Rocks and the Rock Cycle
A natural, sold mixture of minerals or particles.
What is a rock?
Igneous rock forms when these two things happen.
When lava cools and crystalizes?
Sedimentary rocks are most likely to form in this environment.
What is a body of water on Earth's surface?
Sedimentary rock that forms when minerals crystallize directly from water.
What is chemical rock?
Metamorphic rocks form when existing rocks are exposed to these things.
What is extreme heat and pressure or the addition of chemical fluids?
The minerals or bits of other materials in a rock.
What are grains?
The type of igneous rock that forms when volcanic material erupts and cools and crystallizes on Earth's surface.
What is extrusive rock?
Rock material that forms when rocks are broken down into smaller pieces or dissolved as rocks erode.
What is sediment?
Sandstone and conglomerate are this type of rock.
What is clastic?
Metamorphic rocks are classified into these two groups based on texture.
What are foliated and nonfoliated rocks.
The ways that rocks can be classified.
What is size, shape, and chemical composition?
The type of igneous rock with large interlocking crystals that forms as magma cools underground slowly.
What is intrusive rock.
The result of pressure on loose sediment. It forces fluids out of sediment.
What is compaction?
Chemical limestone, rock gypsum, and rock salt are this type of sedimentary rock.
What is chemical rock?
These metamorphic rocks contain parallel layers of flat and elongated minerals.
What are foliated rocks?
The three major groups of rocks.
What are igneous, sedimentary, and metamorphic?
Extrusive or Intrusive? Granite
What is intrusive?
Sedimentary rock that forms from broken pieces of minerals and rock fragments.
What is clastic rock?
Coal, chert, and fossiliferous limestone are this type of sedimentary rock.
What is biochemical rock?
These metamorphic rocks have mineral grains with random interlocking texture. They are usually uniform in color. One example is marble.
What is nonfoliated rocks?
The series of processes that change one type of rock into another type of rock.
What is the rock cycle?
Extrusive or Intrusive? Obsidian and pumice.
What is extrusive?
Sedimentary rock that forms from organisms or the remains of organisms.
What is biochemical rock?
The processes involved in forming sedimentary rock.
What is erosion, transportation, deposition, compaction, cementation?
This metamorphism is the formation of metamorphic rock over very large areas.
This metamorphism occurs when magma comes in contact with existing rock.
What is regional metamorphism?
What is contact metamorphism?
