native only to itself. The purpose of this essay is to discuss the geological history of the formation‚ as well as the biological origins‚ of New Zealand. It will also discuss how the major land-forming processes of volcanism‚ glaciation and tectonic plates have shaped the country and defined it’s native flora and fauna. Eighty-five million years ago the landmass now known as New Zealand broke away from the supercontinent Gondwana. This massive landmass moved into the Pacific Ocean and eventually

Volcanoes and Earthquakes test Bew c. 1. Where do earthquakes occur? Earthquakes occur at breaks in the earth’s crust called the fault lines. 2. What causes Earthquakes? Tectonic plates pushing‚ pulling‚ slipping past each other increasing the stress and causes elastic rebound to happen. During elastic rebound‚ energy is released and some travel as seismic waves‚ which cause an earthquake. 3. How do earthquake waves travel and what are the various types of waves? Body waves

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

Vinoth Loganathan New Zealand is a country which ‘straddles’ between two tectonic plates; the indo-Australian and the Pacific. The location of the South Island is south of both Australia and South Africa; this is a major contributor to the geological process of weathering because it makes Mt. Cook subject to the westerly winds. MT Cook is situated in the Southern Alps between the two tectonic plates mentioned above. Its current height is now stated at 3‚753 meters making it the tallest

The Earth is always forming and releasing pressure in different ways. Sometimes the Earth’s mantle builds up so much pressure that it starts to shift tectonic plates‚ and due to this we can see changes on our surface as well. We experience big changes like volcanoes‚ earthquakes‚ trembles‚ and continental drift‚ but a few minor things happen as well. Some of these minor results can include geysers and fumaroles. A fumarole is a very important formation that is needed to release pressure from deep

de Fuca Plates. The oldest crust is along the Japan Trench and Marianas Trench. This is the outermost layer of the Earth. 6) Now look the Atlantic Ocean Basin‚ and compare the pattern of older/ youngest oceanic crust to what you say in the Pacific Ocean Basin. Are these ocean basins alike or different; could they be both? The Atlantic Ocean Basin is quite different from the Pacific. The Atlantic Basin has more activity vs the Pacific by way of plate tectonics. There are more plate boundaries in

the surface of the Earth. Continental drift: Movement of the Earth’s continents comparative to each other by appearing to drift across the ocean bed. Tectonic Plate: Large pieces of the Earth’s crust that float on the mantle. These plates are constantly moving and may crash into each other or slide or move apart from each other. Continental Plate: Large sections of the surface of the Earth that move separately. Shield Volcano: Volcanoes formed by viscous lava and have broad and flat sides. This

pieces of evidence towards proving that the plate tectonics theory is valid” Discuss the extent to which you agree with this statement (40m) The theory of plate tectonics explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which the plates converge‚ diverge or move past each other. These plates are either continental or oceanic and are

Evidence for plate tectonics (http://www.bbc.co.uk/schools/gcsebitesize/science/aqa/oils/changesrev3.shtml) b About fifty years ago‚ new evidence convinced scientists that the Earth’s crust is made up of tectonic plates that are moving very slowly. Give two pieces of evidence that have helped to convince these scientists that the tectonic plates are moving. The movement and separation of continents and Earthquakes are a result of plate movement. They are the sudden
