What are the natural causes for methane formation?
Earth ScienceAsked by: Emma Jones Methane is produced by the breakdown or decay of organic material and can be introduced into the atmosphere by either natural processes – such as the decay of plant material in wetlands, the seepage of gas from underground deposits or the digestion of food by cattle – or human activities –
Could we plant enough trees to offset greenhouse gas emissions?
Earth ScienceAsked by: Emma Jones How many trees would it take to offset global warming? A single mature tree, meanwhile, may take in about 50 pounds of carbon dioxide per year. At this rate, it would take 640 trees per person to account for all American emissions, which adds up to more than 200 billion trees.
Is there a correlation between the underwater geological activity and topology of the mid Atlantic ridge/ South American plate and the Gulf Stream?
Earth ScienceAsked by: Lina Smith What is the Mid-Atlantic Ridge and how does it play a role in plate tectonics? In between these continents lies the Mid-Atlantic Ridge, a site where new plates are formed and a dividing line between plates moving to the west and those moving to the east; beneath this ridge, material rises
Does Earth risk losing its oceans to space due to global warming?
Earth ScienceAsked by: Lina Smith Does Earth lose water to space? Water, as a vapor in our atmosphere, could potentially escape into space from Earth. But the water doesn’t escape because certain regions of the atmosphere are extremely cold. Does global warming affect the ocean? Today, the ocean has absorbed about 90 percent of the heat

What is the basis for the Geologic Time Scale
Regional SpecificsAsked by: Carlos Weeks The geological time scale is based on the the geological rock record, which includes erosion, mountain building and other geological events. Over hundreds to thousands of millions of years, continents, oceans and mountain ranges have moved vast distances both vertically and horizontally. What is the basis of the geologic time scale
