Alpine tundra is generally similar to arctic tundra. However, alpine tundra has a longer growing season. Alpine tundra is found at high altitudes above the tree line throughout the world. The closer to the equator, the higher the altitude required. Even on the equator, there are still mountains high enough to have some areas of alpine tundra. Alpine tundra soils are generally well drained, but rocky subsoils serve the same function as arctic permafrost. Alpine tundra has a unique community of organisms different from arctic tundra.
In large lakes the deep water will never freeze, remaining about 4°C (39° F). Since the hydrogens sort of cluster on one side, and oxygen is more electronegative than hydrogen. The slightly positive end of o; water molecule will “bond” with the slightly negative end of another water molecule. Like magnets.
This occurs to some extent naturally, because it takes less energy to just let two magnets stick together than it does to hold them a centimeter apart, right? So when the temperature outside drops, more hydrogen bonds are formed, which conserves the energy of the molecules, allowing them to remain in liquid phase, (this is, in fact, the same reason water crystallizes in such a weird way when it’s freezing, making it LESS dense as a solid.)
Likewise, it takes water longer than most other things of comparable molecular mass because, as heat is added, hydrogen bonds break and molecules take on energy instead of buzzing around and evaporating.
