What is the promary reason that continents are found at higher elevations than then ocean floor?

• Continental crust is less dense than the oceanic crust

• Continental crust is more dense than the oceanic crust

• Continental Crust covers less surface area than the oceanic

• Continiental Crust covers more surface area than the oceanic crust.

Which statement describes a seismic wave during an earthquake?

• The waves changes direction based on gravity

• the wave changes speed as it moves through the different layers

• the wave loses energy to the oceans when it comes in contact with the water

• the wave reflects off the surrounding rocks as it moves through the outer core.

Why do earthquakes and volcanoes occur at plate boundaries?

• Temperatures are lower near the boundaries

• Tectonic plates remain stationary (still) at plate boundaries

• Temperatures are higher near plate boundaries

• Tectonic plates move past each other at plate boundaries
