Plate Tectonics

A plate boundary where two plates move away from each other is called

• Divergent Boundary
• Convergent Boundary
• Transform Boundary
• Subduction

Scientists hypothesize that a super continent existed 200 million years ago.  This continent is called

• America
• Super Earth
• Pangea
• Eurasia

A Plate Boundary where two plates move toward each other is called

• Convergent Boundary
• Divergent Boundary
• Transform Boundary
• Subduction

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

• The lithosphere is ismade of dense solid meal whle 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

_______________ Currents within the mantle cause the earth's plates to move and shift s molten material rises and falls due to density and gravity

• Convection
• Radiation
• Conduction
• Wind

Divergent Plate movement can create

• Convection Currents
• Conduction
• Mountains
• Rifts and ocean ridges

When pressure builds between two tectonic plates, it can suddenly release causing a (an) ______________________

• Earthquake
• Volcano
• Convection Current
• Gravitational Pull

The movement of metals within the earth's outer core cause a ____________________________ that is detectable on the earth's surface using a compass

• Gravitational Pull
• Volcanic Eruption
• Magnetic field
• Convection Current

Earth's plates meet at ____________.

• plate tectonics

• plate boundaries

• continental drift

• oceans
