Isotopic dating is a method used to determine the age of geological materials by measuring the ratios of isotopes in the material. This process is significant because it provides scientists with a precise way to estimate the age of rocks, fossils, and other geological samples, helping to understand the Earth's history and evolution.
To summarize, there are three types of geological evidence of the age of the earth. These are:Gradual processes of rock formationThe fossil recordRadioactive dating
The age of a rock can be determined through radiometric dating techniques, comparing the ratios of certain elements in the rock to known decay rates. By analyzing the age of the rock in relation to the ages of other rocks in the surrounding area or in similar geological contexts, scientists can establish the relative age of the rock within the geological timescale.
The geological term for an ice age is a "glacial period" or "glaciation." These are times in Earth's history when ice sheets and glaciers advanced over large portions of the planet's surface, leading to colder temperatures and lower sea levels.
It means years x 10 to the power of 9. It is the unit that the age of of the earth is measured in. It stands for Giga Anum Giga = 10^9 and Anum = 1 year
The Mesonychid is a descendant of the whale. Some look like wolves, otters, and many modern predators.
The Mesonychid fossil was found in the early 19th century, specifically in the year 1821.
Glacial Age.
True. Numerical age is the age of a rock or geological feature in years, typically determined through radiometric dating methods.
The Precambrian is a geological age, not a mineral.
The geological or historical age refers to the time period during which certain events or processes occurred in Earth's history. It is determined based on the age of rocks, fossils, or other geological evidence found in a particular area. This information helps scientists understand the timeline of Earth's development and evolution.

A geological unit is an identifiable - "mappable" volume or layer of rock where the relative age can be determined. The link below gives more detail.

The most recent Ice Age
It is a French word meaning historically 'age or era'. In geological times a period, as in 'ice age' for example
