Q. Is Earth getting fatter?

The Earth is not getting bigger. Deposition (of sediments, mostly marine) and weathering (erosion) are in approximate equilibrium. Most weathering occurs on land while most deposition occurs in the seas, resulting in a net accumulation of marine sediment.

Q. Do you weigh more on the equator?

Yes, you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles.

Q. How Is the Earth getting bigger?

Earth isn’t getting bigger. It’s actually getting smaller! Space around Earth is dusty; it’s full of asteroid debris, comet trails and ionized particles streaming away from the sun. And as our planet flies through that dust, our gravity vacuums it up.

Q. Why is the earth not getting bigger despite the fact that?

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth’s surface. But the Earth isn’t getting any bigger. Deep below the Earth’s surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.

Q. Who invented super Earth?

The first super-Earths were discovered by Aleksander Wolszczan and Dale Frail around the pulsar PSR B1257+12 in 1992. The two outer planets (Poltergeist and Phobetor) of the system have masses approximately four times Earth—too small to be gas giants.

Q. What is the biggest super Earth?

Kepler-145b is one of the most massive planets classified as mega-Earths, with a mass of 37.1 M ⊕ and a radius of 2.65 R ⊕, so large that it could belong to a sub-category of mega-Earths known as supermassive terrestrial planets (SMTP).

Q. How did we find Earth?

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

Q. How does NASA pronounce Uranus?

According to NASA, most scientists say YOOR-un-us.

Q. What is Uranus nickname?

Uranus is known as the “sideways planet” because it rotates on its side. Uranus was discovered in 1781 by William Herschel.

Q. Can you breathe on Uranus?

The planet Uranus indeed contains a significant amount of hydrogen and methane, both highly flammable gases. Simply put, there is no free oxygen on the planet Uranus.

Q. Can you survive on Mars without a spacesuit?

The atmospheric pressure on Mars varies with elevation and seasons, but there is not enough pressure to sustain life without a pressure suit.
