What are the four steps of creating a sedimentary rock? (order does not matter)
1. Weathering 2. Erosion 3. Compaction 4. Cementation
What is the crust made out of?
Solid rock
What type of boundary causes subduction?
Oceanic plate and continental plate
What is the difference between a 'foliated' and 'non-foliated' rock?
Foliated rocks have layers and bands. Non-Foliated rocks do not have layers and bands.
What is the difference between magma and lava?
Magma is molten rock below the Earth's surface.
Lava is molten rock on the Earth's surface.
What is the mantle made out of?
Liquid rock or magma
What is uplift? What causes it?
Uplift is when two plates converge/go towards each other and go up.
How does convection move tectonic plates?
The magma from the mantle pushes the plates/crust floating on top
What is the difference between 'mafic' and 'felsic' rocks?
Mafic rocks are darker igneous rocks that a lower in silica. Felsic rocks are lighter igneous rocks that are higher in silica.
How is contact metamorphism different from regional metamorphism?
Contact Metamorphism: existing rock comes into contact with extreme heat
Regional Metamorphism: existing rock experiencing extreme pressure
What is the difference between the inner core and outer core?
The inner core is made of solid metal like iron and nickel. The outer core is made of liquid metal like iron and nickel.
What type of boundary causes mid-ocean ridges?
Divergent plate boundaries
How does magma create new crust?
When magma reaches the surface it becomes a new layer of crust
