Assignment 2 1. At first glance, the Moon and Mercury have similar surface features yet on closer inspection we find that significant differences exist. Compare and contrast the surfaces of the two bodies and outline their respective geological histories. The geology of the moon and mercury are very similar due to certain key aspects, but there are also a few qualities that differentiate the two bodies. The Moon has a radius of 1738km in comparison with Mercury, the smallest of the major planets with
abandoned place and would contaminate aquifers through their recharge zone. It is important to first solve the use and dispose of chemical elements exposed in a mine before abandoning it. Ore deposits Very often, the presence of certain elements, such as mercury, arsenic or radioactive elements, are concentrated in an area close to the aquifers and represent a hazard. When drilling claystone is easy to find high emissions of radiation and it is possible to read it through electrical registers inside the well
Mercury: The element mercury has the chemical symbol Hg; it is a silver colour and is a liquid at room temperature. Mercury has a high density and surface tension and can easily break up into small droplets. Mercury can dissolve some metals resulting in amalgams, metal alloys of mercury. It is not soluble in water or most other liquids, but will dissolve in lipids (fats and oils). With fluctuations in temperature, mercury expands and contracts evenly with these changes and is classed as a non-combustible
Plate tectonics occur not only just on Earth, but on other planets in the galaxy as well, such as Venus, Mars, and ancient Mercury. Since there are several planets in the Milky Way that have plate tectonics, it is questionable about if size is a key factor in the likelihood of tectonics on foreign planets. Vol-canoes, mountains, ocean ridges, earthquakes, and tsunamis all would not be possible without the movement of the Earth’s tectonic plates. Dependent upon heat for movement, tectonic plates are
of the Earth. This material then underwent the process of accretion and formed what we now know as the moon. With modern laser altimetry, scientists have been able to accurately measure the topography of the moon. The most apparent topographic feature on the moon is located on the southern pole, is referred to as the Aitken basin, and stretches nearly 1400 miles in diameter. This is the largest crater on the moon and the largest known crater in the Solar System. Not only is this the widest crater
through the middle, which is dominated by the Volcanic Plateau which is an active volcano and one of the main thermal areas in new Zealand New Zealand is on the constantly shifting plates, the Australian and pacific, and thats why there is a lot of geological action. Rotorua includes the biggest mud volcano in
The opening up of the north polar sea between 1815 and 1817 had prompted Barrow to propose a plan to send two expedition voyages, one in search of the Northwest Passage and the other to proceed from the sea of Spitzbergen towards the North Pole. Accordingly he sent the plan to the President and Council of the Royal Society which duly returned with their approval and the orders were issued by the Board of the Admiralty. Examining such interplay between scientific institutions, such as the Royal Society
Hence there is no rainfall as such. The winters are severe and the mercury dips down to more than minus 20 o Celsius.The summers are pleasant but the shady areas tend to be cold. During summers the cold winds blow down the valley, whipping up lots of dirt.The main cash crops of the area are seed- potatoes, Kuth, manu kuth

Kira Hallerbach Mr. Munson 5* Honors English 7 March 2016 Nuclear Power is the most Viable Replacement for Fossil Fuel The use of fossil fuels as a primary source of power is poisoning our world, and nuclear power is just the way to stop this. Nuclear power is using the process of nuclear fission to create electricity. Nuclear fission is the splitting of a uranium atom to release massive amounts of energy. When this process takes place in a nuclear reactor, the energy is used to superheat water which
