A
How are igneous rocks produced?
Melting and cooling
-1
Give three examples of rock and state which kind each are.
Basalt (igneous), Granite (igneous), slate (metamorphic), etc
+2
What is the difference between a slow scale geological process and a fast/catastrophic scale geological process?
Plate motion vs volcano
-5
At about what speed do the tectonic plates move?
About as fast as your fingernails grow.
+5
What are three features of the Earth's crust?
Continental crust - floats, buoyant, etc
Oceanic crust - dense, sinks, etc
+2
What are the three types of tectonic plate movements?
Divergent, convergent, transform
-5
How are sedimentary rocks produced?
Weathering and erosion
-2
What are the layers in rocks called that scientists use to tell how old that part of the crust is?
Varves
-5
What are three features of the Earth's mantle?
Liquid, hot, currents, etc
+1
What are the two types of convergent plate movements? Describe both
Subduction - oceanic crust dives beneath continental
Collision - two continental crusts push against each other
-1
Describe a divergent plate movement and give an example.
Plates move away from each other (mid Atlantic ridge)
+5
What is the difference between a small scale geological process and a large scale geological process?
landslide vs plate motion
-8
How are metamorphic rocks produced?
Heat and pressure
-3
What type of rock is the oceanic crust mostly made of?
Basalt
-10
Describe a transform plate movement and give an example.
Two plates rub against each other (San Andreas Fault)
-2
What is Pangea?
The supercontinent from before the continents all broke apart.
+4
What are three features of the Earth's core?
Solid, hot, lots of pressure, etc
+3
What is the difference between magma and lava?
Magma is beneath the earth's crust and lava is on the surface.
+3
What are the three types of rock?
Igneous, sedimentary, and metamorphic
-4
What are the two different kinds of igneous rock? Explain how both are made.
Intrusive - formed beneath the Earth's crust
Extrusive - formed on the surface of the Earth
+1
Draw a diagram of the Earth's layers.
+4
What type of rock is the continental crust mostly made of?
Granite
+10
Define a geological process.
Something that happens on the Earth's crust that impacts the way it is structured.
-3
What are tectonic plates?
Large slabs of the Earth's crust that slowly move around.
+5
Draw the rock cycle.
