Convergent Boundary

What are the two types of crust?

• Convergent and Divergent

• Lithosphere and Asthenosphere

• Continental and Oceanic

• Trench and Island Arc

Why does the oceanic crust sink beneath the continental crust at a subduction boundary?

• The oceanic crust is hotter

• The oceanic crust has a greater density

• The oceanic crust has a lighter density

• The oceanic crust has more magnetic composition

What will happen to the leading edge of the subducted denser plate?

• It will reach the mantle, causing it to melt and turn into magma

• It will reach the mantle and evaporate

• Volcanic arc will form

• It will generate a tsunami

The type of plate boundary where two plates come together is a .....

• Convergent Boundary
• Divergent Boundary
• Transform Boundary
• Plate Boundary

Volcanoes and Earthquakes typically occur _______________.

• along plate boundaries

• only under water

• only in hawaii

• where it is usually hot

Which of the following causes Earth's tectonic plates to move?

• Energy from the Sun
• Magnetic Pole Reversal
• Convection currents in the mantle
• Faults in Mountain Ranges

The process by which one plate is forced under another

• Radiation

• Convection

• Conduction

• Subduction

Why is there a trench in the water?

• Because of the basalt

• Because of the melting oceanic crust

• Because the oceanic plate is subducting making a deep hole

• Because the oceanic plate is stuck and folds downward
