2. Earth is round but did you ever wonder why it looks flat?

Earth is round but why looks flat

Talking about one of the effects of mass, it is that it attracts other mass. For small objects, like your computer, car, and even a building, the force of gravity is very small. But when you have millions, and trillions tons of mass, the effect of the gravity really increases. All of the mass pulls on all the other mass. This mass tries to create the most efficient shape that is a sphere.

For smaller objects, take the example of an asteroids, the force of gravity trying to pull the object into a sphere isn’t enough. This is very less to overcome the strength of the rock. Thus it keeps it in shape. Suppose you get above a certain mass and size, then the strength of the object can’t stop the force of gravity from pulling it into a sphere.

If the objects are larger than about 1,000 km in size, they are able to pull themselves into a sphere.

Goosebumps are physiological phenomenon which are inherited from our animal ancestors. This was useful to them. Goosebumps are tiny elevations of the skin. They resemble the skin of poultry after the feathers have been plucked. These bumps are caused by a contraction of miniature muscles.

These muscles are attached to each hair. Each contracting muscle creates a shallow depression on the skin surface. This causes the surrounding area to protrude. The contraction also causes the hair to stand up.

This happens whenever the body feels cold. In animals with a thick hair coat this rising of hair expands the layer of air. This serves as insulation. The thicker the hair layer, the more heat is remained.
