Earth Science Worksheet

A student claims that convection currents within the mantle are similar to the movement of water in a glass placed on a hot stove. Based on the analogy, select the image that correctly represents the movement of the water.

• Image A

• Image B

• Image C

• Image D

What is the flow of matter in the mantle responsible for?

• The flow of matter in the mantle is directly responsible for the movement of the plates that form the Earth's crust.

• The flow of matter in the mantle is responsible for the formation of mountains.

• The flow of matter in the mantle is responsible for the creation of ocean currents.

• The flow of matter in the mantle is responsible for weather patterns.

Which region of the mantle has the highest temperature?

• Region A

• Region B

• Region C

• Region D

Which of these processes results in a chemical change in rocks?

• A. Deposition

• B. Transport

• C. Erosion

• D. Crystallization

The mantle is important for the movement of Earth's plates because:

• Conduction from the core creates strong magnetic fields in the mantle, which help move Earth's plates.

• 
  The pressure from the core creates convection currents in the mantle, which help move Earth's plates.

• 
  Heavy metals in the mantle create strong magnetic fields, which help move Earth's plates.

• 
  Temperature differences in the mantle create convection currents, which help move Earth's plates.

What must be present for metamorphic rocks to form?

• Heat and pressure

• Water and air

• Sunlight and soil

• Ice and wind

What type of rock is formed by the cooling of magma?

• Sedimentary rock

• Metamorphic rock

• Igneous rock

• Limestone

Rocks break down into smaller particles by the process of:

• weathering

• evaporation

• condensation

• sublimation

Mountains are formed by:

• Terrain erosion

• Volcanic activity

• Movements of tectonic plates

• Weathering processes

How does the movement of tectonic plates cause the formation of a volcano at this type of boundary?

• When one tectonic plate collides with another tectonic plate of the same density, the rocky crust is pushed upwards.

• When one tectonic plate slides against another tectonic plate, the energy released travels through the rocky crust in waves.

• When one tectonic plate moves away from another tectonic plate, hot magma rises through the cold crust to form new crust.

• When one tectonic plate moves beneath another tectonic plate, the rocky crust melts, causing hot magma to rise to the surface.
