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.
Which are the key factors in lake snow affect?
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.

It is estimated that global energy consumption will increase 28% between 2015 and 2040, with fossil fuels still providing the bulk of the energy consumption (77%) by 2040, according to a new report by the U.S. Department of Energy's Energy Information Administration (EIA). What are are two major issues with our reliance on nonrenewable energy sources? * A) environmental pollution and dwindling supplies B) electricity consumption and dwindling supplies () geographic location and abundance of supplies D) electricity consumption and geographic location
The two major issues with our reliance on nonrenewable energy sources are environmental pollution and dwindling supplies.
What are are two major issues with our reliance on nonrenewable energy sources?
Environmental pollution and dwindling supplies are two major issues with our reliance on nonrenewable energy sources because burning of fossil fuels release carbondioxide which is a pollutant. This fuel is present in limited countries but its consumption is very high. Sometimes they can't match the demand.
So we can conclude that the two major issues with our reliance on nonrenewable energy sources are environmental pollution and dwindling supplies.

Answer:
Oxygen helps organisms grow, reproduce, and turn food into energy.
Explanation:
Humans get the oxygen they need by breathing it in through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
Oxygen plays a critical role in photosynthesis for all plants.
Since flatworms have no lungs all their cells must be close to the skin to receive oxygen from the surrounding water or fluids.
Answer:
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and flip meals into energy. Humans get the oxygen they want by way of respiratory thru their nose and mouth into their lungs. Oxygen offers our cells the capacity to smash down food in order to get the power we need to survive
