Two other names for onion weathering.
What is pressure release or dilatation?
100
The process by which oxygen is added to rock minerals.
What is oxidation?
100

What are bent trees and poles?
100
The thinnest, outermost part of the Earth's interior.
What is the crust?
200
Medium to coarse grained intrusive igneous rock that is rich in quartz and potassium feldspar. It is derived from felsic magma.
What is granite?
200
This is a process where rocks with joints in them break.
What is block disintegration?
200
These are what rocks take in during hydrolysis.
What are hydrogen ions?
200
The process where large sheets of talus move down slopes that have experienced freeze-thaw.
What is talus creep?
200
The depth at which the Earth's core extends to.

These are the void spaces found in rocks, sediments, and soil.
What is porosity?
300
Temperature in an area where freeze-thaw is common.
What is freezing point?
300
This element is found in rocks that are weathered by carbonation.
What is calcium carbonate?
300
This is the sudden movement of individual rocks or boulders down a steep slope.
What is rock fall?
300
This part of the Earth's interior is in a semi-molten state, its temperatures reach 5000 degrees Celcius, and is another name for the asthenosphere.
What is the lower mantle?
400
The angle at which the strata of sedimentary rocks are tilted at.
What is the dip of a sedimentary rock?
400
This is an example of industrial action that involves cause biological weathering.
What is acid rain?
400
The name for the process that involves the extraction of metallic cations from rocks and minerals by chelates.
What is chelation?
400
This is the movement of saturated, large rocks over smaller rocks.
What is rock slump?
400
This man was a geologist who discovered a discontinuous between the upper mantle and the oceanic crust, also referred to as the Moho Discontinuity.
Who is Mohorovicic?
500
This rock is an example of a hypabyssal igneous rock that cools and solidifies close to the Earth's surface while still within its interior.
What is quartz?
500
This means the physical wearing and grinding of a surface through friction and impact by material carried in air, water, and ice.
What is abrasion?
500
During hydrolysis, felspars are broken down into these two substances.
What are potassium hydroxide and acids?
500
The sudden movement of large quantities of loosened surface rocks down a slope carrying with it everything.
What is landslide?
500
This discontinuous layer is located between the inner core and the outer core.
What is the Lehmann Discontinuity?
