Water found on Earth's surface is very important to the world and the people everywhere. We need water to survive but it becomes more of a want considering that so many people don't have as much water supply as some of us do and we take it for granted. We also need it for crops and farming. Water has to be one of the most important substances to survive and it is all around us.
Did you know that earth is known as the blue planet? and that it appears blue from space from the oceans reflection? 70% of earth is covered in water and that leaves 30% to be dry land. But if we were to drain all the water out then we would see that the 7 continents cover 40% of the earth and 60% is ocean basins. This is because when we say 70% of the Earth is water we are referring to oceans, lakes, rivers ponds, ect. But 10% of that water is not ocean. So if we were to drain out all the lakes and rivers it would become dry land; so that percentage rises as the water decrees.
Out of all the four oceans; Pacific, Atlantic, Indian and arctic, the Pacific Ocean is by far the largest and deepest of them all. It is approximately 35, 797 ft deep which is deeper that the highest mountain Mount Everest which is 29,035 ft high. It spreads from Bering Sea in the north arctic to Antarctica's Ross Sea in the south. And it covers about a third of the earth's surface.
The smallest ocean is the arctic ocean which is 10 times smaller than the Pacific Ocean. Egypt is the home of the world’s longest river “The Nile River”. It is 4,145 miles or 6,671 km long and goes into the Mediterranean Sea. The ancient Egyptians lived along the river to farm and provide food for their people and animals. Papyrus also grew along the river and it was a good way to trade products because it was a quick and easy way to travel.
