Endogenous Theories For the Origin of Earth’s Water (Dry/Wet Accretion?)
Earth scienceAsked by: Alexandergraham Davis What is the origin of water on Earth? At present, asteroids up to a few hundred kilometers across seem the most likely sources of most of Earth’s water, specifically the types of asteroid that dominate the outer asteroid belt between Mars and Jupiter. What does it mean for the origins of

Could this cloud be artificially formed?
Earth scienceAsked by: Alexandergraham Davis Can you make an artificial cloud? Quote from video: Well it becomes a cloud as that water vapor rises in the atmosphere. It cools. And when it gets high enough it creates condensation it sticks to tiny particles in the atmosphere. How artificial clouds are formed? An artificial cloud in the

Why does Japan get so much snow?
Earth scienceAsked by: Melisa Peterson Japan’s sea-effect snow The combination of cold air, moisture from the Sea of Japan, and the lift created when the wind hits Japan’s mountains is what creates heavy snow,” says Gratz. Another factor that contributes to the consistent snowfall in Japan is that the water in the Sea of Japan does

Guidelines for locations of NTU markings on a turbidity tube
Earth scienceAsked by: Melisa Peterson How to measure turbidity with a turbidity tube? Quote from video: Look down through the opening of the tube. And look for the black and white pattern. If you can see this when the tube is full record 120 centimeters on your data sheet. How do you make a turbidity tube?

How long to melt all the polar ice?
Earth scienceAsked by: Lisa Carney There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit

Why isn’t Dorian raining on the southeast side?
Earth scienceAsked by: Lisa Carney Where is Hurricane Dorian headed? He is heading for an opium den, where old sins are forgotten and new ones found. Dorian craves opium. He feels afraid, and he is certain that there is no way to atone for his sins. The best he can hope for is to forget. Is

Measurement of groundwater levels
Earth scienceAsked by: Cindy Rogers Groundwater level measurement is mostly performed by a submersible pressure transmitter. These hydrostatic level transmitters are small in diameter and directly suspended by their cable into the well, borehole, deep bore well or monitoring well. How is water level measured? Air lines measure water levels by first measuring the pressure of

Using salinity to predict rainfall
Earth scienceAsked by: Cindy Rogers How does rainfall affect salinity? Where more rain or snow falls over the ocean, it dilutes the salts in the seawater there. As a result, the water becomes fresher with time. If seawater becomes saltier, it may mean that rates of evaporation have increased or that precipitation has decreased over time.

Could glacial melt alter plate tectonic movement?
Earth scienceAsked by: Katelyn Roy Are glaciers related to plate tectonics? According to new research, the transition to plate tectonics started with the help of lubricating sediments, scraped by glaciers from the slopes of Earth’s first continents. Can melting glaciers cause earthquakes? Scientists have known for decades that melting glaciers have caused earthquakes in otherwise tectonically

Where can I find a data set containing wetland loss by decade
Earth scienceAsked by: Jim Greenwood What percentage of all wetlands has been lost? It has been frequently stated, but without provision of supporting evidence, that the world has lost 50% of its wetlands (or 50% since 1900 AD). How much wetland has been lost in the US? It is esti- mated that, on average, over 60
