Do you think the description of a blue planet is accurate? Describe any one way your activity impacts its oceans.

Answer :

The description of the blue planet is accurate for the earth. It is said to be a blue planet because most of the surface is covered with water and hence it makes a blue colour. 71% of the earth's surface is covered with water and only 29% is land. Earth is the fifth largest planet in the solar system and third when compared to the distance from Sun. Earth is the unique planet which supports life for human sustenance. Water is the main reason for the availability of life on earth.

The ocean is the main water body which makes the planet earth blue. There are many human activities which have an adverse effect on the oceans, water bodies and ice glaciers. One such activity which has the most impact on the ocean is global warming. Global warming increases in the earth's temperature due to an increase in human activities. It occurs due to the climate changes that happen in the earth.

The average earth's temperature is increased due to global warming by the greenhouse gases. The greenhouse effect is the absorption and emission of infrared radiation and CFCs gases that are emitted by human beings on the planet. The atmosphere gets polluted and these gases get trapped in the ozone layer which will increase the temperature of the earth by depleting the ozone layer. The ozone layer is the layer which protects the earth from the harmful rays of the Sun. When the temperature of the earth raises the ice glaciers in the Arctic region and Antartic region starts melting and increases the sea level which is harmful to the earth.

In this way, human activity has an adverse impact on the oceans and earth.
