Contest alert! || Sharing my general knowledge week 3

I am eager to participate in the contest organized by @sahar78 on Steem for Pakistan. The contest theme is "Share your general knowledge." Let us start with addressing intriguing inquiries to demonstrate our expertise and enhance our collective learning experience.

How many oceans are in world?

The world has five seas around it. Earth's seas are all different from one another and have a big effect on the temperature, weather, and types of life that live in the world.

Pacific Ocean

🔹This ocean is both the deepest and biggest on Earth.
🔹It spans an area of more than 63 million square miles.
🔹Encompasses the Mariana Trench.
🔹 Surrounded by Asia, Australia, and the Americas.

Atlantic Ocean

🔹The ocean that ranks second in terms of size.
🔹About 41 million square miles in size.
🔹Between the regions of Europe, Africa, and the Americas.
🔹It has the Mid-Atlantic Ridge in it.

Indian Ocean

🔹The ocean that ranks third in terms of size.
🔹Covers an area of about 27 million square miles.
🔹The Southern Ocean and the countries of Asia, Africa, and Australia are all around it.

Southern Ocean

🔹Surrounds Antarctica.
🔹Encompasses around 7.8 million square miles.
🔹Crucial for the management of the Earth's climate on a global scale.

Arctic Ocean

🔹The ocean with the smallest surface area and the least average depth.
🔹Encompasses around 5.4 million square miles.
🔹Situated in the vicinity of the Arctic area.
🔹Defined by the presence of polar ice.

Which scientist developed theory of gravity?

The idea of gravity came from the scientist Sir Isaac Newton. Mathematical Principles of Natural Philosophy, or "The Principia," was his most famous book, which came out in 1687.. In this work, he came up with the ideas behind global gravity and the rules of motion. There is a force between all masses in the world that is equal to the product of their masses and opposite to the square of the distance between their centers. This force is called Newton's rule of universal gravity. This very important work, which led to classical physics, made us much smarter about the natural world.

How many total bones present in a newborn and adult?

As a baby, a person usually has about 270 bones. By the time a person is an adult, 206 bones have fused. This decrease in number mostly happens in the brain, spine, and hips, where bones slowly join together to form stronger structures. This change helps the body grow and develop by creating a stable structure for moving and keeping important parts safe. During the process of growth, certain bones eventually undergo fusion, leading to a reduction in the overall count of bones. This process persists throughout infancy and youth.
