Volcano Probe - Essay Example

Comments (0) Cite this document
A volcano can be said to be a geological landform where magma or molten lock in the earth's interior erupts through the surface of the earth. Melting of this lock is usually because of high temperature and pressure found in the outer core of the earth. Designing of a volcano probe therefore would require one to have a clear understanding of the earth interior starting from the crust, the outer mantle, the inner mantle all the way to the inner core…

It is pressure and temperature that explains how a volcano is formed and how it erupts on to the earth surface in the long run (Beatty, 1998, p. 67).
In general volcanoes normally occur in areas where tectonic plates diverge or converge or where the earth crust stretch or thin as in the case of African Rift Valley. Similarly, volcanoes can arise as a result of mantle plumes or hotspots which may occur far from the platonic plate's boundaries. Where volcanoes occur due to divergence of platonic plates, new oceanic crust is formed by hot molten lock or the magma which slowly cool and solidify. In essence, the crust is very thin at these ridges as a result of tectonic plates pull. Pressure resulting from the crust thinning gives rise to adiabatic expansion with a new oceanic crust forming as a result of partial melting of the mantle. In regard to converging platonic plates, the collision of a continental plate and an oceanic plate results into a subduction zone which by extension results into the submersion of the oceanic plate under the continental plate. The subducting layer releases water which lowers the temperature of the mantle wedge above the result of which is magma creation.
On the other hand, hotspots which are commonly located above mantle plumes where there is convection of the mantle of the earth results into a column of hot material that rises up to the earth crust. Plume temperature causes the crust to melt forming pipes useful in venting magma (Beatty, 1998, p. 98).
Following the above discussion, designing a volcano probe would require one to properly analyse the factors and forces behind volcano formation. In essence, one would be required to put into consideration the thermal forces involved and it is at this point that knowledge of thermal physics becomes essential. In this case, one would be required to design a temperature and pressure measuring system that is compatible with changes in the two parameters and which can withstand huge changes for that matter. As such, one would be required to consider the materials with which the pressure and temperature measuring system is built from as some materials may not be able to withstand huge changes in these two parameters. For example, metals are known to melt under different temperatures with some melting at lower temperatures than the others. Still, some of these metals when exposed to high pressures react or behave differently from the others (A.I.P. 2000, p. 56).
Any component designed to study the behavior of a volcano will have to put into consideration all the thermal physics aspects of pressure and temperature among other things. Such things include the permissible pressure range of the pressure sensor and the temperature range of the temperature sensor to be used in the measuring instrument. Equally important is the pressure and temperature range of the outer structure inhibiting the sensors. Moreover, the data collected by these sensors will need to be transmitted to a receiver through a transmitter. ...Download file to see next pagesRead More

Saturn's Moon Titan
The knowledge we have of Titan has been an evolution of learning that began with earth based observations and theoretical explanations. However, all that would change with the launching of the Cassini spacecraft and the Huygens space probe. The Huygens probe has been able to penetrate the atmosphere of Titan, land, and survey the surface of Saturn's most important moon.

The Magellan Mission was a follow - up mission of the previous Pioneer Venus Mission which mapped only 25 percent of the Venusian Surface near the north pole of the planet. The Magellan Mission's primary objectives were to map at least seventy percent of the surface at a resolution better than 300 m and to determine the global relief at a horizontal resolution of about 10 km and vertical accuracy of 80 km or better (Ford 1).
