1)D) Fission is the process when the nucleus of an atom splits after being bombarded by neutrinos.

2)A) Storage and disposal of radioactive waste is a problem all nuclear power plants face. Most of them dipose the waste underneath the ground. There have even been proposals to send the nuclear waste to the moon.

3)C) Nuclear Power because it does not produce greenhouse gas emissions.

4)A) Oil is more difficult to remove from the Earth than coal This is why, to extract oil, you need an extraction pump and other equipment, while coal can be removed from the earth after digging.

5)A) biofuel - because it comes from agriculture, and agriculture is the biggest contributor to worldwide greenhouse emissions.

6)B) Geothermal power - geothermal power uses the heat from the earth to produce energy.

7)D) - Humans have seemingly unlimited needs and these needs have to be met without destroying the enviroment.

8)C) Xenon - The other three substances listed are classified as Ozone depleting susbstances according to the Ministry of the Enviroment in New Zealand.

9)B) Synthetic materials often do not decay naturally - The best example is plastic, which is a synthetic material that takes hundreds or even thousands of years to decay.

10)C) An environmentally safe base to neutralize the lake - This can be done by oxygenizing the lake.

11)D) Oil spills - Unfortunely, these events have taken place many times. The oil spill in the Gulf of Mexico caused by British Petroleum greatly affected the coasts and waters of Louisiana.

12)D) The whole ecosystem is negatively affected, and long-term damage may occur - An oil spills afects aquatic plants, animals, birds, and the water itself.

13)B) Natural resources will be depleted - Oil might even run out completely. Besides, climate change would raise the sea levels and flood thousands of cities.

14)D) factories and power plants - especially thermal power plants that burn coal to produce energies.

A spring is a natural discharge point of subterranean water at the surface of the ground or directly into the bed of a stream, lake, or sea. Water that emerges at the surface without a perceptible current is called a seep. Wells are holes excavated to bring water and other underground fluids to the surface.

Answer with explaination:

 An attempt to document and identify all biological species living in some defined area, usually a park, reserve, or research area. The numbers of species on earth is rapidly diminishing, knowing what species are around will give us an idea of what we're losing, how our actions are affecting the environment.
