People of the Earth: An Introduction to World Prehistory 14th Edition Solutions

A theory that relates the formation of precipitation to supercooled clouds, freezing nuclei, and the different saturation levels of ice and liquid water.

A form of condensation best described as a dense concentration of suspended water droplets or tiny ice crystals.

The gently sloping submerged portion of the continental margin, extending from the shoreline to the continental slope.

One of the two types of dry climate; the driest of the dry climates.

A layer of coarse pebbles and gravel created when wind removed the finer material.

The gradual increase in temperature with depth in the crust. The average is 30° C per kilometer in the upper crust.

A compositional group of igneous rocks that indicates a rock is composed almost entirely of light-colored silicates.

Forming where glacial ice flows into bays, it is a large, relatively flat mass of floating ice that extends seaward from the coast but remains attached to the land along one or more sides.

An atom or molecule that possesses an electrical charge.

A line drawn on a map connecting points of equal atmospheric pressure, usually corrected to sea level.

See Asthenosphere.

Metamorphic rocks that do not exhibit foliation.

Resource that forms or accumulates over such long time spans that it must be considered as fixed in total quantity.

Deposit formed when heavy minerals are mechanically concentrated by currents, most commonly streams and waves. Placers are sources of gold, tin, platinum, diamonds, and other valuable minerals.

A solid celestial body that accumulated during the first stages of planetary formation. Planetesimals aggregated into increasingly larger bodies, ultimately forming the planets.

The minerals that make up most of the rocks of Earth’s crust.

A layer of soil that has identifiable characteristics produced by chemical weathering and other soil-forming processes.

A collective term for breakers; also, the wave activity in the area between the shoreline and the outer limit of breakers.

The turbulent advance of water created by breaking waves.
