MAP Study material for Unit two

What is the definition of convection?

• The process of forming crystals

• The transfer of heat through the movement of fluids

• To move in a regular pattern or series of changes

Fill in the blank: The slow cooling of magma allows for the _______ of minerals.

• crystallization

• melting

• vitrification

• sublimation

What does the term 'cycles' mean?

• The transfer of heat through the movement of fluids

• To move in a regular pattern or series of changes

• The process of forming crystals

The Earth's crust at mid-ocean ridges is formed due to seafloor spreading.

• Formation of new crust by seafloor spreading

• Subduction of crust at plate boundaries

• Crumbling of crust due to earthquakes

• No significant change

At trenches, the Earth's crust is subducted beneath the overriding plate.

• It is subducted

• It is uplifted

• It remains unaffected

• It is eroded completely

Mountains form through plate tectonics.

• Plate tectonics

• Erosion

• Sedimentation

• Meteorite impact

What is the definition of weathering?

• A) The change in shape or size of a material due to stress or force.

• B) The breakdown of rocks, soil, and minerals through contact with the Earth's atmosphere, water, and biological organisms.

• C) The deformation of rocks can lead to the formation of mountains.

What is the definition of deformation?

• A) The change in shape or size of a material due to stress or force.

• B) The breakdown of rocks, soil, and minerals through contact with the Earth's atmosphere, water, and biological organisms.

• C) Wind and rain cause weathering of rocks over time.

Think about a time you saw something change over time, like a plant growing or a puddle drying up. It is similar to the way the Earth's crust changes over time:

• They both change gradually over time

• They both change suddenly

• They both remain the same

• They both only get smaller

Traveling inside the Earth would expose you to its intense heat and constant movement. Which one of the following best describes what you would feel?

• A calm, cool environment

• Extreme heat and seismic vibrations

• A dry, static interior

• An icy, motionless core
