Increasing temperatures in the atmosphere have caused the temperature of the oceans to _______, leading to more powerful tropica
Serjik [45]

Answer No 1)

Increasing temperatures in the atmosphere have caused the temperature of the oceans to increase leading to more powerful tropical storms.

Approximately 25 percent of carbon dioxide emitted into the atmosphere is absorbed in the oceans.

Waste water treatment is critical to removing pollutants from contaminated water by using physical, chemical, or biological processes.

Water pollution can come from the decomposition of dead organic matter or animal waste in waterways.

Water pollution increases the salinity and slows down major ocean <u><em>currents</em></u> that are responsible for regulating Earth's climate.

Explanation:

The devastating effects of global warming effects both the land and the aquatic biomes.

The excess carbon dioxide produced as a result of global warming is absorbed by the oceans. This imposes a serious threat on the biodiversity of the aquatic life.  The dead organism also produce pollution when they degrade in the oceans.

It is essential that before ocean water is used for any kind of consumption, the water be effectively treated to remove all kinds of toxicity from it.

Answer 2)

Water quality can be improved through conservation by :

a) using less amount of water for house-hold purposes: In our daily lives, humans use extra amounts of water fro house- hold activities such as while washing clothes or washing dishes. It should be ensured that we use a reasonable amount of water for every house-hold activity.

b) Fix the leakages: Majority of the houses in a society will not be concerned about a minor water leakage from taps, pipes etc. But it is essential to conserve every drop of water and these leakages need to be fixed. The more water we conserve, the more improved quality water will be available.
