Why do we have earthquakes?

• fast moving groundwater causes the ground to shake

• violent wind and rains shaking the ground

• the movement of tectonic plates that release energy

• erosion moving rocks and soil

Mid-ocean ridges, rift valleys, and trenches are thought to

• mark the boundaries between tectonic plates.

• reverse roles in the Southern Hemisphere.

• occur in the middle of tectonic plates.

• have no relationship to plate tectonics.

Convection currents in the mantle influence crustal movement is evidence for which theory?

• The theory of convection currents

• The theory of continental drift

• The theory of scientific law

• The theory of plate tectonics

Why is the sea floor spreading?

• crustal plates sinking due to density differences

• new rock forming between two crustal plates at a mid-ocean ridge

• deep ocean currents forcing crustal plates apart

• water pressure is creating a whole in the bottom of the sea
