Asked by Laugh A - Thu May 22 23:43:06 2008 - - 3 Answers - 0 Comments

A. the nature of the magma (viscosity and gas contents) defines its nature of eruption. low viscosity and low gas contents will result in a lava flow. high viscosity and high gas contents will result in explosions.

The catastrophes of earthquakes and volcanoes are devastating to humans?
Q. yet they indicate a living and dynamic planet. How does plate tectonics help us predict where and when earthquakes will occur? Can we limit the devastation of earthquakes and volcanoes by knowing more about plate tectonics? Why does a seismic knowledge of the interior of the Earth help us on the surface? Should we initiate planning to avoid catastrophe-prone areas, or should we try to protect against those catastrophes as they occur?
Asked by Wiifey2Boyd650 - Fri Mar 28 16:11:25 2008 - - 2 Answers - 0 Comments

A. 1) Earthquakes are extremely common at plate boundaries. Knowing where these boundaries are gives us a better idea as to where to expect EQs 2) Yes and no. The more we know about plate tectonics the more we can learn about EQs. But EQs, though statistical in some ways, are still hard to predict. 3) Knowing the interior of the Earth helps us know how soon waves are going to end up in other places. 4) What hasn't been planned, plan and build away from prone areas. What has been planned and built needs protection and better warning systems.

How does geothermal energy from volcanoes work?

Asked by wild child - Tue Nov 3 12:45:50 2009 - - 3 Answers - 0 Comments

A. Geothermal Energy is essentially the heat that comes from within the Earth. The word 'geothermal' itself is derived from two Greek words. 'Geo' implies earth. 'Therme' implies heat. The hot water and steam produced withinthe Earth can be harnessed for electricity generation and heating of buildings. Geothermal Energy generated by the Earth's interior is renewable energy. Geothermal reservoirs are mostly situated deep inside the Earth. Geothermal energy sometimes finds a way out in the following forms. # Volcanoes # Geysers. # Fumaroles (holes which release volcanic gases) # Hot springs The majority of the active geothermal resources can be found along the main plate boundaries. These areas are marked by heightened volcanic activities… [cont.]

A. I'd like to know where you got your information. Are you taking erosion into account? The Big Island of Hawaii, for example, is approximately 1 million years old. It's huge - scientists now think its total height from base to summit is a stupendous 17,000 metres! 11,000 metres from sea floor to summit, but because it has sunk into the earth's crust due to its sheer size and weight, they estimate it's another 6000 metres on top of this. Absolutely amazing. Now, consider that Hawaii is part of a huge chain of volcanoes, stretching northwest to past Midway Island, then due north almost to the Aleutians. Each volcano is progressively older as we head northwest/north. Erosion from the sun, wind and rain, and then the sea itself when the… [cont.]

Asked by Alyss Heart - Wed Nov 7 21:18:15 2007 - - 3 Answers - 0 Comments

A. The differences between a cinder cone and shield---a cinder cone's angle of repose is about 30 degrees, where a shield is around 15 degrees. It's been a while but i think the magma in a cinder cone is less viscous than a shield. A composite is a little wierd. The viscosity of the magma determines how explosive a volcano will be, the less viscous the more explosive. A composite volcano can move on that scale, in one eruption it may pour magma that is like a river, then in another eruption it may explode like an a-bomb. Cinder volcanoes and composite can be explosive whereas shields are usually not. Hope this helps some.

Asked by skierlara - Wed Apr 15 14:47:45 2009 - - 2 Answers - 0 Comments

A. Actually, most planetary scientists do not think there was ever plate tectonics on Mars, or on Jupiter's moon Io, which is the more volcanically active thing in the Solar System. You can get volcanoes, like hot spot volcanoes here on Earth, popping up between plates, just from strong convection in a very hot mantle. You can get volcanoes popping up from deep meteorite impacts that penetrate into a molten mantle. Or, like on Jupiter's moon Io, you can get extreme gravitational pulling and shearing from a nearby huge planet, which heats the mantle and causes the crust to crack and volcanoes form there.

A. The Hawaiian islands are hot-spot islands which form as an oceanic plate moves across a fixed mantle hot-spot. The volcanic islands form as the plate moves over the hot spot, and as it moves away the volcanoes die and become extinct, and a new volcanic island emerges, so the answer is B. Read up on hot spots:

A. There are two types of volcanoes, they are andesitic and shield. Andesitic are found along plate subduction zones while shield volcanoes produce islands from oceanic hot spots. Andesitic volcanoes are highly viscous plagioclase and feldspar and form from more explosive events, while shield volcano have low viscosity and flow smoothly without explosive events. Volcanoes are built up from hot, molten lava flowing through vents from the earth's mantle.

A. The mantle, which is a flexible part of the earths inside, moves because of unequal distributions of heat. the moving mantle causes the crust/tectonic plates to move. if they are pushed together, then that is convergent. this can form volcanos. i just learned this in school!

Asked by Miss Lal - Sat Nov 15 20:39:37 2008 - - 4 Answers - 0 Comments

A. The movement of tectonic plates results in their inevitable convergence in some places. The types of convergence include consuming, where one plate passes under another (subduction), collisional, where both crumple and maintain pressure against each other, and transform, where the plate margins slip against one another. Consuming plate margins, where one plate is subducted beneath the other, results in melting of some of the subducted plate at depth. Some of that magma rises to the surface of the other plate, forming volcanoes. The ongoing collison of the plates produces earthquakes, particularly when the motion between the plates is temporarily stopped by one plate becoming jammed. Whenm motion begins, it is usually associated with a… [cont.]

A. Active volcanoes are ones that erupt regularly. Mt. Erebus IS erupting (continuously since the 1970s), and has been off and on since it was discovered. Of the four volcanoes on Ross Island, it is the only active one. The other three are Mt. Terror (both Erebus and Terror are named for Sir James Ross' ships), Mt. Terra Nova (named for R.F. Scott's ship), and Mt. Bird (named by Scott's men for Cape Bird). Mt. Discovery (named for one of R.F. Scott's ships as well) is also a volcano that lies at the head of McMurdo Sound. R.F.

A. Yes, it is more or less very safe. The volcanoes in Hawai'i are all shield volcanoes, so lava merely flows, they never erupt explosively. You are perfectly safe form volcanoes. Recently, however, Kilauea has been emitting massive amounts of smoke into the air, so bad that people in Kona cannot see the top of Mauna Loa and have had to drive with headlights on in the past. But, since Hilo is in the rainforest, the rain will wash away the smoke and you'll never even know Kilauea is emitting smoke. Therefore, you are perfectly safe from volcanoes of any kind. Tsunamis are your only other threat. It takes a few hours for a tsunami to cross the Pacific, and Hawai'i has the most advanced tsunami detection system in the world, so you will have… [cont.]
