Although not a supercontinent, the current Afro-Eurasia landmass contains about 57% of Earth's land area.

Rodinia (from the Russian родина, rodina, meaning "motherland, birthplace" ) was a Neoproterozoic supercontinent that assembled 1.1–0.9 billion years ago and broke up 750–633 million years ago.

The rock cycle shows the relationship between igneous, sedimentary, and metamorphic rocks.

The major events of this era are the breakup of the Columbia supercontinent, the formation of the Rodinia supercontinent, and the evolution of sexual reproduction.

It is generally believed that small proto-continents existed before 4280 Ma, and that most of the Earth's landmasses collected into a single supercontinent around 1130 Ma. The supercontinent, known as Rodinia, broke up around 750 Ma. A number of glacial periods have been identified going as far back as the Huronian epoch, roughly 2400–2100 Ma. One of the best studied is the Sturtian-Varangian glaciation, around 850–635 Ma, which may have brought glacial conditions all the way to the equator, resulting in a "Snowball Earth".

Columbia (supercontinent)

The supercontinent Columbia about 1.6 billion years ago

Columbia, also known as Nuna or Hudsonland, was one of Earth's ancient supercontinents.

Siberia (continent)

Current location in Asia

Around 1.1 billion years ago (Stenian), Siberia became part of the supercontinent of Rodinia, a state of affairs which lasted until the Cryogenian about 750 million years ago when it broke up, and Siberia became part of the landmass of Protolaurasia.

Although Afro-Eurasia is typically considered to comprise two or three separate continents, it is not a proper supercontinent.

Gondwana was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic (about 180 million years ago).
