Convection currents in the mantle are driven by changes in the temperature and density of material. Material moving toward the upper mantle must: (select two)

• have increasing temperature

• have increasing density

• have decreasing temperature

• have decreasing density

Convection currents in the mantle are driven by changes in the temperature and density of material. Material moving toward the lower mantle must: (select two)

• have increasing temperature

• have increasing density

• have decreasing temperature

• have decreasing density

Select the two processes that occur at mid-ocean ridges.

• material rises from the mantle to the crust

• sediments from the crust sink into the mantle

• crustal rock subducts into the mantle and melts

• thermal energy rises from the mantle to the crust

• tsunami waves transfer energy from teh crust to the mantle
