Ch. 5 Test review

An area where material from deep inside Earth rises through the crust & melts to form magma.

Part of the ocean floor sinks back into the mantle at:

Mid ocean ridges form long chains of these on the ocean floor.

What does "con"mean?

The process of adding new material to the ocean floor along mountain ranges under water.

Molten mixture of rock forming substances, gases, and water from the mantle on Earth/s surface.

Any trace of an ancient organism that has been preserved in rock.

Heat transfer by the movement of a fluid.

Sea floor spreading begins at a:

Which type of boundary is shown in the middle diagram (letter B)?

Process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle.

Where plates move apart from each other.

Mountain range formed from the seams that run along the middle of some ocean floors.

Along a ridge, new molten material rises to the surface then cools off & hardens to form rock.

The supercontinent when continents were joined together.

The process of forming deep ocean trenches takes:

Deep underwater canyons found in the ocean floor; oceanic crust bends downward here.

The idea that the continents slowly moved over Earth's surface.

Where plates come together.

What does "di" mean?

Which type of boundary creates mountains?

This image is showing the process of:

The flow that transfers heat within a fluid.

This image is showing the process of:

The transfer of energy that is carried in rays like light.

This image is showing the process of:

Where are the youngest rocks near a mid ocean ridge?

Earth's lithosphere is broken into these pieces, separated by cracks.

According to Wegener's theory, which 2 continents fit back together best?

Where are the oldest rocks near a mid ocean ridge?

A mountain that forms on Earth's crust when magma reaches the surface.

This type of boundary mostly occurs along the mid ocean ridges, where seafloor spreading occurs

Which type of boundary is shown in the top diagram (letter A)?

Compression belts form along the boundaries of Earth's plates

According to the theory of plate tectonics,the Earth's plates are in constant motion because of

What happens at a mid ocean ridge?

Which continent / country moved the most from its position in Pangaea to today?

A major belt of volcanoes; includes many volcanoes that rim the Pacific ocean.

What is this image showing?

Which type of boundary is shown in the bottom diagram (letter C)?

At which type of boundary is crust neither created or destroyed?

What do the red arrows in this diagram represent?

Heat transfer between materials that are touching.

What is the red dotted line in the image showing?

Molten mixture of rock forming substances, gases, and water from the mantle.

Which island formed first / is the oldest?

Where plates slip past each other.

What 2 landforms are created at convergent boundaries?

Breaks in Earth's crust where rocks have slipped past each other.

What does "trans"mean?

Who proposed: all continents were once joined in a single landmass, & have since drifted apart?
