Rocks 1
The process of sediments becoming "glued" together.
What is cementation?
Formed by heat and pressure while buried deep below Earth's surface.
What is metamorphic rocks?
Rocks formed under great pressure without heat.
What are sedimentary rocks?
A model that describes the formation, breakdown, and reformation of a rock.
What is the definition of the rock cycle.
The process/es that help/s form existing rock into metamorphic rock.
What is heat and pressure?
The process/es that help/s form existing rock into sedimentary rock?
What is weathering and erosion and compaction?
A rock that may contain fossiles.
What is sedimentary rock?
A rock with banded (ribbon-like) layers.
What is metamorphic rock?
Basalt, obsidian, and granite are examples of this type of rock.
What are igneous rocks?
This can be caused by weather (rain, ice, wind), chemical changes, and living things (plants).
What is weathering?
Cooling and hardening is the solidification of molten rock material.
What is the Igneous Process?
Compaction occurs when sediments are deeply buried, placing them under pressure because of the weight of overlying layers.
What is the Sedimentary Process?
Heat can change sedimentary, igneous, or another older metamorphic rock.
What is the Metamorphic Process?
These rocks may have large holes where gas was trapped, glassy in appearance, and large crystals.
What are Igneous Rocks?
Their movement creates extreme heat and pressure below the Earth's surface.
What are tectonic plates?
This describes the breaking down of sedimentary rocks into sediments.
What is weathering?
This rock may look like glass when cooled fast.
What is Igneous rock?
This molten rock material is found on Earth'surface.
What is lava?
This molten material is found way below the Earth's surface.
What is magma?
If this gets trapped during the Igneous rock process, holes will be formed.
What is gas?
Deposition, erosion, wind, water, gravity, and ice.
How sediments are moved?
Gneiss, marble, and slate.
What are types of Metamorphic rock?
Sandstone and limestone.
What are examples of Sedimentary rock?
