Background extinction rate

The relatively constant rate at which species become extinct over the course of geologic time.

Biological diversity (biodiversity)

A measure of the number of different species of organisms in a specific area.

Climate change: A long-term significant change in the weather patterns of Earth.

The oil before it has been refined and made into gasoline and other products.

The increasing variety of species in a system.

Tangible materials, such as timber and food, produced by natural systems, that are essential to human life, economies, and cultures.

The functions and processes that occur in natural systems, such as pollination, that support or produce ecosystem goods and help sustain human life, economies, and cultures.

The legal status of a plant or animal species that is in danger of becoming extinct.

The death of all members of a species or other taxa.

A major decrease in the number of species on Earth in a relatively short period of time.

The remains of a plant or animal preserved in rock, another geological deposit, or petrified.

Damaging a habitat to the extent that it cannot meet the needs of organisms that live and meet their needs there.

An acronym for the phrase, “habitat destruction, introduced species, pollution, population growth, and overexploitation.”

The extinction of many species at the same time.

Large animals with long lifespans.

Fossils that are very small and usually must be studied using a microscope.

Organisms that were not originally found in an area, but were transported there through human activity.

Paleontologist: A scientist who studies Earth’s past by looking at fossils.

The geologic era that began 1.8 million years ago and ended about 12,000 BCE, often called the “ice age” because it was characterized by cold periods accompanied by widespread glaciers.

Sedimentary layers: Compacted and “cemented” hard beds or strata of rocks, typically formed where small pieces of minerals and rocks are deposited over a very long time.
