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.

The freezing point of water in Fahrenheit scale

• 0

• 31

• 32

• 33

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

The process of water turning from a gas into a liquid is called?

• evaporation

• condensation

• freezing

• sublimation

Answer explanation

Matter changes between solid, liquids and gases. If you have time study the names of these changes.
