How does the greenhouse effect influence the climate on earth? choose the best possible answer.
Arturiano [62]

The greenhouse effect influences climate by increasing the global temperature.

<h3>What is greenhouse effect?</h3>

The greenhouse effects are effects due to the presence of greenhouse gases in the atmosphere.

The greenhouse gases form a layer of gas in the atmosphere and prevent reflected solar radiation from escaping back into space. They, therefore, warm up the atmosphere by increasing the thermal energy.

As the concentration of the greenhouse gases in the atmosphere increases, so also is the amount of reflected solar radiation that is trapped in the atmosphere.

Therefore, an increase in greenhouse gas concentration increases the global temperature. Temperature influences other climatic factors such as precipitation.

Thus, the greenhouse effects influence climate by causing a rise in global temperature.
