The grinding and scraping of a rock surface by the friction and impact of rock particles carried by water, wind, or ice.
Mass per unit volume of a substance, usually expressed as grams per cubic centimeter
Elements of weather and climate
Those quantities or properties of the atmosphere that are measured regularly and that are used to express the nature of weather and climate.
A coast where land that was formerly below sea level has been exposed either because of crustal uplift or a drop in sea level or both.
A texture of metamorphic rocks that gives the rock a layered appearance.
The change of state from a liquid to a solid.
The view that the Sun is at the center of the solar system.
Law of conservation of angular momentum
The product of the velocity of an object around a center of rotation (axis), and the distance squared of the object from the axis is constant.
The boundary between the mesosphere and the thermosphere.
Mountains acting as barriers to the flow of air, forcing the air to ascend. The air cools adiabatically, and clouds and precipitation may result.
See Jovian planet.
The minerals that make up most of the rocks of Earth’s crust.
A rapidly moving ocean wave generated by earthquake activity capable of inflicting heavy damage in coastal regions.
An instrument that records earthquake waves.
The speed at which a particle falls through a still fluid. The size, shape, and specific gravity of particles influence settling velocity.
The area where an air mass acquires its characteristic properties of temperature and moisture.
A pluton similar to but smaller than a batholith.
The idea that the rifting and dispersal of one supercontinent is followed by a long period during which the fragments gradually reassemble into a new supercontinent.
