Minerals
In some minerals, chemical composition can vary within a certain range depending on this.
Temperature
It's the breaking down of rocks by phsical and chemical means.
Weathering
The force that causes materials to move downslope during mass movement.
Gravity
It's a shallow depression caused by wind erosion.
Deflation Blowout
List 3 types of plate boundaries.
Divergent, convergent and transform
This approximately the number of minerals that make up the Earth's crust.
8-10
The most common type of sedimentary rocks; formed from the abundant deposits of loose sediments that accumulate on Earth's surface.
Clastic Sedimentary Rocks
It's the slow, steady, downhill flow of loose, weathered Earth materials, especially soils.
Creep
The process that occurs when particles such as sand rub against the surface of rocks or other materials.
Abrasion
List the 3 types of volcanoes.
Shield, Composite (Stratovolcanoes) and Cinder Cone
These minerals form from the evaporation of the liquid in which they were dissolved.
Evaporites
This occurs when high temperature and pressure affect large regions of Earth's crust.
Regional metamorphism
It's the type of mudflow that occurs after a volcanic eruption.
Lahar
Thick, windblown silt deposits.
Loess
They are individual volcanic mountains produced by hotspots under the ocean floor.
Seamounts
They are compounds of oxygen and a metal, such as hematite (Fe2O3).
Oxides
Rocks formed as magma cools and crystalizes.
Igneous Rocks
It's creep that usually occurs in regions of permafrost.
Solifluction
The breaking off of pieces of rock when a valley glacier moves.
Plucking
It's the amount of damage done to structures as a result of an earthquake and measured by the modified Mericalli Scale.
Intensity
5 characterristics geologists use to identify minerals.
Luster, hardness, break, streak, color, special properties, texture and specific gravity.
Explain what causes holes to form in igneous rocks.
Gasses escape as they cool.
List the four factors that influence mass movement.
Weight, resistance to sliding, a trigger, water
It's unsorted rock, gravel, sand and clay deposited by glaciers.
Glacial Till
The three areas in which Wegener collected evidence to support his hypothesis of continental drift.
