Ugo [173]

Answer: The diagrams above show an area that <u>was once a pasture</u> that has since undergone changes to the <u>vegetation </u>over time.

The following changes in the <u>hydrologic cycle</u> is most likely to occur as a result of the change in vegetation in the area:

  • Decreased precipitation.

Explanation:

When we <em>lose vegetation</em> in an area we face serious problems, one of them is the decreased precipitation . If changes are <em>made by man</em>, for example, as in deforestation, the consequences are <u>even worse.</u>

<u><em>Deforestation </em></u>can cause a serious <u>reduction of rainfall</u> in the tropics, with serious consequences for the population not only in that region but in <em>neighboring areas.</em> The air that passes over large areas of tropical forest produces at least twice as much rain as that which travels over areas of low vegetation .

In turn this also <u>affects the other factors</u> of the cycle. The vegetation <em>contributes</em> moisture through an <em>evapotranspiration process</em>, as it is called the evaporation of the rivers together with the transpiration of the plants. This moisture is transported by the winds.

We can say then that <u><em>the loss of vegetation</em></u> in an area (whether on purpose or not) <u><em>will corrupt several cycle factors</em></u>, mainly damaging the rainfall rate.

Based on current data;

  • The amount of carbon dioxide put into the atmosphere annually dueto human activities is 840 gigatons
  • The amount of carbon in the atmosphere is 10 gigatons
  • The amount of carbon stored in fossil fuels is 10,000 gigatons

<h3>What is the carbon cycle?</h3>

The carbon cycle a cycle showing how carbon is recycled between the atmosphere and earth.

The carbon cycle ensures that their is a balance of carbon in the atmosphere as well as on earth.

Human activities have increased the amount of carbon in the atmosphere.

The amount of carbon dioxide human activities put into the atmosphere annually in the present day is 840 gigatons.

The amount of carbon in the atmosphere is 10 gigatons

The amount of carbon stored in fossil fuels is 10,000 gigatons

Therefore, it can be concluded that human activities disrupt the carbon cycle.
