Continental drifts and moving plates, dynamic Earth

The area of the ocean floor that lies between the shoreline and the abyssal ocean floor, and includes the continental shelf, slope, and rise, is known as:

• Subduction zone

• Continental margin

• Plate boundary

• Mid-ocean ridge

A break in the lithosphere along which bodies of rock can move is referred to as a:

• Convection current

• Tectonic plate

• Fault

• Mantle

The type of rock that forms when hot liquid magma or lava cools and solidifies is called:

• Metamorphic rock

• Sedimentary rock

• Igneous rock

• Asthenosphere

What term describes rocks that are transformed by heat and pressure without melting?

• Igneous rock

• Metamorphic rock

• Continental crust

• Tectonic plate

A long elevated region of the ocean floor with a central valley running along its top is known as a:

• Subduction zone

• Mid-ocean ridge

• Continental drift

• Core

The theory that explains how earth's surface is made of separate plates that move and cause geologic features like earthquakes, volcanoes, and mountains is called:

• Plate tectonics

• Continental drift

• Subduction

• Asthenosphere theory

Sections of the lithosphere that move slowly over the surface of the earth are called:

• Convection currents

• Mid-ocean ridges

• Tectonic plates

• Continental margins

The theory that the continents were once connected in a single large landmass and have since drifted apart is known as:

• Plate tectonics

• Continental margin theory

• Mid-ocean ridge theory

• Continental drift

The upper part of the Earth's mantle, which allows tectonic plates to move, is called the:

• Core

• Lithosphere

• Crust

• Asthenosphere

The process in which heat is transferred through the movement of matter, such as in the mantle, is called:

• Subduction

• Convection

• Continental drift

• Plate tectonics
