What is the difference between the lithosphere and asthenosphere that makes up the mantle?

• The lithosphere is is a dense solid but the asthenosphere is made of liquid molten metal

• The lithosphere is a mixture of gasses while the asthenosphere is made of solid rock
• The lithosphere is molten rock that moves while the asthenosphere is ridid and thin
• The lithosphere is made of solid rock while the asthenosphere is more flexible hot rock that moves.

Convergent Plate Movement can create

• Rifts
• Mountains
• Ocean Ridges
• Radiation

The _____ core of the earth is made of liquid iron and nickel.

• inner

• upper

• outer

• magnetic

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

• Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

Most tectonic plates have both oceanic and continental crust. How are they different?

• Oceanic is thinner and less dense than continental.

• Continental is thinner and more dense than oceanic.

• Continental is thicker and less dense than oceanic.

• Oceanic is thicker and more dense than continental.

What is CONVECTION?

• The transfer of heat by the movement of a heated solid.

• When heated particles become less dense and rise, then they cool off become more dense and sink.

• The transfer of heat when cold matter rises and heated matter sinks.
