[Quiz] Heat Flow Within Earth

What is the definition for outer core?

• made mostly of liquid iron and nickel.

• the slowly flowing layer of rock under the lithosphere

• mostly made of silicate materials

• primarily responsible for convection currents that drive earthquakes

What is the definition for mantle?

• made up of basalt and granite and is the thinnest layer

• the outer portion of the core made mostly of liquid iron and nickel

• the layer of rock between Earth’s outer core and crust in which most rock is hot enough to flow in convection currents; Earth’s thickest layer.

• the layer of Earth made up of the crust and the rigid rock of the upper mantle, averaging about 40 kilometers thick and broken into tectonic plates.

What is the definition for convection?

• the slowly flowing layer of rock under the lithosphere; composed of part of the mantle.

• The transfer of energy from place to place by the motion of heated gas or liquid; in earth’s mantle, convection is thought to transfer energy by the motion of semi-solid rock, which when under great heat and pressure can move like a liquid.

• a measurement of heat in a substance; related to the energy of the particles; how hot or cold something is.

• a thin outer layer of rock above a planet’s mantle including all dry land and oceanic basins. Earth’s continental crust is 40 kilometers thick on average and oceanic crust is 7 kilometers thick on average.

Earth is composed of four layers.

Scientists believe that as the Earth cooled, the denser materials sank to the center and the less dense materials rose to the top. The least dense layer is the...
