Geologic Changes - Ch. 7 plate tectonics

Tectonic plates consist of

• continental crust

• mesospheric crust

• both continental and oceanic crust

• oceanic crust

Which layer of the Earth consists of tectonic plates?

• asthenosphere

• mantle

• mesosphere

• lithosphere

The fact that similar fossils are found on both sides of the ocean is evidence of

• magnetic reversal

• global positioning

• continental drift

• oceanic drift

Who is the scientist who proposed Continental Drift Theory?

• Albert Einstein
• Alfred Wegener
• Isaac Newton
• John Dalton

Alfred Wegener named his single supercontinent ____________, which means "all Earth" in ancient Greek.

• Pandora

• Gandowandaland

• Pangea

• Percia

Associated with transform boundaries.

• Volcanoes
• mountains
• trenches
• earthquakes

A location where two tectonic plates collide is known as a _________ boundary.

• Convergent
• Divergent
• Transform
• Spreading

Subduction means.....

• one plate goes under another plate

• two plates slide past each other

• two plate collide and form folded mountains

Sea-floor spreading explains how.....

• new crust is created at a divergent boundary

• volcanoes are formed on continents

• deep sea trenches are formed

What type of event will occur at this boundary?

• Earthquake
• Volcano Eruption
• Tornado
• Mountain Building
