How does sea floor spreading alter the shape of the ocean floor?
Hi. As the spreading allow lava out it will create undersea mountains and ridges.
Does sea floor spreading create or destroy new oceanic crust at mid ocean ridge?
Creates
Why did the dry ice smoke falls to the floor and flow downwards?
Dry ice, carbon dioxide, is more dense than air.
What process would bacteria living near a heat vent on the ocean floor use to build carbon- based molecules such as sugars?
The answer to this question is..... Your mum.
What are the carbon emissions created by nuclear power stations?
Nuclear energy has a significant carbon cost of mining uranium fuel. This carbon cost is usually exported to another nation's mines. The actual carbon cost can be reduced by cutting safety in extremely poor countries, which leads to greater worker mortality but doesn't show up in the carbon budget.The best nuclear ores are all mined. The true carbon cost of additional nuclear energy must be measured in the carbon cost of mining additional ores, not in the current average carbon cost of mining.The carbon cost of the threat of terrorism incidents at nuclear plants is hard to calculate. Are we invading other countries because terrorist organizations will strike domestic nuclear power plants first? Also, would one successful terrorist incident instantly double the carbon cost of protecting all nuclear power plants?We don't know how to measure the carbon cost of protecting people from nuclear waste for thousands of years. For example, the current U.S. policy on nuclear waste at the Hanford Military Reservation, which is in the floodplain of the Columbia River, is to leave the waste in place underground until it leaks into the river and is gone, or until a river flood overruns the area. This method of neglect produces a very small carbon footprint.The decommissioning of reactors has a high carbon footprint. The carbon cost of decommissioning can be amortized over more years of electricity production by extending a nuclear plant's lifetime. However, old nuclear plants tend to have more radioactive leaks, and may have a slightly higher risk of a disaster.The Ukraine has an issue where authorities have encased the disastrous Chernobyl reactor in a concrete casing and have abandoned the nearby city and region. Nuclear radiation has helped destroy the casing, and a new concrete tomb is planned. The entire region of Chernobyl is now threatened by fuel buildup on the forest floor. A forest fire would pump huge amounts of radiation into the air, which would cross national boundaries. Again, this storage problem's carbon footprint is low, simply because in case of a fire much of the isotope radiation would blow into some other country.What we find is that the carbon footprint involved in generating nuclear energy and nuclear safety efforts are inextricably linked. The carbon costs in keeping people extremely safe from radiation would be enormous. Nuclear energy would be a net carbon sinkhole, where it would be more practical just to burn fossil fuels for electricity. If, however, many public health and safety shortcuts are taken by a government, especially by exporting safety problems or ignoring the mining and nuclear waste problems, nuclear energy has a much lower carbon footprint than just burning fossil fuels.A:Early studies of the carbon footprint of nuclear power seem not to have included the construction, decommissioning, and waste disposal, which are always included in a total carbon footprint. Waste disposal is a particularly difficult area to deal with because no one know how it will be done, so no one knows what figures to use for carbon footprints. So estimates from studies dated 1998 to 2003 at the carbon footprint were all in the range of 11-13 grams of CO2 equivalent per kilowatt hour (g. CO2e/kWh). Four studies in 2004 and 2005, two of which agreed with the earlier estimates, produced an average figure of 43.5 CO2e/kWh. Five studies in 2006 produced an average of 84 CO2e/kWh. And three studies in 2007 produced an average of 93 g. CO2e/kWh for nuclear power. Since the earlier studies were clearly not addressing the total carbon footprint, and the later ones were, we can probably use a figure of 85 g. CO2e/kWh. An article by Benjamin Sovacool arrives at 65 g. CO2e/kWh, averaging the early and late numbers, but the earlier numbers are clearly wrong, despite the fact that they are much quoted. To put this into context, the following are average estimates of total greenhouse gasses by production type with numbers of grams of CO2e/kWh:1000 - coal900 - oil750 - open cycle natural gas580 - closed cycle natural gas(closed cycle natural gas combined with co-generation might bring this down to 400 g. CO2e/kWh)500 coal plant burning 50% coal with 50% miscanthus110 - old solar photovoltaics95 - biomass from miscanthus85 - nuclear40 - concentrated solar thermal with thermal storage35 - new solar photovoltaics25 - biomass from gasification of wood chips (used to fuel conventional natural gas turbines)21 - wind15 - hydroelectricity
How do you remove footprint mark on stone floor?
lick the floor until it is clean. or pee on it and rub it off
What do you call it when someone dropped rubish on the floor?
That person is a litter-lout, who is littering by dropping rubbish on the floor.
What is the purpose of building a skyscraper?
Skyscrapers maximize the building footprint on the ground, by providing additional square footage for each floor above the first that essentially duplicates the building's footprint.
what are the floor dimensions of this bike?
If you mean footprint then 50 by 22.5 inches (L x W)
Why are waiters rude?
maybe cauz they had enough of costumers ,leaving rubbish on the floor and shouting to much...
What are the rules for safe handling of rubbish?
The rules of 'safe handling rubbish' can be 1. Never throw your litter on the floor. 2. throwing litter attracts many rats...... and so on.
A Floor Of Or Near A Fireplace?
The hearth (pronounced harth). This is also refered to as a firebox floor. If there is a grate on the floor of the firepalce it is called an ash grate which leads to an ash pit.
When you throw the rubbish on the floor then what happen?
wind or rain carries it down a drain or up into the sky where it then travels. if it is rain, and it goes down a drain, all drains lead to the ocean so where do you think the rubbish will go?
What do you use to get carl's footprint in mysims agents on Wii?
To get Carl's footprint, go into the Kitchen, take out your F-Space Manipulator and smash the jelly jar on the table in the middle of the kitchen. Go talk to Carl. Ask Carl to make you something to eat. Carl will go and make you a sandwich and step in the jelly on the kitchen floor, leaving a footprint.
What does restaurant crew member mean?
Their duties are to do food preparation and to go around and clean up any rubbish on tables and floor.
Where is a carbon dioxide monitor to be mounted top of wall or next to floor?
Carbon Dioxide is heavier than air so the monitor will work best near the floor. However is your monitor for Carbon Dioxide or Carbon Monoxide. If the latter, CO detectors can be placed near the ceiling or near the floor because CO is very close to the same density as air.
Why is the portable trash can convenient?
A portable trash can (rubbish bin) is useful to us humans in many different ways, these include: You don't have to find a bin They are easy to use And can be used for cleaning if you were to move it around and pick up rubbish on the floor.
