Plate Tectonics

This layer of Earth is the thickest part

• crust
• outer core
• mantle
• inner core

Which layer has convection currents?

• Inner Core
• Outer Core
• Mantle
• Crust

What did Wegener observe about the continents that led to his theory of continental drift?

• They were made up of tectonic plates
• They appeared to fit together like a puzzle
• They were moving several meters each year
• They seemed to be sinking into the ocean

What is this image...

• Revolving boundary
• San Andreas (Transform)
• Convergent

What is one piece of evidence used to explain the theory of continental drift?

• The rocks that make up the earth's crust are different on every continent
• There are a variety of animals on different continents
• The same types of fossils appeared on different on every continent
• The mountains on different continent form a pattern

Which best describes the Earth’s mantle?

• The center of the Earth
• Home to all life on Earth
• Thickest layer of hot rock
• Thinnest and hottest layer

The four layers of the Earth from the outermost layer to the innermost layer are:

• inner core, outer core, mantle, crust
• mantle, crust, outer core, inner core
• crust, mantle, outer core, inner core
• crust, outer core, mantle, inner core

The thinnest layer of the Earth is?

• outer core
• inner core
• mantle
• Crust

What is this a picture of?
