Lake effect snow is the result.
Lake effect snow is a heavy and localized snowfall that is traceable to the great lakes. During the winter season, this type of snow results when cold air moves over lake waters that are warm.
Given that the temperature of the lakes are more than that of the cold air that came in contact with the lake, it would cause moisture to go up.
This moisture and high temperature is what combines together for there to be snow.

Answers
Answer:
This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct.
The ones that will be discussed in this article are competition, predation, herbivory and symbiosis. These are not the only types of species interactions, just the most studied — and they are all parts of a larger network of interactions that make up the complex relationships occurring in nature.

A satellite is a body that orbits a planet, star, or moon. For instance, the fact that Earth orbits the sun makes it a satellite. The moon is a satellite as well because it revolves around Earth. The term "satellite" typically refers to a device that is launched into space and orbits the Earth or another celestial body.
