Answer:

Rain is possible only due to oceans. The continents will become desert. More than half of the world’s oxygen is produced by the ocean’s flora, which is why they are called ‘the planet’s lungs’. The oceans, therefore, play a crucial role in regulating the climate and sustaining life on the Earth. Oceans also provide transportation and major sources of medicines, food to human beings.
