an essay on What if the Oceans did not exist.
Answers
Answer:
Well, without the oceans, the world loses 97% of its water. The small amount of liquid left wouldn't be enough to sustain the water cycle. The pools of drinkable water would evaporate pretty fast. In a matter of days, people and most animals would die from dehydration.
Explanation:
The oceans of the Earth can exist without us. If we humans become extinct, they won’t even notice we’re gone. We, however, simply cannot exist without our oceans. We need them. They are the primary life support system on Earth, the lungs, climate regulator, and ultimate food factory - connected deeply to each of us and nearly every economic activity that makes our world go round.
For those old enough to remember - and for the young and curious, too - you may know “Earthrise,” the iconic photograph taken on 24 December, 1968 by a 35-year-old American astronaut and engineer named William Anders as he looked through a small, frosty window of Apollo 8, the first spacecraft to leave Earth’s gravity and orbit the moon.
From 380,000km away, our spectacular planet appeared as a vulnerable, mostly blue sphere, vividly illustrating their size and importance – they cover some 70% of the Earth with an average depth of four kilometers.
Since then, we’ve explored just 10% of our oceans’ contents. We’ve learnt they provide 99% of the Earth’s living space and contain around 80% of all living organisms. They are the largest space in our universe known to be inhabited by organisms.
They provide our Earth with a moist, livable climate, full of oxygen from trillions of microscopic plants floating like tiny stars in a watery, immense universe, producing close to 100 million tons of food each year, enough to provide one in every four or five people with their daily protein.
They are also crucial to our climate system. There is more heat stored in the first 10 feet of the ocean than in the entire atmosphere. This is significant because heat is transferred from the atmosphere to the ocean. Then currents move heat throughout the ocean and across the planet. The gulf stream, an intense warm current, is the major source of north-south heat transfer in the Atlantic. It starts in the Gulf of Mexico, snakes around Florida, and then goes northeast across the Atlantic, expanding like a funnel until it gets to Europe.
