<h2>
Question no 4 answer</h2>
Fossil fuels will still provide 60% of energy in 2040, compared to 85% today, but the pattern of use will change, away from coal and towards gas, and increasingly concentrated in industry. Fossil fuel prices would be lower in a 2˚C scenario, with less need to mobilise high-cost reserves to meet demands.

The correct answer is D. Salt water.
Explanation
The hydrosphere is the system that groups all the waters of the earth that include oceans, seas, rivers, lakes, lagoons, frozen waters like ice and snow, among others. The water of the earth can be classified between salt water and freshwater, within the first group we find the oceans and the seas that represent two thirds of the total water of the earth, that is, 93 percent of the total water of the earth, a figure close to 1 370 323 000km³; the rest of the water is fresh and consists of rivers, lakes, lagoons, streams, groundwater, and glaciers. So, the correct answer is D. Salt water
