It is Earths' "Magnetosphere".
Earth's precession
why do you think scientists study earths interior?if you were a scientists ,will you undertake a study of the earths interior?
The earths crust is a part of the outermost layer.
you can fit 833 earths in saturn.
Mercury's mass = 0.055 x Earths, Volume = 0.056 x Earths Mars' mass = 0.1075 x Earths, Volume = 0.151 x Earths Venus' mass = 0.815 x Earths, Volume = 0.857 x Earths (Earth) mass = 1 x Earths, Volume = 1 x Earths Uranus' mass = 14.536 x Earths, Volume = 63.086 x Earths Neptune's mass = 17.147 x Earths, Volume = 57.74 x Earths Saturn's mass = 95.152 x Earths, Volume = 763.59 x Earths Jupiter's mass = 317.8 x Earths, Volume = 1321.3 x Earths
earths tempertures
I'm not 100% sure, but I believe it's because a star is made of Plasma. Which is a partially ionized gas. The Plasma forms together through Nuclear Fusion and creates a giant luminous ball called a Star. A Gas Giant is a planet not entirely composed of rock or other solid matter. The outlayer of a Gas Giant is what we see from space, and it is composed of gas. Jupiter and Saturn's outlayer is composed of primarily Hydrogen and Helium. The closer you get to a Gas Giant's core, the more the gas starts to compress and turn into liquid and than a solid.
earths matter is gas
the earths moon helps sustsian the gravity on the earths oceancs keeping them in balance
70% or 80% of water covers the earths surface
