What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

The continents we live on today are moving, and over hundreds of millions of years they get pulled apart and smashed together again. Occasionally, this tectonic plate-fueled process brings most of the world's landmasses together to form a massive supercontinent.

There's no strict definition for a supercontinent, but researchers like Joseph Meert, a professor of geosciences at the University of Florida, say they should include around 75% of the available landmass.

Scientists are still debating how many supercontinents have existed in Earth's history, but they're sure of at least three. Here are all of the known supercontinents that have existed and a few honorable mentions. Live Science spoke with Meert, to check the dates of the supercontinents on this list, but keep in mind they're still only estimates.

Re: @ZLabe@fediscience.org

It was an unbelievable year for global climate.

As data is released in the first two weeks of January, you are going to be hearing all about these new climate change records. Apologies for all my graphs in advance!! 😬
