Igneous Rocks
Igneous rocks can be found around or in these.
What is a volcano?
These two things are required for metamorphic rock to form.
What is heat and pressure
What is the thinnest layer of Earth's interior?
What is the crust
Part of the crust that includes the ocean floor, which is thin, dense, and mostly made of basalt
What is oceanic crust
This causes sedimentary rock to form
What is pressure over time
This metamorphic rock forms from limestone and is often used in statues and buildings.
What is marble
Which two layers of Earth's interior are made of molten or partially molten rock?
What is the mantle and outer core?
What is contential crust?
Part of the crust that includes lan,d which is thick, less dense, and mostly made of granite
Visible layers can be seen in some sedimentary rocks. These layers are also called what?
What strata
Provide 2 examples of metamorphic rock.
What is
Slate
Marble
Schist
Gneiss
How do pressure and temperature change as you dive deeper into Earth's interior?
What is they both increase
A rock sample contains tiny pieces of other rocks that are cemented together
What is sedimentary rock
This can be found within sedimentary rock
What are fossils of dead plants and animals
These are rocks that can become metamorphic rocks.
What are sedimentary, igneous, and most metamorphic rocks?
Where is the lithosphere located?
What is the outer part of the Earth, including the crust and the upper part of the mantle.
What is the asthenosphere?
The layer under the lithosphere that flows very slowly, allowing tectonic plates to move on top of it
Explain crystal development in intrusive and extrusive igneous rock.
Intrusive: Magma cools slowly to form larger crystals.
Extrusive: Lava cools rapidly and forms small crystals and sometimes even no crystals at all
These are two ways to physically identify sedimentary rock
1 . Visible layers in the rocks
2. Seeing individual sediments that make up the rock
Metamorphic rocks are different from igneous rocks because they do NOT go through this process.
What is melting
How is the lithosphere divided?
HINT: What two type of plates?
What are oceanic and continental plates.
The breaking down of rock that creates sediment.
What is weathering
