1. Compare the age of igneous rock found near the mid-ocean ridge with that of igneous rock found farther away from the ridge. The ages of the igneous rock found near the mid-ocean ridge was younger than the igneous rock found farther away from the ridge. This is because of convection currents. Magma rises because it is less dense. It is forced out of the ridge‚ it spreads apart‚ and when it cools‚ it becomes new seafloor. This is why newer seafloor (igneous rock) is younger when it is closer to

stuck. With the pressure and tension build up‚ rocks in the plates break and results in earthquakes. Spreading Mid ocean ridges are places where the Earth’s tectonic plates spread apart from each other as hot magma emerges from the mantle and oozes forth as lava to fill the gap constantly created by the plate separation. This is called diverging. As it cools it forms new ocean floor crust. This process is known as sea floor spreading. Colliding When two continental plates move towards each

A few of the more important laws governing the way water rights are allocated today are the Colorado River Compact‚ Boulder Canyon Project Act of 1928‚ Mexican Water Treaty of 1944‚ and Upper Colorado River Basin Compact of 1948. The Colorado River Compact was an agreement made by all seven states in 1922 (US Department of the Interior‚ 2008). This was responsible for dividing the basin into Upper and Lower basins and appropriating half of the water

11/20/13 Earth Space Science Plate Tectonics Theory Plate tectonics is the theory that the outer rigid layer of the earth is divided into a couple of dozen plates that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. Plate Tectonics is cause by convection currents in the mantle of the Earth. This theory was originally called continental drift. The theory of “Pangea” that is the continents were connected was Alfred Wegener. The age of the sea floor is

Darling Basin is facing many environmental challenges and issues; including salinity. The Murray Darling Basin is one of the largest catchments in the world but it is also one of the driest (Mdba.gov.au‚ 2015). The basin is world-renowned with it being one of Australia’s most iconic and oldest river systems; the Murray Darling is over 350 million years old (Mdba.gov.au‚ 2015). The Murray Darling Basin is located in the South- East of Australia (refer to appendix A). The Murray Darling Basin is highly

This study utilizes thirty-four intersecting‚ multi-channel regional 2D seismic lines from the Offshore Sirte Basin‚ Libya‚ to assess the structure and stratigraphy from the Miocene to the Quaternary. The structural regime has been reviewed in relation to regional tectonic events in the Western Mediterranean. The structural style of the study area is characterized by normal faults with a variation in throw direction and fault-related folds. The major structural trend is NW-SE trending‚ with some

Continental Drift and Plate Tectonics Theory (Part 1a) Introduction: The Beginning of the “Continental Drift Theory” In the middle of the eighteenth century‚ James Hutton proposed a theory‚ uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg‚ 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham

The Murray Darling Basin is a large geographical area that is of national significance both socially‚ culturally‚ economically and environmentally. It covers 1‚061‚469 square kilometers in area‚ which is about one-seventh of Australia’s total land mass and is home to over 2 million people. The Basin sits at the south-east corner of Australia and stretches across 4 states and 1 territory‚ passing through most

A plate tectonic is defined as a solid rock mass that builds up the Earth’s surface. The plate tectonic theory is a theory that geologists use to help explain the surface processes and events. The word plate means large pieces of the earth that are always in motion‚ lithosphere plates. Tectonics means how the continents formed and move over time. This is the theory that most geologists accept as to what happened to our continents. It states that Earth is made up of two layers‚ the lithosphere
