Very little is known about it due to a lack of research. Mercury, the Moon, Ceres, Europa, and Ganymede have surface boundary exospheres, which are exospheres without a denser atmosphere underneath. The Earth's exosphere is mostly hydrogen and helium, with some heavier atoms and molecules near the base. [2]
The world's biggest iceberg — a wall of ice the size of Rhode Island — is lumbering toward a remote island off Antarctica that's home to millions of penguins and seals. The trillion-ton slab of ice — called a megaberg — could slam into South Georgia Island and get stuck or be guided around it by currents.

Oberon – about 20% of Oberon's surface ice is composed of methane-related carbon/nitrogen compounds; Titania – about 20% of Titania's surface ice is composed of methane-related organic compounds [citation needed] Umbriel – methane is a constituent of Umbriel's surface ice; Neptune – the atmosphere contains 1.5 ± 0.5% methane [146]
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
In glaciology, an ice sheet, also known as a continental glacier, [24] is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 km 2 (19,000 sq mi). [25] The only current ice sheets are the Antarctic ice sheet and the Greenland ice sheet. Ice sheets are bigger than ice shelves or alpine glaciers.
