where tectonic plates are diverging or converging. Amid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth’s crust in the interiors of plates‚ e.g.‚ in

Within the Earth System‚ chemical elements pass in cycles between different types of rock and sea‚ rock‚ and air. Plate Tectonics explains many Earth processes. Earth has a core‚ mantle‚ and crust.

The volcano we modeled was Erta Ale. Erta Ale is a active shield volcano. This volcano is located in Ethopia on the continent Africa. This volcano is on two divergent plates. It is the Afar rift that is causing the volcano to continue to be active today. The two plates that are responsible for this are the Nubian and the Somalian plates. Considering this is an active volcano‚ it does produce slow moving magma. The volcano doesn’t have a huge eruption it is small and builds up in the crater and causes

create new plates by splitting old ones apart. A rift is defined as a fracture in the earth’s surface that widens over time. A more technical definition for a rift is an elongated basin bounded by opposed steeply dipping normal faults. Geologists continue to debate exactly how rifting occurs. They do believe the process is so well displayed in East Africa‚ having given the new plate to be a name. The name is the Nubian Plate. The Nubian Plate makes up most of Africa‚ while the smaller plate that is

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

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
