the movment of sediment; removes pieces of Earth from one pace and builds land in another; agents: gravity, ice, wind, water

spin of Earth (or other Moon/planet) on its axis; takes 24 hours; causes day/night

a coastal breeze blowing at night from land to sea; caused by the difference in the rate of cooling of their surfaces

organizes the family of stars into a diagram; across bottom is star's temperature and side is star's absolute magnitude; a star's temperature and color depend on how big the star is

galaxy that is disc-shaped with a thin disk with long arms; gas and dust rotate around the central hub of the galaxy

a large group of stars, dust and gases in the universe held together by gravity

broken pieces of lithosphere; movement caused by convection currents in the asthenosphere

changes in ocean water levels that take place in regular pattern; controlled by pull of gravity between Moon and Earth; force of gravity of Moon pulls pulls ocean water away from Earth's surface

caused by uneven heating of Earth's surface; Occur within Earth's atmosphere and oceans. Produce wind and ocean currents.

the breaking down of rock into smaller pieces, called sediment; can create/change geographic formations; agents: gravity, ice, wind, water

moon phase that occurs when all of the Moon's surface facing Earth reflects light; the Moon appears completely lit

made of crust and upper part of mantle; broken into tectonic plates
