Answer:

The term “whale” is a word used to describe several different types of marine mammals, which include whales, dolphins and porpoises.

Together these three distinct animal groups make up what is known as the cetacean species.

While the name whale can sometimes refer to all cetaceans (whales, dolphins & porpoises) it usually excludes dolphins and porpoises in order to ensure that the three animal groups are easily identifiable.

nika2105 [10]

Answer: EVAPORATION.

Explanation: Salinity can be defined as the saltiness or the concentration of salt dissolved in a body of water. Measured in grams of salt divided by the kg of water.

Evaporation increases the salinity of water. Basically, evaporation is the process of converting liquid into gaseous state. In essence, concentration of a solution can be increased by evaporation and since the salinity of water is measured in grams of salt divided by the kg of water, therefore, the lesser the amount of water per salt, the higher the salinity.

Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas (LFG) over time. Abou
Stels [109]

The amount of LFG produced in a year from the calculations is 1.5768 * 10^8 cubic feet.

<h3>What is LFG? </h3>

The acronym LFG stands for land fill gas. It is a gas that is produced by the decomposition of biomass in a land fill. This gas can be burnt to generate steam. This steam is used to turn a turbine and generate electricity.

If 1 million tons of LFG is burnt in  a day, then 365 million tons of LFG is burnt in one year.

1 million tons of waste produces  432,000 cubic feet of LFG

365 million tons of waste produces 365 million tons * 432,000 cubic feet /1 million tons

= 1.5768 * 10^8 cubic feet of LFG
