The 3 rock types.
What are sedimentary, igneous, and metamorphic?
These rocks are formed from particles called sediments.
What are sedimentary rocks?
This type of rock is formed when a rock is under intense heat and pressure.
What is a metamorphic rock?
These rocks are formed from cooled magma or lava.
What are igneous rocks?
Every rock you see is or will be part of this.
What is the rock cycle?
Rocks are always changing, and are part of something called this.
What is the rock cycle?
Sediments accumulate in these over a long period of time.
What are layers?
Metamorphosis means this.
What is change?
Landforms that create igneous rocks.
What are volcanoes?
The process by which rock is broken down.
What is weathering?
All of the rocks of the world used to or will be this.
What is molten or melted rock or magma?
The process by which sedimentary rock becomes pressed together.
What is compaction?
Many metamorphic rocks have "bands".
What is foliation?
These rocks form from lava cooing quickly on the surface of the earth.
What are extrusive igneous rocks?
This is the hardest substance known to man.
What is a diamond?
Sediments are formed from this.
What is broken down rock?
These are remains or traces of plants and animals that lived long ago.
What are fossils?
When the sedimentary rock limestone becomes metamorphized, it turns into this rock.
What is marble?
These rocks are formed when magma cools slowly deep inside the Earth.
What are intrusive igneous rocks?
Sedimentary rock that is melted, cooled, and turned solid again would be this type of rock.
What is an igneous rock?
The lithosphere is broken into these.
What are tectonic plates?
The process by which water causes minerals to dissolve and harden the rock.
What is cementation and lithification?
Many metamorphic rocks can be found at these types of plate boundaries.
What are subduction zones?
This is a common types of intrusive igneous rock.
What is granite?
The transportation and settling of sediments.
What are erosion and deposition?
