What is the deepest place on Earth?

• Mount Everest

• Victoria Falls

• The Grand Canyon

• The Mariana Trench

How deep is the Mariana Trench?

• Nearly five miles

• Nearly three miles

• Nearly seven miles

• Nearly ten miles

What would happen if you submerged the world's tallest mountain into the Mariana Trench?

• It would be completely above water

• It would be nearly a mile and a half underwater

• It would be completely submerged

• It would be at sea level

What are the two kinds of tectonic plates?

• Oceanic and Continental

• Igneous and Sedimentary

• Volcanic and Seismic

• Mantle and Crust

What happens when a continental plate and an oceanic plate crash into each other?

• The continental plate slips under the oceanic plate

• The oceanic plate slips under the continental plate

• Both plates merge together

• Both plates are destroyed

What is the process called when an oceanic plate is pushed down underneath a continental plate?

• Convergence

• Divergence

• Subduction

• Seafloor spreading

What is created at divergent boundaries between oceanic plates?

• Deep ocean trenches

• Mid-ocean ridges

• Earthquakes

• Volcanoes

What is the process called when magma rises up to fill the empty space between separating oceanic plates?

• Plate tectonics

• Convergence

• Seafloor spreading

• Subduction

What type of rock is formed from the magma that wells up during seafloor spreading?

• Limestone

• Igneous rock

• Metamorphic rock

• Sedimentary rock

What are mid-ocean ridges made of?

• Shale

• Basalt

• Granite

• Sandstone
