Cloud in a bottle experiment. Why does the “cloud” get thicker with repeated squeezing?
Earth ScienceAsked by: Heather Morris What happens to the cloud as you squeeze the bottle? When we squeezed the bottle, the cloud disappeared because of high pressure and compressional warming with the molecules close together in the bottle. The smoke from the match we dropped in was crucial because it provided condensation nuclei on which the

Effects of currents on peak wave frequency
Earth ScienceAsked by: Stacy Bergmann Do currents affect waves? As the surface currents affect the spectral wave energy, the bottom friction will also experience change. Bottom friction will increase with increasing wave energy e.g. in the case of an opposite current. What affects ocean wave frequency? The frequency of ocean waves depends on the wind speed,

Can someone help me identify this cloud formation?
Earth ScienceAsked by: Stacy Bergmann How do you identify cloud formations? How to Identify Cloud Types Stratus clouds are uniform grayish clouds that often cover the sky. Usually no precipitation falls from stratus clouds, but they may drizzle. … Cirrus clouds are thin, wispy clouds blown by high winds into long streamers. … Cumulus clouds are

How does the existence of a Greenhouse Gas Effect (GHE) in the atmosphere affect the tropospheric lapse rate?
Earth ScienceAsked by: Nicole Phillips How does the atmospheric lapse rate affect greenhouse warming? A stronger lapse rate (the rate of decrease of temperature with altitude) gives rise to a stronger greenhouse effect and a warmer surface, all else being equal. If the lapse rate changes systematically with the surface temperature, then a potentially strong lapse

Why does volcanic dust pose such a hazard to air travel?
Earth ScienceAsked by: Nicole Phillips How do volcanic eruptions affect air travel? Volcanic eruptions and air travel Airplanes can’t fly through volcanic ash. Ash particles can seize engines, and reduce visibility to dangerous levels. If a volcano erupts, or is expected to erupt, airlines will avoid the area. What are the flight hazards caused by volcanic
