Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
The way light reflects off of a mineral (metallic or non-metallic).
What is luster?
The outermost layer of Earth where we live.
What is the crust?
The theory that explains how Earth’s plates move.
What is plate tectonics?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
These are two ways that sediments are formed.
What is weathering and erosion?
The scale that is used to measure the hardness of minerals
What is Moh's Hardness Scale
The thickest layer of Earth located beneath the crust.
What is the mantle?
The type of boundary where plates move apart.
What is a divergent boundary?
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white/black tile.
What is streak?
This layer is made of liquid iron and nickel and creates Earth’s magnetic field.
What is the outer core?
The type of boundary where plates collide and form mountains.
What is a convergent boundary?
This type of igneous rock is black with a glassy texture. We looked at it in class.
What is obsidian?
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
This property describes how a mineral breaks unevenly or irregularly.
What is fracture?
This layer is solid due to extreme pressure despite very high temperatures.
What is the inner core?
This supercontinent existed before breaking apart into today’s continents.
What is Pangea?
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
The type of sedimentary rock that can contain fossils.
What is organic or biochemical sedimentary?
You can see this property just by looking at a mineral. Many minerals can be several of these.
What is color?
Name all four layers of Earth in order from outermost to innermost.
What are crust, mantle, outer core, inner core?
What type of boundary is most associated with earthquakes, where plates slide past each other?
What is a transform boundary?
