What is a human-environment interaction in Pittsburgh?
Paving a parking lot with asphalt means that rain and snow cannot sink into the ground. The water will run directly to the river, causing a rapid rise in water levels.
Will inland rivers such as those in northern Mississippi flood if sea levels rise?
No, rivers will flood at low-lying area near their mouths, where the sea levels will rise. The height of river water depends on the rainfall received into the watershed. If sea level rises, that will have no effect on flow rate upstream.
What causes water to rise?
the melting of ice or glaciers
Why do river levels be at their highest a few days after heavy rain?
There is a delay as the rain soaks into the ground or runs off the watershed down to a river or stream. This delay means that hours or days after heavy rain river levels rise. After a long drought the ground may be so hard the water runs straight into the river system, hence flash flood after droughts.
What happens when ship rise enters the sea from a river?
A sea has salty water so therefore it has a higher density than river water. The sea basically is "thicker water" so the ship will rise.
Which is a reason for the rise of nitrate levels in ground water?
overuse of fertilizers
Which river water of US rise every year?
Mississippi.
What happens when a ship enters the sea from a river?
