Your Name: Professor’s Name: Course Number: Date of Submission: Deep Ocean Mining Part 2 Deep ocean mining is an alternative to land mining in search of minerals such as copper‚ gold‚ manganese or cobalt among other minerals. The minerals on land are being depleted owing to the increasing demand for these minerals‚ and this makes the deep sea bed an alternative to the exploitation of minerals. The fact that the water

Assignment on “Brief History of Earth” Course: ENV 107 1 Brief History of Earth The history of the Earth concerns the development of the planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of the Earth ’s past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. Earth formed around

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms

On the Digermulen Peninsula‚ the succession starts with the classic Neoproterozoic glacial tillite of the Mortensnes Formation (Fig. 3). This tillite has traditionally been tentatively correlated by many workers (e.g.‚ Rice et al. 2011‚ and references therein) with the type ’Gaskiers’ glaciogenic succession in Newfoundland‚ which is between 584 and 582 Ma old‚ based on zircon U–Pb ages from intercalated ash beds (Bowring et al. 2002). The Mortensnes Formation is separated downwards from the ’Marinoan’

As geologists‚ we examine layers of sediment on the Earth’s surface to approximate the dates of past geologic time periods. Ah sediment as you know is material like sand‚ gravel‚ fossil fragments that is transported by natural processes like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For

1) Would earthquakes of similar magnitudes in different populated regions of the Earth cause approximately the same levels of damage? In your discussions‚ consider both geologic and human-induced factors. The amount of damage caused by an Earthquake does not solely depend on the magnitude of the Earthquake. Factors such as population‚ geographic location‚ soil type‚ and the type of building material commonly used for construction in a region determine the extent of damage caused. If an Earthquake

Space Exploration What is it and why is it important? Space exploration is scientific studies using scientific equipment in space and anything about it. There are different reasons why space exploration is important. We could discover new resources from other planets or the moon‚ other planets can be could be used when something happens to the earth and we need another place to stay on. Occupation Space exploration is a well-paid job because it could be very dangerous. You also

Two general processes used to figure out the age of rocks is relative dating and radiometric dating. We will compare and contrast the strengths and weaknesses of both methods. According to Lutgens and Tarbuck‚ Relative dating is the process in putting events in their proper sequence. Relative dating is based on assumption‚ not able to give an accurate date but an estimated time period where the rock originated from. A Danish scientist‚ Nicolaus Steno is accredited for the Law of Superposition.

Absolute dating methods are used to determine the age of materials. We need to understand how fossils are made so we can date them properly. There are five ways bones are fossilized. They are by permineralization‚ unaltered preservation‚ carbonization‚ authigenic preservation‚ and recrystalization (Shepherd). When a fossil is found you need to make sure that it can be preserved properly so it can stay in the same shape to enable research. Many steps are taken to prepare fossils and conserve them

Where exactly is Oklahoma? When geographers speak of location‚ they are using two separate definitions‚ each with its own useful purpose. The first of these is Absolute Location. Absolute location refers to an exact‚ pinpointed location. Absolute locations involve some sort of measurement‚ whether it’s latitude and longitude‚ an address‚ the number of miles from an exact point‚ etc. Pinpointing Oklahoma on a map using absolute location involves locating latitude and longitude lines on the map.
