Dirty Snowball
On land a large body of permanent ice is a glacier; in the water this is an iceberg.
The tundra biome has no large trees because much of the soil is frozen, making it difficult for trees to establish deep root systems. The cold temperatures and short growing season also limit tree growth in this biome.
Permafrost is considered a carbon sink because it stores large amounts of carbon in the form of organic matter that has accumulated and been preserved in frozen soil over thousands of years. When permafrost thaws due to rising temperatures, this organic matter is decomposed by microbes, releasing carbon dioxide and methane into the atmosphere, contributing to global warming.
Large amounts of coal can be found on the Central Siberian Plateau. The climate there is Tundra and Subarctic, which makes coal very hard to mine, because it's very cold and hard for the ground to stay frozen.

A comet .
A comet is a large body of frozen ice and rock that travels towards the center of the solar system. It orbits the sun in an elongated path, and as it gets closer to the sun, the heat causes the ice and rock to vaporize, creating a glowing tail that points away from the sun.
A comet be able to be of sun size.

A frozen large what?...
in the ark it is a large wooden structure that is considered holy
astroid
A large comet or asteroid striking earth
No. A Comet is a relative large body that is seen for many days. A meteor is the flash of a tiny bit of sand or gravel, usually left over from a comet.
a large lump of rock that is heading for a planet
What are comets made of? Gravity holds stars and planets together, but what holds the other (little stuff) together. Ionic bonds. And it turns out that are only 3 that seem to work: Water (ice), Silicon oxide rock, and ferromagnetic metals (iron, nickel, cobalt). Comets don't seem to have much metal, so "dirty snow-ball". In 1949, Fred Lawrence Whipple theorized that the nucleus of a comet is made of frozen water, rocky debris, and frozen gases. This was called the "icy comglomerate" theory and is now known as the "dirty snowball" theory. However, in 1999, the Stardust spacecraft was launched and in 2004 it retrieved tiny particles from the comet Wild-2's surface and came back two years later in a capsule, landing in Utah. Minerals that formed in the presence of liquid water were discovered, proving that, at some point, pockets of water had existed on the comet. This disproved the "dirty snowball" theory.
