One factor that determines the size of crystals is the rate at which magma or lava ________. cools
Large crystals form when magma cools ___________ deep below the surface. slowly
When magma erupts to the surface, it is called ______. lava
A solid mixture of 2 or more minerals and other materials rock
This type of rock forms from the cooling of magma or lava (Latin for "fire"). igneous
This type of rock forms when particles of other rocks or the remains of plants and animals are pressed and cemented together. sedimentary
This type of rock forms when an existing rock is changed by heat and pressure. metamorphic
type of igneous rock that forms from lava that erupted onto Earth's surface resulting in fine grain or small crystal rocks. extrusive
This type of igneous rock forms when magma hardens beneath Earth's surface resulting in large grain or large crystals. intrusive
movement of rock fragments or particles by wind, water, ice, or gravity erosion
process that presses sediments together compaction
process in which dissolved minerals crystallize and "glue" particles of sediment together cementation
small, solid pieces of rocks or other materials sediments
process that breaks down rock and other substances of Earth's surface weathering
process in which particles or sediments are laid down deposition
process by which sedimentary rocks are formed lithification
how metamorphic rocks are formed heat and pressure
how igneous rocks are formed melt into magma and then cools into igneous
What is sedimentation? Another word for deposition
Why can fossils only form in sedimentary rocks? They would melt in igneous rocks and be crushed too much with metamorphic rocks. Sedimentary rocks allow layers to pile on top of the creature after it dies so that fossils can be made.
Where is the oldest layer of rock located? at the bottom (or deeper in the earth)
metamorphic rocks with lines foliated
metamorphic rocks without lines non-foliated
