Earth Science Test Review - Part 2

Oceanic plates are pushed down into the mantle at

• convection currents

• subduction zones

• strike-slip faults

• divergent boundaries

When tectonic plates collide, molten rock from beneath the crust of the Earth sometimes forces up through to the surface, creating

• a mountain

• an earthquake

• a rift

• a volcano

The most likely cause of earthquake activity on the west coast of the United States is

• landslides from coastal mountains

• slipping of tectonic plates

• tidal effects from the Pacific Ocean

• seasonal temperature changes

Under which of the following headings in a table of contents would the most information about Pangaea be found?

• How to clean and prepare fossil samples

• Alfred Wegener and continental drift

• The movement of glaciers

• All you need to know about the asthenosphere

Which process provides nearly all of the force that drives the movements of the Earth's tectonic plates?

• Combined gravitational pull of the sun and the moon

• centripetal force from the Earth's rotation

• combination of wind and wave action

• convection currents in Earth's mantle

Which type of plate boundary typically causes an oceanic trench?

• tranform

• divergent

• convergent

• elastic

How can scientists obtain direct samples of Earth's mantle?

• Volcanic eruptions can bring melted rock onto the surface that cools into new rock

• Seismic waves that pass through Earth bring mantle rocks to the surface

• Certain meteorites bombard Earth may represent the composition of the mantle

• Volcanic eruptions can bring solid chunks of rock from Earth's mantle to Earth's surface.

Which landform is likely to form where two oceanic plates move apart?

• trench

• mid-ocean ridge

• sand dune

• folded mountain

What hypothesis says that continents were once together and have since moved apart?

• continental drift

• magnetic reversals

• plate tectonics

• subduction

What are tectonic plates?

• large, slowly moving pieces of Earth's lithosphere

• large, slowly moving pieces of Earth's asthenosphere

• large, slowly moving pieces of Earth's mesosphere

• large, slowly moving pieces of Earth's outer core
