Revolution - one complete trip around the Sun which is 365 days = one year


Van Allen Radiation Belt - areas around Earth where particles from the Sun are trapped

Lithosphere - the hard outer layer of Earth

Crust - the rocky surface that makes up the top of the lithosphere and includes the continents and ocean floor

 Hydrosphere - Earth's water, found in continents and oceans, including the fresh water in ice, lakes, rivers and the underground water

Atmosphere - the blanket of gases that surrounds Earth

Solar System - the Sun and the objects that are traveling around it


Planets - any of the nine objects that travel around the Sun and shine by reflecting its light

Orbit - the path of a planet traveling around a star

Gravity - a force of attraction, or pull, between any object and any other objects around it.  Gravity is a property of all matter

Law of Universal Gravitation - Sir Isaac Newton gravity idea

Stars - large, hot balls of gas that is held together by gravity and gives off its own light

Constellations -  any of the patterns formed by groups of stars in the night sky.  To people in the past, these patterns looked like pictures of animals or people


Sun - star

Recycle - to reuse them

Raw Materials - material not yet refined, manufactured, or processed
