ESS 101 INTRO TO GEOLOGY - University of Washington _ Laboratory 4: Volcanoes, Plutons, and IgneousRocks. Fall 2022. Score for this attempt: 11.9 out of 15. Igneous rocks form when magma cools, either slowly underground or rapidly at earth’s surface (i.e. near volcanoes). Magma cooling processes affect the size of crystals in igneous rocks. Bigger crystals form in slow-cooling, underground magma chambers, and smaller crystals form in fast-cooling lava flows/eruptions. To recognize eight common...

Volcanoes: Ring of Fire - answer-Exists because of spreading of sinking plates at plate boundaries interact with other Earth materials to produce rocks. Volcanic Vents - answer-An opening through which lava and other volcanic materials are extruded onto the surface. Volcanoes: Decompression Melting: - answer-Overlying pressure exerted on hot rock within the asthenosphere is decreased. Magma will begin to form even though the temperature is constant. Volcanoes: Decompression Melting: Hot...

What is the apparent dip of a bed? - ANSWER-Apparent dip of a bed or plane is the inclination of that bed or plane in a direction not perpendicular to strike. What is a fold line and how is it used? - ANSWER-The fold line is a hinge line along which a vertical cross section may be constructed and then flattened out to a horizontal or map view. It is used to represent the subsurface along any given line in a map view. It need not be perpendicular to strike. What is the angle and side relati...

What is the angle and side relationships for the sin equation? - ANSWER-sinα = opposite side/hypotenuse What is the angle and side relationships for the tanget equation? - ANSWER-tanα = oppo...

What does the "Single-Point Resistivity Log" show and what area is it limited to? - ANSWER-A log that measures the resistivity using 2 electrodes and having a limited area of investigation of from 5 to 10 times the electrode diameter What is the "Area of Influence" of a well? - ANSWER-The area within which the potentiometric surface is lowered by withdrawal or raised by injection, of water through a well Define aquifer - ANSWER-A geologic unit that is saturated and sufficiently permeab...

This course explores volcanic processes, and their climatic, environmental and human consequences. It begins by probing what goes on beneath a volcano – the physical and chemical evolution of magma chambers; why bubbles are so important in triggering and driving eruptions, and how dramatic (and deadly) switches in eruptive style can occur. It then examines eruption clouds and ash deposits, and how the latter provide a record that can be combined with tree-ring, ice core and archaeological evid...
