Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust.

​​The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly com​posed of basalt.

Complete answer: The Earth is divided into three major layers- Crust (outermost), mantle and core (innermost). Three main layers are classified into the Earth-Crust (outermost), mantle and core (innermost).

Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.

PROVIDENCE, R.I. — Scientists say they have discovered the thinnest portion of the Earth’s crust — a 1-mile thick, earthquake-prone spot under theAtlantic Ocean where the American and African continents connect.

The central point of the Earth is over 6,000km down, and even the outermost part of the core is nearly 3,000 km below our feet. The deepest hole we’ve ever created on the surface is the Kola Superdeep Borehole in Russia, and it only goes down a pitiful 12.3 km.

Explanation: Lithosphere is all the solid part of the Earth’s surface. So, the crust and oceanic crust are included up to the upper mantle. The oceanic crust’s depth is up to 8 km , up to the upper part of the mantle, the lithosphere is at its thinnest.

In general, the scientific community accepts that the yolk of an egg is one single, massive cell, thousands of times bigger than typical cells.

The Earth is an irregularly shaped ellipsoid. While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.

Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.

Almost two times the size of our Jupiter, WASP-12b is a sizzling gas giant whose temperature is approximately 4,000 degrees Fahrenheit (2,210 degrees Celsius). Gravity causes enormous tidal forces which are stretching the planet into the shape of an egg.

From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. The equator is a make-believe line around the center of Earth.

A planet is round because of gravity. A planet’s gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.

The exoplanet was identified by the Kepler space telescope, and its discovery was announced by NASA on 23 July 2015. The planet is about 1,800 light-years away from the Solar System….Kepler-452b.

The Sun and all eight planets of the solar system are round. Why? The gravitational force of a planet’s mass pulls all of its material toward the center, smoothing out any jarring non-roundness. Many of the smaller bodies of the solar system are not round because their gravity is not enough to smooth out their shape.

Smaller asteroids are generally not round. This is because small asteroids have very weak gravitational pulls, meaning they cannot pull all the material surrounding them towards their center equally. Therefore, unlike planets, these small asteroids are not spherical and round.

Planets are round because their gravitational field acts as though it originates from the center of the body and pulls everything toward it. The only way to get all the mass as close to planet’s center of gravity as possible is to form a sphere.

While Earth’s axis is tilted about 23 degrees, Uranus tilts almost 98 degrees! Uranus’ axis is so tilted, it actually looks like the planet is rotating on its side.

In 2011, simulations showed that it was more likely that a series of smaller collisions, rather than a large impact, tilted Uranus’ spin angle to 98 degrees. The alternative hypothesis was that Uranus had a very large satellite that caused the tilt of its orbit, and at one point was hit by another planet.

Uranus

The ice giant is surrounded by 13 faint rings and 27 small moons as it rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus appear to spin on its side, orbiting the Sun like a rolling ball.
