Mantle : Is not liquid, but ductile or plastic, which means that some parts can flow under certain conditions and changes in pressure. Composed mainly of aluminum and silicates Crust : The outermost solid layer of earth. It is the lithosphere. Core : The innermost layers of the Earth. Mainly composed of nickel and iron Inner Core : Solid. Temperatures and pressures are extreme. Outer Core : A layer of liquid iron and nickel beneath the mesosphere. The only layer of Earth that is a...

Solar System - Science Olympiad Questions and Answers Rated A+ How did the terrestrial planets form? In the proto-Solar-Sytem, after the sun formed, the rest of the materials orbiting close around it began to clump together too. However, closer to the sun, lighter materials like gases blew away and only rocky material was left, causing the four terrestrial planets, and some of their moons, to form. What are the characteristics of Terrestrial Planets? Solid bodies with a core surrounded...

Meteors vs Meteorites correct answers Meteors go earths atmosphere and glow due to the friction of air heating them up (a shooting star). If it large enough and hold together to survive its plunge all the way to Earth's surface, it is called a meteorite. Meteoroids correct answers Small particles throughout the solar system. Upon entering Earth, they are designated either as a meteor or a meteorite (depending on how far they go after entering the atmosphere) Meteorite Falls correct an...
