Explanation / Answer

Ans

8) Primary environmental benefit of wetland areas is -

1.Carbon Sink- Because the soils found in wetlands can store carbon for hundreds of years, they play an important role in fighting climate change.

2 Pollution Filter- If trees are the lungs of the planet, then wetlands are its kidneys. On the Rouge River near Detroit, Michigan, a wetland demonstration project showed significant reductions in nitrates, phosphorus, and heavy metals. Clean and plentiful drinking water depends on healthy wetlands.

3.Sea Level Rise Mitigation, 4. Storm Buffer, 5. Wind Buffer, 6. Fertile Farm Land.

9) By this its genrated radiactive hazardious material so its nacesory to keep safe - Nuclear waste is neither particularly hazardous nor hard to manage relative to other toxic industrial waste. Safe methods for the final disposal of high-level radioactive waste are technically proven; the international consensus is that geological disposal is the best option.

10) Ozone protect from harmful ultravialet rays thats is causes of diseases and skin cancer.

11) Carbon monoxide (CO)—a colorless, odorless, tasteless, and toxic air pollutant that is produced in the incomplete combustion of carbon-containing fuels, such as gasoline,natural gas, oil, coal, and wood. The largest anthropogenic source of CO in the United States is vehicle emissions.

12) I think most common is industrialization, Since the dawn of human industry, the leading cause of extinctions has been loss of habitat and animals finding their homes destroyed to the point at which their survival is no longer possible. Habitat fragmentation will remain the sole cause of species extinction.

14) About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers etc.

15) Oxygen and water

Explanation - byproduct of photosynthesis is oxygen, on which most organisms depend. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms are veritable sugar factories, producing millions of new glucose molecules per second.

16) Troposphere

Explanation - The atmosphere has 4 layers: the troposphere is that we live in near the surface of the earth.he troposphere is where all of Earth's weather occurs. It contains approximately 80% of the total mass of the atmosphere.
