Full solutions for Biology: The Dynamics of Life | 1st Edition
A fine-grained igneous rock of mafic composition.
The first layer of the solar atmosphere found directly above the photosphere.
Continental (c) air mass
An air mass that forms over land; it is normally relatively dry.
The vibration of Earth produced by the rapid release of energy.
The variation of an ellipse from a circle.
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 method of locating stellar objects much like the coordinate system used on Earth’s surface.
An eruption in which lava is extruded from narrow fractures or cracks in the crust.
Solid particles that serve as cores for the formation of ice crystals.
A fossil that is associated with a particular span of geologic time.
A region outside the orbit of Neptune where most short-period comets are thought to originate.
The energy absorbed or released during a change in state.
The brightness of a star. The amount of energy radiated by a star.
A span on the geologic time scale between the eons of the Precambrian and Mesozoic era from about 540 million to 248 million years ago.
The process by which plants and algae produce carbohydrates from carbon dioxide and water in the presence of chlorophyll, using light energy and releasing oxygen.
A lake formed during a period of increased rainfall. During the Pleistocene epoch this occurred in some nonglaciated regions during periods of ice advance elsewhere.
Positive feedback mechanism
A feedback mechanism that enhances or drives change.
The spinning of a body, such as Earth, about its axis.
Ultimate base level
Sea level; the lowest level to which stream erosion could lower the land.
The concept that the processes that have shaped Earth in the geologic past are essentially the same as those operating today
