Identify the events that lead to a lake-effect snow.
Pavel [41]

Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more.

<h3>Which are the key factors in lake snow affect?</h3>

Wind direction is a key component in determining which areas will receive lake effect snow. Heavy snow may be falling in one location, while the sun may be shining just a mile or two away in either direction.

The physical geography of the land and water is also important.

wind energy gaining support as a possible energy source for people. what is the source of the energy that generated wind?
Ivahew [28]

<u>Answer</u>: The energy source that generates wind is actually the sun.

<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.
