Fossil Fuel

Question 1

Unitarianism

Answer 1

the theory that changes in the earth’s crust during geological history have resulted from the action of continuous and uniform processes.

Question 2

catastrophism

Answer 2

the theory that changes in the earth’s crust during geological history have resulted chiefly from sudden violent and unusual events.

Question 3

paleontology

Answer 3

Paleontology is the scientific study of life in the geologic past, based on examination of fossilized remains of once living organisms, such as tracks, bones, teeth, plants, and shells.

Question 4

relative dating

Answer 4

Relative dating is the process of determining if one rock or geologic event is older or younger than another, without knowing their specific ages

Question 5

absolute dating

Answer 5

Absolute dating methods measure the physical properties of an object itself and use these measurements to calculate its age.

Question 6

superposition

Answer 6

Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured.

Question 7

isotope

Answer 7

each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

Question 8

radioactive decay

Answer 8

Radioactive decay is the process in which a radioactive atom spontaneously gives off radiation in the form of energy or particles to reach a more stable state.

Question 9

half-life

Answer 9

The time required for a biological system, such as that of a human, to eliminate, by natural processes, half of the amount of a substance (such as a radioactive material) that has entered it.

Question 10

fossil

Answer 10

the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.

Question 11

trace fossil

Answer 11

a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself.

Question 12

mold

Answer 12

a hollow container used to give shape to molten or hot liquid material (such as wax or metal) when it cools and hardens.

Question 13

cast

Answer 13

cause (light or shadow) to appear on a surface.

Question 14

unconformity

Answer 14

a surface of contact between two groups of unconformable strata.

Question 15

Mass Extinction

Answer 15

An extinction event is a widespread and rapid decrease in the biodiversity on Earth. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms

Question 16

Proterozoic

Answer 16

The Proterozoic is a geological eon spanning the time interval from 2500 to 538.8 million years ago.

Question 17

Silurian

Answer 17

The Silurian is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago

Question 18

Devonian Period

Answer 18

The Devonian is a geologic period and system of the Paleozoic, spanning 60.3 million years from the end of the Silurian, 419.2 million years ago

Question 19

Quaternary Period

Answer 19

The Quaternary Period is the third and last of the three periods of the Cenozoic Era.

Question 20

Permain Period

Answer 20

The Permian is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago, to the beginning of the Triassic Period 251.9 Mya.
