Question

1. Define the following:
1. Biosphere
2. Ecological imbalance
3. Global warming
4. Greenhouse effect
5. Ozone depletion
6. Acid rain​

Answer 1

Answer:

1.the part of the earth’s surface and atmosphere in which plants and animals can live.

2.Ecological imbalance is when a natural- or human-caused disturbance disrupts the natural balance of an ecosystem. The balance of an ecosystem can be disrupted by natural or human-caused disturbances. If a species disappears or a new species is introduced it can shift an ecosystem to a state of ecological imbalance.

3.Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

4.The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

5.Ozone depletion, gradual thinning of Earth's ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.

6.Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
