Why Are Planets Round?

Our Solar System.

Big, small but round.

But, why all the planets and stars are round?

The eight planets in our solar system differ in many ways. They are of different sizes. They are different distances from the sun. Some are small and rocky, and others are large and gaseous. But all are nice and round. Why is that? Why don't they have cubes, pyramids or discs?

Planets are round because of a process known as "spherical shape formation". This process is caused by the forces of gravity and centrifugal force.

Gravity is the force that pulls all objects towards the center of mass. The stronger the gravity, the more compact an object will be. As a planet forms, the gravity of all the matter within it causes it to pull together and become denser. This results in the planet becoming more and more spherical in shape.

Additionally, as a planet spins on its axis, the centrifugal force caused by this rotation also contributes to the spherical shape. Centrifugal force is the force that pushes objects away from the center of rotation. As a planet spins, the centrifugal force pushes the matter at the equator outwards, making it less dense and causing it to bulge. This bulging effect, combined with the force of gravity, results in the planet having a spherical shape.

In summary, the force of gravity and centrifugal force work together to shape planets into the spherical shape we see today. The gravity of all the matter within a planet causes it to pull together and become more compact while the centrifugal force caused by its rotation results in the bulging at the equator and make it more spherical.

The average temperature of the planets

Within the Solar System, the average temperature on: • Pluto is around -235°C, • Neptune around -220°C, • Uranus -210°C, • Saturn -184°C, • Jupiter -153°C. • The temperature on Mars varies between about -87°C and -5°C, with an average of around -46°C. • The lowest natural temperature on Earth (recorded at Vostok, Antarctica in 1983) is -89°C; the highest surface temperature on Earth (recorded at Al 'Aziziyah, Libya in 1922) is 58°C; the mean overall temperature on Earth is 14°C. Planet Biography. Planets Surface Temperatures. Why temperatures differs from planets to planets? In general, the surface temperature decreases as the distance from the sun increases. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface above the lead's melting point of 880 ° F (471 ° C).

The Difference Between Being Intelligent And Being Wise

Intelligent : • wise, cunning, capable of thinking and reason Wisdom: • The state of being wise • Ability to use knowledge and / or experience wisely • Able to determine what is wise against what is unwise • A saying, a philosophy or other advice considered wise In Short: An intelligent man has a whole sea of knowledge and knows every fact. On the other hand, a wise man does not have all the knowledge that an intelligent man has, but he has the brain to know when to use knowledge. I have seen a lot of smart people make really stupid decisions. I was one of those people! The information I had before and after these decisions has not changed. But with every wrong decision, if I was willing to learn, my level of wisdom changed. The main difference is that: A smart or intelligent person knows how to solve any problem. A wise person knows how to avoid this problem. Knowledge makes a person intelligent. Experience makes a person wise.

Silt

Silt is granular material of a size somewhere between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil or as sediment mixed in suspension with water (also known as a suspended load) in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body. Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet. Silt can be visually observed with a hand lens. Sources:- Silt is created by a variety of physical processes capable of splitting the generally sand-sized quartz crystals of primary rocks by exploiting deficiencies in their lattice. These involve chemical weathering of rock and regolith, and a number of physical weathering processes such as frost shattering and haloclasty. The main process is abrasion through transport, including fluvial comminution, aeolian attrition and glacial grinding. It is in semi-arid envir
