can occur.

    • Thinning can occur.

    • Faulting can occur.

    • Subduction can occur.


Review crustal deformation processes1

Review: Crustal Deformation Processes

  • A fault created when rocks are pulled apart from one another is a

    • normal fault.

    • reverse fault.

    • thrust fault.

    • strike-slip fault.

    • thinning fault.


Review crustal deformation processes2

Review: Crustal Deformation Processes

  • The fault depicted is a

    • normal fault.

    • reverse fault.

    • thrust fault.

    • strike-slip fault.

    • thinning fault.


Review orogenesis

Review: Orogenesis

  • Which of the following is true of orogenies?

    • Most mountain ranges are the result of a single orogeny.

    • Orogenesis continues today in many of the world’s ranges.

    • A collision between two continental plates is required for an orogeny.

    • Orogenesis generally creates volcanoes but not fault-block mountains.


Review earthquakes

Review: Earthquakes

  • Which of the following most accurately explains the origin of earthquakes?

    • Cracks form in the surface as Earth’s crust cools.

    • Radioactive decay within the mantle creates explosions.

    • Volcanic magma moves suddenly within Earth.

    • A fault builds up strain until it finally moves, releasing energy.


Review volcanism

Review: Volcanism

  • Which type of volcanic eruption consists of large volumes of lava and massive landforms?

    • explosive

    • effusive

    • subductive

    • extrusive
