dmitriy555 [2]
Salt Lake City, Utah is located in a warm desert like area where there are little to no bodies of water for evaporation. New York City however, is located right on the east coast next to an ocean which allows for water to evaporate and fall over New York more than in Utah. This is also why New York gets more snow in the winter. This is known as the lake effect.

Describe the steps that were involved in the making of the sun​
Vesnalui [34]

Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form the sun.
