LWC and Absolute Humidity
Earth ScienceAsked by: Ashley Benavides What is the difference between humidity and absolute humidity? Or to put it simply, relative humidity indicates the actual water content of air as a percentage of the maximum amount it could possibly hold. The term absolute humidity is less common: it describes the actual amount of water vapour in the
When is the next glaciation due?
Earth ScienceAsked by: Ashley Benavides Predicted changes in orbital forcing suggest that the next glacial period would begin at least 50,000 years from now. Moreover, anthropogenic forcing from increased greenhouse gases is estimated to potentially outweigh the orbital forcing of the Milankovitch cycles for hundreds of thousands of years. What is the next glacial period? Next
How is phosphorus getting into lakes and rivers?
Earth ScienceAsked by: Jenny Foster Because phosphorus usually clings to soil particles, the main way in which phosphorus gets into water is when soil is washed in and becomes sediment. Excess phosphorus causes excessive growth of plants in waterways, lakes and estuaries leading to eutrophication. How does phosphorus get into a river? Phosphorus moves through the
Would the Earth function the same spinning the other way?
Earth ScienceAsked by: Jenny Foster An Earth spinning in the opposite direction would have very different atmospheric and ocean currents. Although the global mean temperature would remain almost the same, the major ocean currents would switch from the Atlantic to the Pacific, changing the planet’s climate drastically. What will happen if the Earth starts rotating in
Would epicenters in less-deep areas of ocean tend to reduce the impact of a resulting tsunami somehow (wave “breaks” before getting there?)
Safety & HazardsDo Shallower Ocean Earthquakes Mean Smaller Tsunamis? Let’s Talk About It. Tsunamis. Just the word sends shivers down your spine, right? We all know how incredibly destructive they can be, but what actually makes one tsunami worse than another? A question that pops up a lot is this: does the depth of the ocean where
How would one get a submarine to rise?
Earth ScienceAsked by: Mike Burrell How do submarines rise to the surface? In order to control buoyancy, the submarine relies on special tanks that can be filled with water or air. To return to the surface, the tanks are filled with air. This makes the submarine less dense than the water around it, causing the sub
