How do they do it?
100
Growth rings in fossil oyster shells tell us this.
What is how old the oysters were when they died.
100
Solid material that consists of rocks, minerals, and organic particles.
What is sediment.
100
This is what rocks are made from.
What are minerals.
100
This type of rock forms when pieces of rock are pressed and cemented together.
What is Sedimentary.
100
This is a layer of sedimentary rock.
What is strata
200
A fossil found in specific layers of rock all over the world.
What is an index fossil.
200
This is the process that causes rocks to break apart and/or get softer.
What is weathering.
200
This is the continuous process by which rocks are created, changed from one form to another, destroyed, and then formed again.
What is the rock cycle.
200
This type of rock forms when magma or lava cools.
What is Igneous.
200
This is the process of turning metamorphic rock into igneous rock.
What is melting-magma-cooling-igneous.
300
Marine fossils found on the top of a mountain would indicate this.
What is that mountain was once the ocean floor.
300
A type of weathering in which surface soil and rock are worn away through the action of glaciers, water, and wind.
What is erosion.
300
Naturally occurring, individual crystals of all the same stuff are known as this.
What are minerals.
300
This type of rock forms from other rocks that are changed by heat and pressure.
What is Metamorphic.
300
This is the process of turning sedimentary rock into metamorphic rock.
What is buried-heat-pressure.
400
This is the science of determining the order of past events.
What is relative dating.
400
The geological process in which wind, water, and ice transport sediments, soil and rocks and add them to a landform or land mass.
What is deposition.
400
Crystallization of magma or lava and crystallization of materials dissolved in water.
What are the two ways minerals form.
400
The two types of rock that require heat to form.
What are Igneous & Metamorphic.
400
This is the process of turning sedimentary rock into igneous rock.
What is melting-magma-cooling-igneous.
500
In any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom.
What is the Law of Superposition.
500
This is what is created when magma cools and solidifies before it reaches the surface.
What is an igneous intrusion.
500
The crystal size of minerals depends on this.
What is how fast the hot material cools.
500
The two types of rock require pressure to form.
What are Metamorphic & Sedimentary.
500
This is the process of turning metamorphic rock into sedimentary rock.
What is weathering-erosion-compaction.
