He suggested that at the centre of oceans, molten material would rise from the Earth’s mantle, causing new sea floor to be created, pushing the ocean floor. He also suggested that there were ocean trenches where old sea floor would then go back into the mantle, and molten. He found that these ocean trenches, the deepest parts of the ocean, were very near continental plates. Hess theorized that the action of the sea floor spreading caused continents to move apart and so this being evidence for continental drift, showing why it happened. The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor.
Bowman- These types of radios are the advancement of the future the Ministry of Defence use and will update. This type of radios replaces all types of ageing clansman radio such as the PRC-344 etc. Bowman radios are able to transmit electronic data extremely fast allowing real time updates in operations. This radio covers all very high frequencies and high frequencies but is is also secure. The bowman radio can be both man portable and vehicle based and can also operate out in the sea and in the air.
All of these solutions have many issues. Hydrogen needs more technology and about fifty years to become cheap and available. Bio-diesel would do more harm than good using food for fuel instead of for worldwide hunger. Solar and wind power would take a lot more development of gathering this natural resource and would take time. The only way to face this problem is head-on.
The company really needs a complete overhaul so that it can gain a sustainable, comparative advantage in the marine anchor market. Question 1 Based on the information presented in the scenario/case study discuss Albatross Anchor’s competitiveness in relation to (please address all items in the below list and provide support for your conclusions): 1. Cost a) Cost or Production: Operational inefficiencies have caused production costs at Albatross Anchors to be a lot more than they should be. This means they have a smaller profit margin, inefficiencies eating up their potential profits. They could be making more money per unit if they would tighten up their processes.
Wind turbines are clean, effective and nonpolluting; however, one cannot predict the speed or direction exactly. The heavier populated areas require more energy. Not enough wind and the turbine will not turn. Wind turbines are noisy, threatens wild life, and is an eye sore along with costly for the initial funding. Solar energy is a non-pollutant, cost effective, maintenance free, life span of up to 40 years; however the upfront cost is enormous, and not everyone can afford the cost to put the stylish panels on their roof tops.
Flat land over the levels meant water couldn’t be quickly taken away, meaning the depth of the flood increased largely. During high tides, sea water makes its way upstream meaning discharge in the rivers at this time is already high, without the excess rainfall. When storms hit during high tides, the river quickly reaches its capacity and floods excessively. When the
The principle of underwater welding procedure takes in the manner where the work to be welded is connected to one side of an electric circuit, and a metal electrode to the other side. These two parts of the circuit are brought together, and then
They were mostly limited to going backward and forward and they were not able to travel very fast or far at all. It wasn't until Portugal became a mighty sea power that the Maritime Revolution and change was able to occur. Portugal, having much contact with the Arabs who occasionally docked in the Portuguese ports, was able to convince them to reveal the technology of their ships which brought about great change to European ship designs. Caravel ships with lateen (triangular) sails were traded for the huge carrack ships. Caravel ships were much smaller, much lighter, and very faster than their counterparts.
Throughout the 45 days of school the expenses increase which makes a huge difference. It makes the Utility bill go a lot higher than the regular schooling. Air conditioners will have to be kept on in the summer to cool off the kids in the mild weather. Even the heater, we don’t want children’s to have frost bites. Staff members have to get paid too.
He said that the worldwide population will triple over the decades; so, nuclear energy would be essential for many lives that have come a costume and rely on this source of energy. He also points out the fact that nuclear power plants are essential because it is a powerful source of energy. It is relatively cheaper and faster compared to other alternative sources. Nader counters with the possible devastating outcomes that could be created by leaked radiation from damaged nuclear power plants would result in inhabitable lands. He also points out the fact that people should focus on the present consumption of energy, rather than the future for energy conservation.
