100

The plate boundaries/tectonically active regions that igneous rocks are formed at

Convergent, divergent, and hot spots

100

The two types of weathering that happen to sedimentary rocks

Chemical and physical

100
The state of matter of the Earth's mantle

Solid

100

The color generally associated with the most ultramafic of rocks and then the most felsic of rocks.

Green and pink

100

The three types of plate boundaries

Divergent, convergent, and transform

200

The two types of igneous rocks and their general definitions

Intrusive - formed beneath the surface and cooled slowly

Extrusive - formed at the surface and rapidly cooled

200

The location along a stream in which large clasts are deposited

Upstream/Near the source

200
These two reasons are the primary causes for melting of the mantle

Decompression and addition of water

200

According to Bowen's Reaction Series, this type of rock dissolves and breaks down the fastest

(Bonus 200 points for explaining WHY!)

Mafic, because of the looser connections in the silica tetrahedral network compared to felsic.

200

This occurs at the Mid-Atlantic ridge and "grows" the oceanic crust

Seafloor spreading

300
The process of incorporating surrounding country rock into the melt

Assimilation

300

Each stage of the formation of a sedimentary rock

Weathering, Erosion/Transportation, Deposition/Sedimentation, Burial, Diagenesis/Lithification

300

The only layer of the Earth where the geotherm is to the right of the melting curve

The outer core

300

The continual transformation of Earth materials from one rock type to another

The rock cycle

300

This plate boundary has no metamorphic or igneous activity

Transform boundary

400

Magmas that crystallize in the crust or erupt as lavas at the surface are initially formed by melting this layer of the Earth

The mantle

400

The two sediment types

Clastic sediments and chemical/biochemical sediments

400

This mineral is the most common one in the Earth's mantle

Olivine

400

The two factors that control the properties of rocks

minerals in the rock, formation of the rock

400

How we know the reversal of the Earth's magnetic field

Basalt in the seafloor

500

How you would expect the composition of igneous rocks to change vertically through the continental crust

More mafic in the lower crust and becoming more gradually more felsic in the shallower crust

500

This sediment quality increases downstream in water transport

Sediment maturity

500

Average thickness of the lithosphere and the continental crust, respectively.

About 100km and 40km.

500

This element would most likely occur in an orthoclase feldspar (KAlSi3O8)

Na/Rb

500

This plate boundary is associated with intrusion of granite at depths and explosive andesitic volcanic activity

Convergent boundary
