Is Solid waste point source pollution or non point source pollution?
Yanka [14]

Answer:

Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.

In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.

Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Destruction of tropical rain forests: helps maintain global temperatures
aliya0001 [1]

Answer:

B. reduces the amount of water vapor

Explanation:

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
