Mid-Atlantic Ridge

Subduction

The term for the downward movement of a tectonic plate into the mantle.

Lithosphere

The term for uppermost layer of the mantle that is broken into a number of plates.

Volcanos

A collision between an oceanic and continental plate produces these.

Sea-floor spreading

The term for the process by which the sea floor moves away from mid-ocean ridges.

Plate Tectonics

A theory describing the drifting of continents involving the entire surface of the planet.

Abyssal plain

All of the following were among the early evidence of continental drift EXCEPT

• Similar fossils on opposing coasts of the Atlantic Ocean

• Matching geological formations on either side of the Atlantic Ocean

• Coastline observations from philosopher and writer Sir Francis Bacon.

• Coastline observations from philosopher and writer Sir Francis Bacon.

Marine sediments provide information about Earth's geological past; most marine sediments are the lithogenous and biogenous types.

TRUE

Black smokers

These are the chimney-like structures that gradually build up around a deep-ocean vent due to mineral deposits. 

Hydrothermal vents

After seeping down to the Earth's mantle, heated seawater is forced through the crust as these. 

Mid-ocean Ridge

These are formed when material rising from the Earth's mantle lifts the oceanic crust.

Central rift valleys

As oceanic plates pull apart great gaps or depressions can form, which are more specifically known as these.
