Introduction to Geology GEOL-101 Midterm 1 Review Based on the textbook: Understanding Earth‚ 6th Edition‚ by Grotzinger and Press CH 1: earth system Summary The human creative process‚ field and lab observations‚ and experiments help geoscientists formulate testable hypotheses (models) for how the Earth works and its history. A hypothesis is a tentative explanation focusing attention on plausible features and relationships of a working model. If a testable hypothesis is confirmed by a large

Nelson Tsunami This page last updated on 02-Jul-2012 Up until December of 2004‚ the phenomena of tsunami was not on the minds of most of the world’s population. That changed on the morning of December 24‚ 2004 when an earthquake of moment magnitude 9.1 occurred along the oceanic trench off the coast of Sumatra in Indonesia. This large earthquake resulted in vertical displacement of the sea floor and generated a tsunami that

There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur

It was caused by the a fault rupture on the subduction zone of the Indian (Eurasian) plate and the Sunda plate (Indonesian plate). It has been recorded that the epicentre was 20km under the sea‚ and 250km off the the coast if Indonesia‚ near the city of Banda Ache. Primary Effects: The tsunami

For example‚ as the Atlantic Ocean grows wider with the spreading of the African Plate away from the South American Plate‚ the Pacific sea floor is being consumed in deep Subduction trenches over thousands of miles away. In plate tectonics‚ a convergent boundary is an actively deforming region where two (or more) tectonic plates collide. As a result of pressure‚ friction‚ and
