Rocks
The name of the process that creates new rocks and breaks down or changes old rocks.
What is the rock cycle.
When heat and pressure are added to an existing rock, this rock forms.
What is metamorphic rock.
The age of a rock in number of years since it formed.
What is absolute age.
This is the layer where you would find the youngest rock.
What is the top layer.
This is the youngest layer.
Layer B
This rock is made up of sediment, minerals, dead plants and animals, and bits of other rocks.
What is sedimentary rock.
When a rock is melted and cooled, this rock forms.
What is igneous rock.
The age of a rock in relation to the other rocks around it.
What is relative age.
These form when lava hardens on the surface.
What is extrusions.
This is a fault.
What is F
This rock can only be made deep in Earth under great heat and pressure.
What is metamorphic rock
When rock is broken down into sediments.
What is weathering.
This layer is most vulnerable to erosion.
What is the top layer.
These form when magma cools and pushes into the bodies of rocks and hardens.
What is an intrusion.
This is an intrusion.
What is A.
This rock forms when lava quickly cools. This causes the rock to have fine grains and small crystals.
What is extrusive rock
When rock is moved by wind, water, and ice.
What is erosion.
This uses radioactive dating to find the age of a rock.
What is absolute dating.
This is the layer where you would find the oldest rock.
What is the bottom layer.
This is the youngest layer.
What is B.
This rock forms when lava slowly cools. This causes the rock to have coarse grains and large crystals.
What is intrusive rock.
When sediment settles out of the wind, water, and ice.
What is deposition.
This states that the deeper down you dig, the older the rock layers get.
What is Law of Superposition.
This is a crack in the Earth's crust.
What is a fault.
This is the oldest layer.
What is Q.
