A black smoker, a type of hydrothermal vent. A tremendous glaciation would curtail photosynthetic life on Earth, thus depleting atmospheric oxygen, and thereby allowing non-oxidized iron-rich rocks to form. Detractors argue that this kind of glaciation would have made life extinct entirely.
Seinen. Original run. January 27, 2021 – present. Volumes. 7. Snowball Earth (Japanese: スノウボールアース, Hepburn: Sunoubōru Āsu) is a Japanese manga series written and illustrated by Yuhiro Tsujitsugu. It has been serialized in Shogakukan 's seinen manga magazine Monthly Big Comic Spirits since January 2021.
An illustration of ice age Earth at its glacial maximum. A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet. [6] Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (82.4 °F) in the tropics to 0 °C (32 °F) in the polar regions.

The Marinoan glaciation, sometimes also known as the Varanger glaciation,[2]was a period of worldwide glaciation.[3] Its beginning is poorly constrained, but occurred no earlier than 654.5 Ma(million years ago).[4] It ended approximately 632.3 ± 5.9 Ma[3]during the Cryogenianperiod.
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
The Bølling–Allerød Interstadial (Danish: [ˈpøle̝ŋ ˈæləˌʁœðˀ]), also called the Late Glacial Interstadial (LGI), was an interstadial period which occurred from 14,690 to c. 12,890 years Before Present, during the final stages of the Last Glacial Period. [2]
The cryosphere is an umbrella term for those portions of Earth 's surface where water is in solid form. This includes sea ice, ice on lakes or rivers, snow, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost). Thus, there is a overlap with the hydrosphere.
An ice planet or icy planet is a type of planet with an icy surface of volatiles such as water, ammonia, and methane. Ice planets consist of a global cryosphere. Under a geophysical definition of planet, the small icy worlds of the Solar System qualify as icy planets. These include most of the planetary-mass moons, such as Ganymede, Titan ...
