Rock Cycle Flashcards
Rock
A solid made up of many different minerals
Sedimentary rock
Rocks that have been formed through the deposition of and solidification of sediment
Igneous rock
formed by a volcano or the solidification of molten rock
metamorphic rock
formed by extreme heat and pressure that changes the structure of rock
Rock cycle
The process in which rocks are continuously transformed between the 3 rock types
Sediment

Depositon
When sediments are deposited or dropped off in a different location
cementation
The hardening and sticking of mineral grains
Molten
Liquified by heat
Magma
