What are some geographic features of Venus?
Venus is extremely volcanic, having large smooth volcanic plains and several large "continent like" land masses that rise above the plain. The atmosphere is carbon dioxide with some nitrogen. Above the atmosphere are clouds of sulfur dioxide and sulfuric acid, leading to a pronounced greenhouse effect that has raised the average temperature to 460 C (860 F), hotter than Mercury.
Question was raised about the mass produced when a log burns The products have a greater mass than the original log that was burned Where did the extra mass come from?
A log mainly consists of carbon and hydrogen. It has a few other elements. Carbon has an atomic weight of 12. Hydrogen has an atomic weight of 1. Oxygen comes from the air. It has an atomic weight of 16. If you take one carbon atom from the log and you take 2 oxygen atoms from the air, you get carbon dioxide. Carbon dioxide will have a weight of 12 + 16 + 16 = 44. Water is two hydrogen atoms and one oxygen. Lets see 1 + 1 + 16 = 18. Now if we take a hydrocarbon with the equivalent of 12 water molecules attached to 12 carbon atoms the water molecules will cancel each other out. We only need to work with the carbon. We start with 144 as the weight of the carbon. When we add the weight of the oxygen from the air we end up with 528. That is what we get when we add oxygen from the atmosphere.
How do you calculate your carbon footprint?
A carbon footprint is a metaphorical representation of how much greenhouse gas a person produces in their life. This can include how much they recycle, or what type of light bulbs they use in their home.
How is haze related to global warming?
In 2007 the United States Supreme Court ruled that Carbon dioxide is a pollutant and so the EPA (Environmental Protection Agency) has the right to regulate CO2 emissions from new cars. Any burning of fossil fuels like gasoline releases long-hidden carbon dioxide, a powerful greenhouse gas. This extra gas is too much for the natural carbon cycle to remove from the atmosphere, so it remains there capturing the sun's heat and causing global warming.A:One definition of pollutant is "A substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource." Global warming, or climate change, is being caused by the enhanced greenhouse effect. This is caused by the extra carbon dioxide from the burning of fossil fuels (coal, oil and natural gas). It is also caused by methane belched from the many cows that are being raised just to feed red meat to the huge population of the world.These greenhouse gases are the pollution that is directly causing global warming.A:When pollution builds up in Earth's atmosphere, it can't escape. Heat from the sun shines through the pollution (greenhouse gases) and the greenhouse gases act almost like a greenhouse, trapping heat. So as more greenhouse gases build up, more heat is trapped in Earth's atmosphere, therefore causing Earth to heat up, and causing Global Warming. A:Pollution is the main cause of global warming. Pollutants such as greenhouse gases are often trapped in the atmosphere. As a result, heat is retained inside. This heat is what causes temperatures around the globe to rise thus causing global warming.Smoke from the factories and vehicles contain harmful chemicals which can also cause air pollution. Those air will gather to form clouds and later then will fall as a rain which is polluted and we call this as acid rain. Acid rain can damage the buildings and even can cause plants to die. Plants are the only living thing that can take in carbon dioxide and give out oxygen. if those plants will die, there will be to much co2 and lack of 02 in the air. That will be result in global warming.A:Air pollution occurs when any harmful gases and particles are sent into the atmosphere. Constant burning of fossil fuels is pumping large amounts of carbon dioxide and other gases into the atmosphere. The world's demand for red meat means that more and more cattle are produced, and methane gas from their ruminating is adding to the greenhouse gases.
What is the mass of one carbon atom?
the atomic mass carbon is 12.011 g/mol 12.011/mol = the mass of one atom 12.011/6.022x10 raised to the power of 23 this equals 1.994520093 x 10 raised to the power of -23 this is the mass of one atom of carbon in grams.
Do Oxygen and carbon dioxide contribute to air pollution?
No. Excessive release of carbon dioxide can contribute to acid rain, and it is believed to be a greenhouse gas, causing raised air temperatures.
If you have raised CO2 in the body does that mean your oxygen saturations would be lower and work of breathing would increase?
Oxygen is used to metabolize carbohydrates and produces carbon dioxide. In addition an increased rate of respiration will lower carbon dioxide levels while increasing oxygen concentrations to saturation. Despite this they are two independent parameters. If someone were to be at a high altitude they could have almost no C02 in their blood, be breathing rapidly and have low oxygen levels. Similarly carbon monoxide will bind strongly to hemoglobin so that oxygen levels will go down, but since except at very low levels of oxygen, breathing will remain unchanged as CO2 levels, which drive the rate of respiration normally will be unchanged.
What increases the amount of carbon dioxide in the atmosphere?
The burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide.DeforestationThe production of cement which contributes 5% of all man-made carbon dioxide emissions.A:Human activities are shown by atmospheric scientists to be responsible for increasing the amount of carbon dioxide CO2 in the atmosphere. The major sources of human emissions are the burning of fossil fuels such as coal, oil and natural gas for industry, driving our transport, heating our homes and generating electricity.Humans produce between 3 and 6% of all carbon dioxide emissions. Natural carbon sources produce much larger quantities than mankind, but this is offset by the vast natural carbon sinks that remove CO2 from the air. The current imbalance is due to human activity.We know where the increase comes from because CO2 from fossil fuels has a specific chemical signature, and scientists have observed that the proportion of CO2 from fossil fuels in the atmosphere has increased globally, and even more in cities and populated areas.Human emissions are not the only factor, but it is currently the most significant. For example, human emissions of CO2 are more than 130 times greater than the amount released by volcanic eruptions.More comments:Most of this increase in CO2 production (by man) is due to our ever increasing electricity consumption.Burning wood or allowing trees to rot does not increase the amount of carbon dioxide in the atmosphere, as long as old trees are replaced by new ones which absorb as much carbon as the old ones had done. This is essentially part of the natural cycle, in which carbon is continually added to and removed from the atmosphere But deforestation does increase the amount of carbon dioxide in the atmosphere, because new trees are not allowed to replace those removed.The most important way in which we add to the amount of carbon dioxide in the atmosphere is by burning fossil fuels. Another important contributor is the manufacture of cement. Climate scientists say that overall we have increased the concentration of carbon dioxide in the atmosphere by around 35 per cent since the beginning of the Industrial Age. The Carbon/CO2 on earth is part of a natural cycle which balances the CO2 in the atmosphere with the carbon locked in the rocks as limestone, and hydrocarbons. In general over the totality of geologic time the amount of CO2 in the atmosphere has fallen as a result of biological processes. In recent times human activity has been responsible for releasing a large quantity of fossil Carbon (oil, gas and coal) as CO2 into the atmosphere. While much of this has been buffered by the CO2 dissolving in the oceans, there has also been a marked increase in CO2 percentage in the atmosphere since the Industrial Revolution.The burning of fossil fuels is a primary source of increased atmospheric carbon dioxide. Motor vehicle exhaust and the burning of fuel oil in ships and factories or power plants puts lots of CO2 into the air. We also burn a lot of coal worldwide, and this also ups CO2 output by people. Additionally, the burning of wild lands (either by accident or on purpose) is increasing the amount of combustion byproducts (including CO2) in the air.Man uses energy. We create CO2 when we use energy. CO2 is the only gas in our environment that we make a substantial portion of. Man produces almost 7% of this gas. Much of this CO2 that we emit (over half) is to heat, cool and power our homes.Industrial activities have definitely contributed the most to the increasing levels of carbon dioxide in the air. Carbon dioxide is released when the factories are running and producing stuff. Burning of fossil fuels also cause it to rise.Every carbon-based life form (that includes every plant, animal, and human on earth) adds CO2 to the atmosphere when it decomposes (or is burned). As agriculture developed, bigger and better plants cover more of the earth and an ever-increasing number of livestock are being raised. In addition, carbon from coal petroleum deposits that have been buried for millennia are being extracted and burned, releasing even more CO2 into the air.Burning of fossil fuels and deforestation are the main causes of excess CO2... humans and other animals also increase carbon dioxide in the atmosphere since we breathe out CO2. Although, humans and other animals breathing is not the main cause of excess CO2 in the atmosphere.
How have green plants and other organisms changed the composition of the Earths atmosphere?
Hugely. Before the evolution of the first organisms capable of photosynthesis around 3 billion years ago, the atmosphere of the early earth contained almost no Oxygen. By the conversion of Carbon Dioxide and Water into organic compounds and Oxygen through photosynthesis, cyanobacteria, and later algae and plants, have raised Oxygen levels to around 21% of the atmosphere today. Without this high level of Oxygen, the huge diversity of multi-cellular life depending on Oxygen for aerobic respiration would not exist.

Venus is extremely volcanic, having large smooth volcanic plains and several large "continent like" land masses that rise above the plain. The atmosphere is carbon dioxide with some nitrogen. Above the atmosphere are clouds of sulfur dioxide and sulfuric acid, leading to a pronounced greenhouse effect that has raised the average temperature to 460 C (860 F), hotter than Mercury.
How does carbon dioxide water vapor and ozone get into the atmosphere?
The water/hydrologic cycle describes the flow of water on the earth surface, atmosphere and ocean. Water vapor in the atmosphere is formed via evapotranspiration. Plants release water via transpiration, and water evaporates from the soil.
Would a carbon tax reduce the amount of carbon dioxide entering the atmosphere?
Yes. A carbon tax is paid by polluters, such as owners of fossil fuel power stations. The more carbon they emit, the more tax they pay. They don't like paying tax, so they will make efforts to reduce their emissions. The tax raised can be used to encourage renewable energy projects which will reduce the demand for fossil fueled energy, putting more pressure on the polluters to do better.
Why isnt Mercury the hottest planet in the solar system?
In a nutshell, global warming gone mad. Although Mercury is closest to the sun it doesn't have an atmosphere to keep in the heat and has a temperature variation of -170 to +420 degrees. Venus on the other hand has a very dense atmosphere consisting mostly of carbon dioxide, which has trapped the heat in. This has raised the temperature on the surface of Venus to over +460 degrees.
What are some long term effects of global warming?
Long term effects of global warming are:It leads to increase in temperature which further leads to melting of glaciers into water which causes floods.Due to global warming percentage of carbon dioxide is raised and percentage of oxygen goes downin the future, more hurricanes will be category 5 or above!droughts will often occurdiseases will be uncontrollablealso if the levels of carbon dioxide in the atmosphere increase then the heat from the sun gets trapped and water from rivers and the sea will evaporate so there would be lots of water shortages and more rain storms.HOPE THIS HELPS!!
What atmosphere was Hypatia was raised in?
In an atmosphere which emphasized philosophy & science.
In what planet The temperature of its atmosphere is increased by the greenhouse effect.?
Burning fossil fuels (coal, oil and natural gas). This releases carbon that had been buried safely underground for 300 million years.Deforestation. Cutting down trees which used to take carbon dioxide out of the atmosphere.Another answerWarming temperatures have long been known to be the cause of CO2 increases in the atmosphere. We know that this is due to the number one absorber of CO2 from our atmosphere (the oceans) being unable to absorb CO2 as well as the oceans warm. Typically CO2 levels always follow temperature by about 800 years.
