ES. Final Exam Geology

A volcano such as Hawaii or Super volcano that have formed in the middle of a plate have formed due to

• A hot spot
• A divergent boundary
• A convergent boundary
• A transform boundary

Which statement is true about the ocean floor as you move away from the mid-ocean ridge.

• The age and density increase.
• The age and density decrease.
• The age increases while the density decreases.
• The age decreases while the density increases.

What piece of evidence was not used to support Wegener's hypothesis of continental drift?

• Explained how the continents moved.
• Fossil evidence found on separated continents.
• Evidence of climates that changed.

This dangerous volcano alternates between quiet and explosive eruptions and is usually a tall, well-shaped cone. Mt. St. Helens is an example.

• Composite Volcano
• Cinder Cone Volcano
• Shield Volcano
• Fissure

Tectonic plates move because of

• Convection in the asthenosphere (mantle)
• Convection currents in the convective zone
• Convection in the atmosphere.
  
• Seismic waves in the asthenosphere.

Which is true of oceanic crust?

• It's composed of basalt and it is denser than continental crust.
• It's composed of granite and it is denser than continental crust.
• It's composed of basalt and it is less dense than continental crust.
• It's composed of granite and it is less dense than continental crust.

Scientists learned about Earth's interior by

• studying seismic waves
• studying convection currents
• digging deep into the interior.
• studying ocean waves.

Granite has large grained crystals because

• it is an intrusive igneous rock that cooled slowly.
• it is an intrusive igneous rock that cooled quickly.
• it is an extrusive igneous rock that cooled slowly.
• it is an extrusive igneous rock that cooled quickly.
