Continental Drift, Seafloor Spreading, Plate Boundaries

The theory that says Earth's continents once made up an ancient supercontinent, and have been drifting apart ever since:

A divergent boundary occurs when two plates:

Volcanic islands can form from magma which is pushed up at a __________ plate boundary that is colliding.

What causes the tectonic plates to move?

Which picture of Earth is the YOUNGEST?

Which of these is NOT a piece of evidence to support the Theory of Continental Drift?

What type of boundary creates mountains?

What type of boundary is this creating volcanoes?

What type of boundary is this where the plates start out moving TOWARDS each other and then subducting?

Which area of the oceanic crust is the oldest?

What piece of technology helped Harry Hess discover that the sea-floor was not flat?

Where is the oldest rock found on the seafloor where seafloor spreading occurs?

What type of boundary creates trenches?

This type of boundary creates _________ when the sliding occurs.

Remains of warm-weather plants in arctic areas were evidence used to support continental drift.

What is the name of the giant landmass that was formed when all of the continents were attached

What kind of plate boundary is shown here where two plates are sliding past each other?

What kind of plate boundary can play a role in creating a fault?

The idea that these same fossils were found on difference continents is evidence of:

Who discovered and found evidence to support the idea of continental drift?

How is it possible for new crust to be formed during seafloor spreading without increasing the area of the Earth?

Which area of the oceanic crust is the youngest?

The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle
