the amount of mass per unit of volume

A measure of the amount of matter in an object

The amount of space an object takes up

The process in which materials separate and form layers based on differences in density, with denser materials sinking and less dense materials rising

The thin and solid outermost layer of the Earth

the relatively thick part of the earth's crust that forms the large landmasses. It is generally older and less dense than the oceanic crust

thinner, more dense, younger crust making ocean floor; consists of primarily basalt

The layer of hot, solid material between Earth's crust and core.

the liquid layer of the Earth's core that lies beneath the mantle and surrounds the inner core

A dense sphere of solid iron and nickel at the center of Earth

A rigid layer made up of the crust and the uppermost part of the mantle; the tectonic plates are within this layer

The soft layer of the mantle on which the lithosphere and tectonic plates float

Circular currents in the mantle caused by the magma being heated by the core off the Earth

The total energy of motion in the particles of a substance

The transfer of thermal energy by the circulation or movement of a liquid or gas

The direct transfer of heat from one substance to another substance that it is touching.

The transfer of energy by electromagnetic waves

The state of two or more objects or substances in contact when they have reached an equal, common temperature

constructive processes

The geologic processes in which Earth's surface is built up, such as mountain building and volcanism.

destructive processes

The geologic processes in which Earth's surface is broken down, such as weathering and erosion.

The breaking down of rocks and other materials on the Earth's surface; This process "breaks it"

Processes by which rock, sand, and soil are carried away; This process "takes it"

A process in which tectonic plates collide and fold upward to form a mountain range.

A type of rock that forms from compressed or cemented layers of sediment over time.

A type of rock that forms from the cooling of molten rock at or below the surface.

A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.

Question	Answer
density	the amount of mass per unit of volume
