ATMOSPHERE : the layer of gases surrounding a planet that is held in place by gravity
CRUST : the thin, solid, outermost layer of Earth
SEDIMENTARY: rock formed when particles of other rocks are deposited in layers and cemented together
OUTER CORE : the outer layer of Earth’s core; surrounds the inner core and is made of liquid nickel and iron
ROCK CYCLE : the cycle through which Earth’s rocks change from one type into another over time due to various Earth processes; creates changes in mineral compositions and physical structures
GEO SPHERE : portion of the system of Earth that includes Earth’s interior, rocks and minerals, landforms, and the processes that shape Earth’s surface
MAGMA : melted, or molten, rock material beneath Earth's surface; cools slowly to form rocks with larger crystals
HYDROSPHERE : all the water on Earth’s surface; includes all water sources above and below the surface
MANTLE : the solid layer of Earth between the crust and the core; made of dense silicates
PRESSURE : force exerted on matter through contact with other matter
LITHOSPHERE : another name for the geosphere
METAMORPHIC ROCK : rock formed deep underground due to heat and pressure
CEMENTATION : when compacted sediments stick together and turn into rock
SEDIMENT : Earth material that is broken down by processes of weathering; can be eroded and deposited by the agents of water, wind, ice, and gravity
OCEANIC CRUST : contains the oceans and the ocean floor
LAVA : molten rock, or magma, that has reached Earth's surface by volcanic reaction
MELTING : when a sample of matter changes from a solid to a liquid
BIOSPHERE : the sum of all living matter on Earth
WEATHERING : the mechanical or chemical processes by which gravity, wind, water, and ice breaks rocks into smaller pieces
COMPACTION : when rock particles or sediments are pressed together or packed down by gravity and the pressure of overlying rock layers
IGNEOUS ROCK : rock formed when lava or magma cools, forms crystals, and solidifies
INNER CORE : the sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core
