What is happening at A?

• a mountain is forming

• only subduction is occurring

• only a trench is being formed

• subduction is occurring and a trench is being formed

Geologists obtain indirect evidence about Earth's interior by

• measuring pressure differences at Earth’s surface.

• estimating temperature inside earth.

• directly looking under the many layers

• recording and studying seismic (earthquake) waves

According to Wegener's hypothesis of continental drift,

• Earth's surface is made up of seven or eight major landmasses.

• the continents do not move.

• Earth is slowly cooling and shrinking.

• The continents were once joined together in a single landmass.

What is Pangaea?

• the name of a German scientist

• the name of a supercontinent that existed millions of years ago

• another name for continental drift

• the name of an ancient fossil

Most geologists rejected Alfred Wegener's idea of continental drift because

• they were afraid of a new idea

• Wegener was interested in what Earth was like millions of years ago

• Wegener used several types of evidence to support his hypothesis

• Wegener could not identify a force that could move the continents
