15-20 million years. What Is It? Scientists have learned that the Earth’s crust is fractured into a series of "plates" that have been moving very slowly over the Earth’s surface for millions of years. Two of these moving plates meet in western California; the boundary between them is the San Andreas fault. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east)‚ causing earthquakes along the fault. The San Andreas is the "master" fault of an intricate fault

1. Summarize advances over time in determining the age of the Earth‚ including the importance of the discovery or radioactivity. Herodotus counted layers of earth near the Nile River in 450 B.C.E. The Bible was used in the Middle Ages to compute the age of the Earth. The 18th and 19th centuries brought a more scientific look into determining the age of the Earth by studying the salinities of the oceans‚ the rates of sedimentation‚ and models of cooling of different materials in order to calculate

Introduction I’m going to talk about a tsunami which hit many places in Asia and some parts of Africa which left many homeless and Thousands dead. A tsunami is a giant wave of series of waves usually caused to be a volcanic eruption or earthquakes o the seabed. As the Tsunami travels through deep water‚ the wave may

side because the mountains block the flow of water to a certain degree. The mountains that define the whole park and offer a variety of life‚ along with the beauty that comes with it‚ were formed by the collision of tectonic plates. The North American plate and the Pacific Plate have been colliding for millions of years and they have shaped the unique terrain of Denali National Park. Glaciers have also left their mark on the land‚ making craters and valleys. The Park is made up of many types of rocks

were hooked up to IV’s by relatives. Scientists believe that mostly earthquake occurs due to the movement of plates and this theory is known as plate tectonics. This says that earth’s outer crust has ten rigid‚ hard and large plates‚ twenty small plates. These plates are continuously moving on the hot and soft rock of mantle slowly. This movement causes collision among other plates which further causes stress on the lithosphere. The stress becomes enough to shift or break crust. Now the stress

temperature and crystallizes in caverns deep within the earth. The molten rock cools quite slowly over time‚ which allows the crystals to grow and develop inside the molten rock. Granite is transported to the surface of the earth by plate tectonics. The collision of continental plates moves the granite from deep within the crust of the earth to the surface. Granite is found in Ireland in the Wicklow Mountains. (http://www.talktalk.co.uk/reference/encyclopaedia/hutchinson/m0015252.html) Granite is distinguished
