Plate Tectonics

The diagram shows rock layers being pushed up to form a mountain peak.  The arrows indicate the direction of the moving plates.  Which statement identifies the process that might have caused this mountain to form?

• diverging plates and faulting
• converging plates and faulting
• diverging plates and subduction
• converging plates and subduction

Which  distinguishes shield volcanoes from other volcanoes?

• steep slopes and violent eruptions
• gentle slopes and violent eruptions
• gentle slopes and nonviolent eruptions
• steep slopes and non violent eruptions

According to measurements scientists have taken, Earth's crust moves at an average speed of 10 cm per year.  At this speed, approximately how long would it take for plates to move thousands of kilometers?

• tens of years
• hundreds of years
• thousands of years
• millions of years

The diagram shows a part of Earth during an earthquake.  What do the circular lines represent?

• rock layers
• Earth's layers
• seismic waves
• volcanic eruptions

What enables the plates of the lithosphere to move?

• the force of ocean waves
• the activity of earthquakes
• the activity of volcanoes
• the ability of the upper mantle to flow

Over many years, erosion changes a mountain range by making the peaks

• more jagged
• taller
• shift to the east or west
• shorter and rounder

When two plates move away from each other, what type of boundary is it?

• pushing
• sliding
• converging
• diverging

The diagram shos fossils in layers of rock.  The fossils show that the area was once....

• cold and icy
• covered by water
• rocky and mountainous
• populated by dinosaurs

The diagram represents continental plates moving past each other.  As the plates move past each other, what will most likely occur?

• a volcanic eruption
• an earthquake
• a hurricane
• a drought

A fossilized animal skill is shown in the picture below.  WHat is the most likely conclusion about the animal based on ovservations of the fossil?

• It could run very fast
• it was a carnivore
• it traveled in groups
• it had stripes on its skin
