Plate Tectonics and Mountain Building

According to Wegener's hypothesis of continental drift, 

• Earth's surface is made up of seven major landmasses
• the continents DO NOT move
• Earth is slowly cooling and shrinking
• the continents were once joined together in a single landmass

What type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis?

• evidence from landforms
• evidence from fossils
• evidence from human remains
• evidence from climate

Most geologists rejected Alfred Wegener's idea of continental drift because...

• it did not agree with their current theory
• Wegener was interested in what Earth was like millions of years ago
• Wegener used several different types of evidence to support his hypothesis
• Wegener could not identify the force that moved the continents

What discovery caused scientists to rethink Wegener's continental drift theory?

• discovery of earthquake activity in California
• discovery of the ring of fire in the Pacific Ocean
• discovery of seafloor spreading in the Atlantic Ocean
• discovery of deep trenches off the coast of South America

The Pacific Ring of Fire is an arc around the Pacific Ocean where many volcanoes and earthquakes are formed.

• True

• False

What drives tectonic plate movement? 

• gravity
• coriolis effect
• convection currents
• the earth's magnetic core

What is the difference between the theory of continental drift and plate tectonics?

• They are both the same.

• Plate tectonics explains why Earth's Continents are moving; the theory of continental drift does not.

• Plate tectonics does not explain why Earth's continents are moving; the theory of continental drift does.

• None of the above.

Plates that move apart from each other

• divergent

• transform

• convergent

• lithosphere

Cracks or breaks in earth's crust where plates slip past each other

• subduction

• faults

• mid-ocean ridge

• san andreas

Continental plate collides with another continental plate creates

• volcanoes

• earthquake

• trench

• folded mountains
