interior of the Earth holds a tremendous store of heat released primarily from the ongoing decay of radioactive elements. Earth’s internal energy flows unceasingly toward the surface. * Over short time span: released as eruptions from volcanoes and by earthquakes. * Over long intervals of geological time‚ the flow of internal energy has produced continents‚ oceans and atmosphere. * On a planetary scale‚ this outward flow of internal energy causes continents to drift

Remove crystals from an andesitic magma and you will get? -A more felsic residual melt 4. Which of the following types of volcanoes is typically the largest in terms of overall volume? -Shield Volcano 5. What minerals are involved in the continuous part of Bowen’s Reaction Series? -Plagioclase Feldspar 6. Which of the following minerals (as shown by their chemical formulae)

largest of the Hawaiian Island Shield volcanos. Because of this great size the volcano actually slumped 42‚650 feet below sea level‚ not only is Mauna Loa is the largest in the Hawaiian chain‚ it is also the largest on earth. Of all the Hawaiian volcanoes‚ Kilauea is the most active with its current eruption going on since 1983. Mauna Kea‚ though overall smaller than Mauna Loa‚ actually has a high elevation. Its smoother profile is due to it being estimated at over a million years

Diamonds are seen everywhere in stores and they are displayed in necklaces‚ earrings‚ pins and rings. They sparkle brilliantly in the right light. More than likely‚ most people don’t know how that diamond made it to the

arc-trench systems in the country: the Kuril Trench‚ Japan Trench‚ Izu-Bonin Trench‚ Ryuku Trench (partially pictured)‚ and Nankai Trough. Here‚ we can observe that the trenches (yellow line) are parallel to the volcanoes (red dots). You can almost draw a straight line to connect all the volcanoes. Moreover‚ the data above is evidence of the presence of subduction zones wherein the collision of two plate boundaries causes the denser plate to sink below the less dense plate into the asthenosphere. This
Premium Plate tectonics
Volcanoes are formed on land near coastal areas when a continental plate and an oceanic plate converge. The oceanic plate submerges‚ due to its higher density‚ and is pushed deeper and deeper beneath the surface. The high temperature and pressures below

Continental drift The broad shape of Australia and its distinctive landforms have been influenced over long periods by earth movements that cause the breaking and bending of the Earth’s crust. Geographers call these movements tectonic processes. The Earth’s crust is made up of many individual moving pieces called tectonic plates. There are nine large plates and about a dozen smaller ones. The larger plates contain the continents and oceans. These plates ‘float’ on the dense layer of rock below

other geological hazards at our peril. Discuss. (40marks) Geological hazards are events that are perceived as a threat to people‚ poverty and nature‚ which originate in‚ or transmitted by the physical‚ built or human environment. These can include volcanoes‚ hurricanes and earthquakes‚ which all have various effects ranging from affecting people to the natural and physical environment. Looking at earthquakes in particular‚ which are vibrations of the earth caused by rupture and sudden movement of rocks
