Name the three plate boundaries and use arrows to describe each.
convergent --><-- divergent <-- --> transform ----> <----
200
The property that causes a mineral to glow under ultraviolet light
fluorescence
200
This coarse-grained igneous rock is formed when magma cools beneath the Earth's surface.
intrusive igneous rock
200
These two things cause metamorphic rocks to form.
heat and/or pressure

You can see this mineral property just by looking at the mineral. Many minerals can be several of these.
Color
300
Two continental plates colliding will cause these to form
mountains
300
What property describes the way light reflects off the surface of a mineral?
luster
300
sedimentary rock can be formed when sediments are pressed together to form layers
compaction
300
metamorphic rocks that look like the minerals were fused together randomly
non-foliated
300
the crust and the upper mantle
lithosphere
400
the idea that all the land masses were once a supercontinent that slowly moved away from each other (2 answers)
Pangaea and continental drift
400
when a mineral splits along smooth, flat planes and surfaces
cleavage
400
What is the difference between magma and lava?
magma - molten rock within Earth's crust lava - molten rock at or above Earth's crust
400
What happens if an igneous rock weathers and erodes? What rock will it turn into?
sedimentary rock
400
List three examples of constructive forces and three examples of destructive forces found at plate boundaries.
constructive - mountains, trenches, volcanoes, volcanic islands, seafloor spreading, mid-ocean ridges destructive - earthquakes, volcanoes, subduction zones, faults
500
location where plates with different densities collide and the denser plate sinks under the less dense plate
subduction zone
500
the hardest known mineral
diamond
500
Which rocks are most likely to have organic material?
sedimentary rocks
500
forces deep inside Earth and at the surface produce a slow process that builds, destroys, changes, and recycles rocks.
rock cycle
500
What determines the size of crystals that form within igneous rocks?
rate/speed of cooling; how fast or slow the molten rock cools
