What do you call the process where one plate goes under another plate?

• convection

• conduction

• sublimation

• subduction

Answer explanation

Subduction is where one plate slides under another. In the process, the subducted plate or crust gets melted and the magma is returned to the mantle. Eventually the magma surfaces in a volcano often at the mid-ocean ridge where it forms new crust.

Density of water? (2 answers- pick both)

• 1 gram

• 1 cm3

• 1 g/cm3

• 1 g/ml

Answer explanation

Most important relationship is between the cubic centimeter and the milliliter. They have the exact same volume. The cubic centimeter (cm3) is used when describing the volume of solids. The milliliter (ml) is used to describe the volume of liquids.

The two measurements needed to calculate the density of a substance

• length and width

• mass and volume

• area and mass

• area and volume

• nucleus, cell membrane and vacuole

• fermions, quarks and leptons

• protons, electrons and neutrons

• bosons, photons and gluons

The red lines with the hash marks represent the MID-OCEAN RIDGE. What is happening here?

• the ocean floor is being destroyed

• New Ocean floor is being created

• Nothing is happening

Answer explanation

The mid-ocean ridge is an underwater chain of mountains that circles the earth. Along the ridge there are constant volcanic eruptions that creates new crust.
