Continental Drift & Plate Tectonics

In a tectonic plate demonstration during class, Mrs. Smith

pushes two pieces of modeling clay together. What kind of

plate boundary was the teacher demonstrating?

• Convergent

• Earthquake

• Equator

• Divergent

What is the Theory of Continental Drift?

• New continents are continually being created

  and destroyed.

• The layout of the continents is the same today

  as it has always been

• The continents have always been separate but

  may one day drift together to form a single

  continent

• All the continents were once one continent that

  broke up and drifted apart over hundreds of

  millions of years

Where does magma rise to the top to become new crust?

• one plate splits into two distinct plates

• one plate grinds against another plate

• two plates separate and move apart from one

  another.

• two plates meet and collide with one another.

When crust is neither created nor destroyed, what boundary is it formed along?

• convergent

• divergent

• collisional

• transform

What type of tectonic plate boundary involves a collision of plates?

• transform

• divergent

• convergent

• obstructive

Who came up with the theory of continental drift?

• Harry Hess

• Albert Einstein

• Alfred Wegener

• Bill Nye the Science Guy

How did fossil evidence support Wegener's hypothesis of continental drift?

• Similar fossils are found along continental margins that appear to join together.

• Fossils are found in areas where present-day climate could not have supported the organisms that made the fossils.

• Similar fossils of land-dwelling dinosaurs are found on continents separated by oceans.

• All of the above.
