Age of the Earth
The age of the Earth is 4.54 ± 0.05 billion years This age may represent the age of the Earth’s accretion, of core formation, or of the material from which the Earth formed.

Algal bloom
An algal bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems, and is recognized by the discoloration in the water from their pigments.

Clastic rock
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock.

Climate change
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years).

Fern
A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers.

Fossil
A fossil (from Classical Latin fossilis; literally, "obtained by digging") is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Gamma ray logging
Gamma ray logging is a method of measuring naturally occurring gamma radiation to characterize the rock or sediment in a borehole or drill hole.

Geomagnetic reversal
A geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged, while geographic north and geographic south remain the same.

Greenhouse and icehouse Earth
Throughout the Phanerozoic history of the Earth, the planet's climate has been fluctuating between two dominant climate states: the greenhouse Earth and the icehouse Earth.

Homo
Homo (Latin homō "human being") is the genus that encompasses the extant species Homo sapiens (modern humans), plus several extinct species classified as either ancestral to or closely related to modern humans (depending on a species), most notably Homo erectus and Homo neanderthalensis.
