How to interpret the values of moisture flux convergence?
Earth ScienceAsked by: Danielle Smith What is moisture flux convergence? Moisture flux convergence (MFC) is a term in the conservation of water vapor equation and was first calculated in the 1950s and 1960s as a vertically integrated quantity to predict rainfall associated with synoptic-scale systems. What is moisture flux divergence? Its horizontal divergence is the rate

Is there any rule of thumb to decide the indentation hardness test?
Earth ScienceAsked by: Becky Rabe How do you calculate indent hardness? In microindentation testing, the hardness number is based on measurements made of the indent formed in the surface of the test specimen. The hardness number is based on the applied force divided by the surface area of the indent itself, giving hardness units in kgf/mm².

If Earth had rings would gravity exerted by Earth decrease?
Earth ScienceAsked by: Janet Dunn Rings wouldn’t decrease the gravity much, but the exact amount would depend on the exact geometry of the rings. One reason is that the gravity of one side of the ring would partially cancel the attraction of the other side. What would happen to Earth if it had rings? At the

Can airplanes trigger rain?
Earth ScienceAsked by: Janet Dunn Planes flying through clouds can increase rain or snowfall by as much as a factor of ten, scientists in Finland have discovered. This intensification of precipitation is not caused by emissions, say the researchers, but by ice crystals created as the aircraft’s wings pass though cloud layers above active rain or

Is Antarctic sea ice at record levels?
Earth ScienceAsked by: Thao Adams Sea ice around Antarctica has reached a record low in four decades of observations, a new analysis of satellite images shows. Is Antarctic sea ice increasing? From the start of satellite observations in , total Antarctic sea ice increased by about 1 percent per decade. Whether the increase was a sign
