GEOL 11040 Lecture 6: How the Earth Works 9/11/18

GEOL 11040 Lecture Notes - Lecture 7: Oceanic Crust, Surface Plate, Continental Drift

A tectonic plate is made up of both crust and rigid mantle lithosphere moving on top of the plastic asthenosphere. Plate boundaries are where the major

GEOL 11040 Lecture Notes - Lecture 9: Metamorphic Rock, Transform Fault, Subduction

Igneous rocks: interlocked minerals crystallized by lava. Sedimentary rocks: eroded or chemically precipitated grains that have been (re)deposited and

GEOL 11040 Lecture 10: How the Earth Works 9/25/18

GEOL 11040 Lecture Notes - Lecture 11: Mount St. Helens, Whin Sill, Continental Crust

Mineral content tells us about tectonic context. Grain size tells us about the cooling rate: Surface area of a sphere = 4 r^2. Very large crystals are

GEOL 11040 Lecture Notes - Lecture 12: Stratovolcano, Volcanic Ash, Fluorine

How volcanoes erupt (and how they can kill you) Mafic magmas: less viscous, often less volatile (gas+water). Multiple eruptions of runny sheet lava pro

GEOL 11040 Lecture Notes - Lecture 13: Columbia River Gorge, Volcanic Explosivity Index, Common Application

10 vei 4 (>0. 1 km^3) eruptions in last 10 years. 10 vei 5 (> 1 km^3) eruptions in the last 130 years. 10 vei 6 (> 10 km^3) eruptions in the l

GEOL 11040 Lecture Notes - Lecture 14: Clastic Rock, Denudation, Lithification

Igneous rocks form when mineral grains grow together and interlock while they crystallize from cooling magma. Sedimentary rocks are formed by compactio

GEOL 11040 Lecture Notes - Lecture 16: Clay Minerals, Cross-Bedding, Diamictite

Source: where weathering physically and chemically disassembles old rock. Sink: where clastic sediment and dissolved ions are reassembled into new sedi

GEOL 11040 Lecture Notes - Lecture 17: Facies, Stalagmite, Geochemistry

Due to weathering, transported clastic grains are modified. It is easy to tell an ice-born sediment apart from others because of its rare, angular form

GEOL 11040 Lecture 19: How the Earth Works 10/25/18

Igneous and sedimentary rocks transform into metamorphic rocks. Metamorphism: redistribution and transformation of rocks within the earth. Sedimentary:

GEOL 11040 Lecture 20: How the Earth Works 10/30/18

The water cycle and sediment transport are directly linked. Sediment is moved to a body of water. Leaves sediment behind in a place different from wher

GEOL 11040 Lecture Notes - Lecture 21: Epicenter, Seismometer, Foreshock

Magnitude is a factor, but there are a lot of more important things to know when predicting casualties. Ex: a magnitude 8 earthquake in haiti will be m

GEOL 11040 Lecture Notes - Lecture 22: Cascadia Subduction Zone, San Andreas Fault, Seismic Hazard

Small earthquakes can indicate where strain is accumulating. Can also indicate where a larger rupture is possible in the future. We only have a century

GEOL 11040 Lecture 23: How the Earth Works 11/8/2018

Behaves like fluid even if water is not involved. Lahar: mudflow made when a volcanic eruption melts snow and ice, then mixes with loose rock and sedim

GEOL 11040 Lecture Notes - Lecture 24: Sea Level

Rocks are different depending on the time or area in which they formed. Scotland used to be hot and arid - 350 million years ago. Oman used to be cover

GEOL 11040 Lecture Notes - Lecture 25: Closure Temperature, Absolute Dating, Crystallization

Cannot give exact ages or time frames. Come from measuring proportions of radioactive parent isotopes. Not necessarily more useful than relative, but m

GEOL 11040 Lecture Notes - Lecture 28: Source Rock

Something from the earth that we can put to use. Need to be able to extract and separate from the other materials around it. Some rocks are easier to e

GEOL 11040 Lecture Notes - Lecture 29: Road Salt, Magma Chamber, Crystallization

Metallic resources often come in the form of ores. Ore: rock composed of metal rich minerals. Can all become concentrated in their pure form. Geologica

GEOL 11040 Lecture Notes - Lecture 30: Last Glacial Maximum, Snowball Earth, Cryogenian

The earth"s climate has changed in the past. It has been much warmer in the past. Around 10 million years ago the earth was warmer with higher sea leve
