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

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,

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

Is there any consensus of what caused the Lusi Mud Volcano eruptions in Indonesia?
Earth scienceAsked by: Catfish Rogers What caused the Sidoarjo mud volcano? It is the biggest mud volcano in the world; responsibility for it was credited to the blowout of a natural gas well drilled by PT Lapindo Brantas, although company officials contend it was caused by a very distant earthquake that occurred in a different province.

What is the highest balloons possible in a chain?
Earth scienceAsked by: Catfish Rogers How high can the highest balloon go? Typically though many balloons can reach between 90,000 feet (27,432 meters) and 125,000 feet (38,100 meters). Many balloons have gone above 130,000 feet, however around 130,000 to 137,000 is usually the theoretical maximum for most latex based balloons. In 2002, a balloon named BU60-1

What causes intra-plate faults, such as the New Madrid fault?
Earth scienceAsked by: Benito Hollo What causes the New Madrid Fault? The Reelfoot rift is identified today as a subsurface system of fractures and faults in the earth’s crust. New Madrid seismicity is spatially associated with the Reelfoot rift and may be produced by movement on old faults in response to compressive stress related to plate

Are the water year/hydrological year different around the world?
Earth scienceAsked by: Stacey Larson Why is a water year different? Its beginning differs from the calendar year because part of the precipitation that falls in late autumn and winter accumulates as snow and does not drain until the following spring or summer’s snowmelt. How is hydrological year determined? The water year is designated by the
