Plate Tectonics Review

This was the supercontinent that existed 500 million years ago

• Gondwala

• Pandora

• Pangaea

• Panama

Which of these is NOT an evidence of Pangaea?

• similar landforms across continents

• similar fossils on widespread continents

• similar current climate

• evidence of a similar climate millions of years ago

Who came up with the theory of Pangaea?

• Werner

• Wegener

• Newton

• Darwin

When one layer of crust (usually oceanic) sinks back into the mantle because of differences in density, it is called:

• subtraction

• density

• volcanoes

• subduction

At this type of boundary, plates move away from each other

• convergent

• divergent

• transform

At this type of boundary, plates slide past each other

• convergent

• divergent

• transform

At this type of boundary, plates collide with each other

• convergent

• divergent

• transform

This causes plate tectonics

• conduction in the mantle

• radiation from the Sun

• convection in the outer core

• convection in the mantle

Tectonic plates are made of the:

• lithosphere

• asthenosphere

• mesosphere

• crust

This forms at a divergent boundary on land:

• deep-ocean trench

• rift valley

• mid-ocean ridge

• mountains
