I feel privileged to be a part of this context which consists of an endless treasure of general knowledge. I am trying to answer the questions of today's episode of general knowledge. Let's start the main discussion.

About 71% of the earth's surface is water. Again 97.5% of this total water is located in the oceans. There are 5 oceans on earth. These 5 oceans contain 97.5% of the water. The oceans are:-

• Pacific Ocean: -The world's largest and deepest ocean is the Pacific Ocean. It is spread over Asia, Australia, America and Antarctica.
• Atlantic Ocean: -The Atlantic Ocean is the second-largest ocean in the world. It is spread between America, Europe, and Africa.
• Indian Ocean: -The Indian Ocean is called the third largest ocean. It is spread between Africa, Asia, and Australia.
• Southern Ocean: - It is the fourth largest ocean in the world. It is also called as Antarctic Ocean. It surrounds Antarctica.

Gravity is a fundamental force in nature that attracts objects with mass to each other. The theory of gravity was developed by the famous scientist Sir Isaac Newton. In 1687, Sir Isaac Newton published his Philosophiae Naturalis Principia Mathematics, which became known as the Principia. In that book, Newton formulated his law of universal gravitation and proposed that every mass in the universe is proportional to the product of their masses and attracts each other. This law revolutionized the understanding of gravitation and laid the foundation for classical mechanics.

In the human body, bone is a body component that forms the body structure. It protects the vital organs of the body and facilitates movement. The human body is made of lot of bones. The number of bones in a newborn and an adult person varies slightly.
A newborn has 270 bones and an adult has 206 bones. Although apparently, the number of bones in newborns and adults is different, the number of bones is actually 270. As the age increases, some bones merge together. As a result, the number of bones decreases to 206.
Let me give you an example - As the baby grows, some bones in the skull fuse together so that the bones cannot be identified separately.
Thus 270 bones are converted into 206 bones.
