Rocks
A rock formed from layers of sediment that have been compacted and cemented over time
Sedimentary Rock
A rock formed from cooled magma or lava
Igneous Rock
Rocks formed by others rocks exposed to heat and pressure under earths surface.
Metamorphic Rocks
Tiny pieces of rocks and sand that have been broken off of other rocks
Sediment
The liquid form of a rock
Magma
The process that breaks down rocks by wind, rain, ice.
Weathering
Subduction
When a tectonic plate is pushed upwards over another plate at a convergent boundary.
Uplift
The process that creates magma....
The process that turns magma into an igneous rock...
Melting and Cooling
The pressing together of sediment by gravity over time.
Compaction
Rocks that are exposed to the energy from the sun are likely to experience...
Weathering and Erosion
Rocks that are exposed to the energy from Earth's interior are likely to experience...
Melting and/or Metamorphic Processes (Heat and Pressure)
What is the energy source for the creation of sedimentary rocks?
The SUN! and Gravity a bit
What is the energy source for the creation of Igneous rocks is?
Heat from earths interior
Rock A formed from small pieces of rock.
Rock B formed from liquid rock in a different place.
Are Rocks A and B the same or different types of rock?
They are different types of rocks
Giovanni and his family go on a trip and they drive over a mountain range. Giovanni wonders how the rock they see as they drive over the mountain range might be different when they drive back home next week. What would you tell Giovanni about how the rock will change?
The rocks would not change at all in a week.
A rock sample is igneous rock, but a student wonders if the material that it formed from was part of a sedimentary rock formation millions of years ago. Could the material for igneous rock come from sedimentary rock?
This is correct
On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. How did material from the rock formations turn into sand?
Weathering
Rock A and Rock B look similar.
Rock A was formed by compacted sediment.
Rock B was formed by metamorphic processes.
Are these two rocks the same type?
No they are not.
Matter (Elements, Atoms, Molecules)
What is energy's role in the creation of the different rock types?
Different sources of energy lead to different types of rocks.
What makes an observation good?
Good observations are detailed and specific.
On a planet with no sunlight, and with a core that has no energy. Would there be a rock cycle? Why or why not?
No, there would not. Energy is needed to change rocks.
What Native American tribe considers the "Devil's Tower" sacred?
The Lakota Tribe
How could an igneous rock formation underground be turned into sedimentary rock?
The formation needs to be uplifted, then weathered by energy from the sun creating sediments. The sediments are then compacted and cemented.
