1. In the U. S. Northeast, some lakes that were once considered good fishing spots no longer have fish living in them. The reason fish cannot survive in these lakes is because

a. of the greenhouse effect.

b. of global warming.

c. the burning of fossil fuels has created acid rain.

d. of the depletion of the ozone layer.

2. The burning of fossil fuels allows sunlight to enter Earth's atmosphere freely but inhibits the release of heat. This is referred to as

a. global warming.

b. the depletion of the ozone layer.

c. the greenhouse effect.

d. acid rain.

Answer 1 : (C) the burning of fossil fuels has created acid rain.

Answer 2 : (C) Greenhouse effect.

c. the burning of fossil fuels has created acid rain.

c. the greenhouse effect.

Explanation:

Acid rain is a form of rain that contains an unusually high level of hydrogen ions (low pH). Acid rain is caused by the presence of sulfur dioxide and nitrogen oxide in the atmosphere. This is a consequence of pollution. Acid rain has a strong negative effect in forest, freshwaters, soils, insects, aquatic life-forms, paint, steel structures, stone buildings, statues and human health. The greenhouse effect is a process by which the Earth's atmosphere warms the planet. While the Earth has a natural greenhouse process that allows life to exist, greenhouse gases that are in the atmosphere due to pollution make this effect stronger. Greenhouse gases radiate energy in all directions, including towards the surface of the Earth, heating it. Moreover, they do not allow the heat to escape.
