What is Mercury’s surface made of?
Scientists believe that Mercury has an interior composition similar to Earth. Mercury has a large core of liquid metal surrounded by a mantle of silica and a solid outer crust. In the case of Mercury, though, the core accounts for 42% of the planet, while Earth’s core is only 17%.Click to see full answer. In…
Scientists believe that Mercury has an interior composition similar to Earth. Mercury has a large core of liquid metal surrounded by a mantle of silica and a solid outer crust. In the case of Mercury, though, the core accounts for 42% of the planet, while Earth’s core is only 17%.Click to see full answer. In this regard, what makes up the surface of Mercury?The planet Mercury looks a little bit like Earth’s moon. Like our Moon, Mercury’s surface is covered with craters caused by space rock impacts. Mercury is the closest planet to the sun and the eighth largest. Mercury has a thick iron core and a thinner outer crust of rocky material.Furthermore, what is Mercury’s atmosphere made of? Mercury’s atmosphere contains small amounts of hydrogen, helium, and oxygen. It also has even tinier amounts of sodium, potassium, calcium, and magnesium. Some of the gas particles come from the solar wind. Others are made by radioactive decay or when micrometeorites smash into the surface. Moreover, what is Mercury made of rock or gas? Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.How cold is space? roughly 2.7 Kelvin
