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
Where does all the earth from surface mining go?
Earth scienceAsked by: Thao Adams How does surface mining affect the Earth? Surface mining (another name for “strip mining”) can severely erode the soil or reduce its fertility; pollute waters or drain underground water reserves; scar or altar the landscape; damage roads, homes, and other structures; and destroy wildlife. Where does surface mining happen? There are
Differentiate correlation of between depth and bouguer anomaly
Earth scienceAsked by: Melissa Craven What is the Bouguer gravity anomaly? [ bōō-zhâr′ ] The difference between the expected value of gravity at a given location (taking into account factors such as latitude, longitude, altitude, and the rotation of the Earth) and its actual value. How do positive and negative Bouguer anomalies differ? The Bouguer anomaly
What role does the hydrosphere play in tectonic plate convection?
Earth scienceAsked by: Melissa Craven Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries. What role does water play in plate tectonics? On the Earth, water plays a necessary role in shaping plate tectonic activity, as
Waves on sandy beach separating differently-sized rocks?
Earth scienceAsked by: Marshall Zellner Why does sediment size vary along a beach? The size of sand grains is related to the slope of the beach. For example, the steeper the beach, the larger the sand grain size tends to be. This is because larger particles can be cast higher up the beach by the waves
Can anyone explain this frost phenomenon?
Earth scienceAsked by: Marshall Zellner What is the causes of frost? Frost usually forms when a surface cools through loss of infrared radiation to a temperature which is colder than the dewpoint of the air next to the surface, AND the temperature of that surface is below freezing (32 deg F, or 0 deg. C). The
Importance of meteorite impact craters in geology?
Earth scienceAsked by: Lynn Sudd Why are meteorite impacts important? In summary, we propose that meteorite impact events are a fundamental geobiological process in planetary evolution that played an important role in the origin of life on Earth. We conclude with the recommendation that impact craters should be considered prime sites in the search for evidence
What is the average cholorphyll concentration for the ocean?
Earth scienceAsked by: Lynn Sudd What are chlorophyll concentrations in the ocean a measure of? The concentration of chlorophyll is an indicator for the amount of photosynthetic plankton, or phytoplankton , present in the ocean. Phytoplankton populations are influenced by climatic factors such as sea surface temperatures and winds. What is chlorophyll in the ocean? Chlorophyll
