Question

Solar radiation travels through the earth's atmosphere and warms the planet's surface. Greenhouse gases like carbon dioxide in the earth's atmosphere reabsorb the heat and warm the planet. The amounts of greenhouse gases have been increasing over the past century, causing the earth's surface temperature to increase. This gradual temperature change is thought to have many negative environmental consequences.

Answer 1

It leads to global warming as more heat energy is absorbed by the excess greenhouse gases to warm the earth.

This may lead to melting of ice-poles with consequent rise in aquatic bodies.

Thus excessive rainfall may follow, with increased aquatic bodies volume leading to massive flooding.

Temperature fluctuations may also need to fluctuation in weather with excessive heat causing dehydration and evaporation causing drought.

As the concentration of CO2 increases in atmosphere, they are absorbed by the ocean bodies to be converted as H2CO3 acid,increasing the acidic levels of the ocean- hence oceanacidification.

Step-by-step explanation:

Answer 2

increase in the sea level and droughts

Step-by-step explanation:

The increase in the temperature of the atmosphere results in many catastrophic changes. These changes upset the life on the earth. For example, the increase in the temperature causes the surface if the polar ice to be warmer. As the ice becomes warmer, it melts and increases the level of the water in the sea. This causes islands to be covered. Thin addition, the coastal areas are also in danger of flooding. In addition, the increase in the temperature causes the droughts. These can be due to floods or desert conditions. Lastly, this causes fires, e.g. Australian fires.
