Earth's history and climate changes

I will get an A on this quiz

Geochronology

The scientific discipline focused on measuring and understanding the time aspects of Earth's history.

Relative dating

A technique used to establish the sequence of geological events or layers in relation to one another.

Numerical dating

A method employed to determine the actual age of geological events or formations expressed in years.

Geologic Time Scale

A framework that outlines the chronological order of significant events and periods in Earth's history.

Milankovitch cycles

Variations in Earth's orbital characteristics that influence climate over a range of thousands to millions of years.

Glacial periods

Extended intervals of low temperatures lasting around 100,000 years, marked by widespread ice cover.

Interglacial periods

Warmer phases occurring between glacial periods, typically lasting about 10,000 years.

Carbonate-silicate cycle

A geochemical process that regulates Earth's surface temperatures through the recycling of carbon dioxide and silicate minerals.

Coalification

The transformation of accumulated peat into coal due to geological stress and heat over time.

Ice cores

Cylindrical samples extracted from glaciers or ice sheets that provide invaluable climate data spanning hundreds of thousands of years.

Sources of greenhouse gases

Includes carbon dioxide from fossil fuel combustion, methane from thawing permafrost, and various gases emitted by volcanic activity.

Plate tectonics and climate impact

The study of how the movement of Earth's tectonic plates influences climate patterns and distribution over geological time.

Historical CO2 levels

The analysis of past atmospheric carbon dioxide concentrations and their correlation with global temperature changes, currently at 414 ppm.

Role of solar radiation

The significance of variations in incoming solar radiation affecting climate, including aspects like albedo and orbital mechanics.

Consequences of global warming

Results of climate change that encompass ice retreat, rises in sea levels, ocean acidification, and increased severity of storms.
