ocean. A typical ocean albedo is approximately 0.06
e, Both a and b. due to an upwelling of cold water from deeper levels in the east Pacific and in an El Niño year, the plankton is reduced and in turn the fish stocks, mostly through failure to reproduce.
e. all of the above. They are form when different temperatures and humidity meet. Generally, warm air rises, but when the two fronts meet, the cold air can trap the warm air beneath it. Because the warm air cannot move upward, it begins to rotate. As the sun heats the ground, more warm air continues to rise, until finally the mass is strong enough to push through the cold air barrier. The rising warm air pushes the cold air beneath it, creating a rotating column that can span up to 10 miles, while twisting at speeds exceeding 200 mph (322 km/h). Thus forming tornados.
