PLATE TECTONICS

Multiple Choice

Who proposed the idea of Seafloor Spreading?

• Alfred Wegener

• Harry Hess

• Alfred Einstein

• Prince Harry

Multiple Choice

What features form when plates collide at some plate boundaries?

• Mountains and earthquakes

• Mid ocean ridges

• tsunami

• drift

Multiple Choice

Where are the youngest rocks in the ocean found?

• basins

• trenches

• Mid ocean ridges

• volcanoes

Multiple Choice

What is the cycle of rising, cooling and sinking called?

• subduction

• conduction current

• convergent boundary

• convection current

Multiple Choice

What is the name that Alfred Wegener came up with that means "All Land?"

• Pancakes

• Panama

• Pangea

• Pancreas

Multiple Choice

What is the hypothesis that continents have moved slowly to their current locations called?

• Continental Drift

• Continental slope

• magnetism

• convection

Multiple Choice

How fast do the plates on earth's crust move?

• 1 millimeter per year

• 1 Meter per year

• 1 Kilometer per year

• 1 centimeter per year

Multiple Choice

A break in the Earth's Crust usually a site for earthquakes

• fault

• continent

• ridge

• mountain

Multiple Choice

Studying the ocean floor, scientists found rocks showing magnetic

• Bonds

• weakening

• poles

• reversal

Multiple Choice

Why does seafloor spreading occur?

• New material is being added to the athensphere

• earthquakes break apart the ocean floor

• sediments accumulate on the ocean floor

• Hot, dense material below Earth's crust rises up to the surface

Multiple Choice

Which one is the "inner mantle?"

• lithosphere

• megasphere

• asthenosphere

• stratosphere

Multiple Choice

What is the "outer mantle?"

• lithosphere

• megosphere

• athenosphere

• stratisphere

Multiple Choice

Large sections of Earth's crust and upper mantle

• asthenosphere

• Plates

• divergent

• convection current

Multiple Choice

Earth's curst and part of the mantle are broken down into plates that move around on a plastic like layer of the mantle

• divergent

• convergent

• plate tectonics

• pangea

Multiple Choice

Plate boundaries that move toward each other?

• convergent boundaries

• divergent boundaries

• transform boundaries

• fault boundaries

Multiple Choice

When two plates meet one bends and slides under the other

• divergent boundary

• tuck and roll

• subduction

• transform

Multiple Choice

Plate boundaries that move away from each other

• convergent boundaries

• divergent boundaries

• transform boundaries

• subduction

Multiple Choice

What observation led Alfred Wegener to develop his hypothesis of "Continental Drift?"

• He saw seafloor spreading when he was scuba diving

• He used sonic waves and found mountains on the bottom of the ocean floor

• He noticed that rocks were magnetic

• He noticed on a map that the pieces fit together like a puzzle and found similar fossils on multiple continents

Multiple Choice

Label the layers of Earth's crust

• A. crust B. mantle. C. outer core D. inner core

• A. inner core B. outer core C. mantle D. crust

• A. Crust B. inner core C. outer core D. Mantle

• A. Crust B. Mantle C. inner core D. outer core
