Rock Types
A sedimentary rock is formed when....
A sedimentary rock is formed when energy from the sun weathers it down into sediment. The sediment is then compacted and cemented.
True or False: A sedimentary rock can turn into an igneous rock.
True.
What kind of rock is found at the Great plains?
Sedimentary
What day is verbals?
December 14th
An Igneous rock is formed when....
Magma cools down to form an igneous rock.
Describe how an igneous rock would turn into a sedimentary rock.
The rock would be weathered down into sediment (loose rocks) where it would then be compacted and cemented together over time.
What kind of rocks are found in the Rocky Mountains?
Igneous and Metamorphic
How long do you need to talk for in verbals?
Between 2 and 3 minutes
What type of rock forms at a plate boundary under intense heat and pressure?
A metamorphic rock.
Define subduction.
The process where a rock is taken down under the surface of the Earth's crust by a plate boundary.
Which rock formation is older, the Rocky mountains or the great plains?
Rocky Mountains
True or false: The judges will be other teachers.
False.
What type/types of rocks form from the energy of the sun?
Define uplift.
The process where a rock is taken upwards towards Earth's surface by a plate boundary.
Explain how the rocks from the Rocky mountains traveled to the Great plains.
The igneous rocks of the Rocky Mountains were weathered by the sun and rain until they were broken down into sediment and were washed down into the Great Plains where they were cemented and compacted into sedimentary rock.
When will you get your score for verbals?
Right after you complete your verbal, the judges will calculate your score.
What kind of energy do igneous and metamorphic rocks use?
Metamorphic and igneous rocks use energy from the Earth's interior.
Describe the life cycle of a rock going from sedimentary to igneous.
The rock is subducted beneath the surface where it encounters extreme heat and magma. The rock is melted down and then uplifted by the plates where it will eventually cool down and become igneous.
Explain why The rocks of the great plains (sedimentary) could not turn into the rocks of the Rocky Mountains (igneous)
In order for a sedimentary rock to turn into an igneous rock there must be a plate boundary between them to subduct the sedimentary rock so that it may get hot enough to melt.
Name the three parts of the verbals question.
1. Name the three types of rock
2. Describe how the rocks transform into each other.
3. Explain how the rock of the Rocky Mountains and the Great Plains formed.
