Chapter 1: An Introduction to Geology What is geology‚ and what is the difference between physical and historical geology? Geology is the scientific study of the Earth and its major systems Physical Geology is the Study of the Earth’s composition. structure‚ and the processing that shape it Historical Geology is the Study of Earth’s history and the history of life With respect to why we study geology‚ in class I cited three areas of benefit to humanity where geologic knowledge is needed.

from Mt. Olympus. Zeus was the deemed the king of the Gods and Hera his queen. This pantheon of twelve Gods and Goddesses are considered the Olympians‚ representing primary aspects of life such as war‚ love and death. Six male gods exist in the pantheon‚ two (Zeus and Poseidon) were born of Titan Gods themselves and overthrew their father to rule the universe. Hades‚ their brother‚ also fought by their side‚ but after the victory he was given rule of the Underworld‚ so did not sit atop Mt. Olympus

EOSC 114: Volcanoes Notes from Web Notes Lesson 1: Why Do Volcanoes Have Different Characteristics? A. Formation of Lava Magma is formed by melting preexisting rock in Earth’s interior For magma to rise through crust it must be: (1)less dense than the crust (2) runny enough to flow (3) hot enough to stay liquid Magma that cools to form solid rock = lava B. Composition of Magma/Lava Magma is composed of various proportions of: Oxygen‚ Silicon‚ Aluminum‚ Iron‚ Calcium and Potassium Mineral –

interior of the Earth holds a tremendous store of heat released primarily from the ongoing decay of radioactive elements. Earth’s internal energy flows unceasingly toward the surface. * Over short time span: released as eruptions from volcanoes and by earthquakes. * Over long intervals of geological time‚ the flow of internal energy has produced continents‚ oceans and atmosphere. * On a planetary scale‚ this outward flow of internal energy causes continents to drift

largest of the Hawaiian Island Shield volcanos. Because of this great size the volcano actually slumped 42‚650 feet below sea level‚ not only is Mauna Loa is the largest in the Hawaiian chain‚ it is also the largest on earth. Of all the Hawaiian volcanoes‚ Kilauea is the most active with its current eruption going on since 1983. Mauna Kea‚ though overall smaller than Mauna Loa‚ actually has a high elevation. Its smoother profile is due to it being estimated at over a million years

arc-trench systems in the country: the Kuril Trench‚ Japan Trench‚ Izu-Bonin Trench‚ Ryuku Trench (partially pictured)‚ and Nankai Trough. Here‚ we can observe that the trenches (yellow line) are parallel to the volcanoes (red dots). You can almost draw a straight line to connect all the volcanoes. Moreover‚ the data above is evidence of the presence of subduction zones wherein the collision of two plate boundaries causes the denser plate to sink below the less dense plate into the asthenosphere.
