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

Which tropical evergreen trees shed the maximum amount of foliage year-round?
Earth scienceAsked by: Jermyn Dawson What forests keep their foliage throughout the year? An evergreen forest is a type of forest whose trees maintain their leaves throughout the year. This means, regardless of the season, these trees will be found with leaves or needles. The trees of an evergreen forest can be conifers, hemlock, eucalyptus, cycads,

Point source pollution model for South America
Earth scienceAsked by: Jennifer Harwalkar Which is an example of a point source pollution source? The United States Environmental Protection Agency (EPA) defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Examples include smokestacks, discharge pipes, and drainage ditches. What are 4 possible sources of point source

How does Antarctica stay frozen?
Earth scienceAsked by: Jennifer Harwalkar The simple answer is that Antarctica does not receive enough heat, since surface is at a low angle to the incoming sunlight. Additionally, it is covered with snow & ice, which reflects a lot of the incoming energy. What keeps Antarctica frozen? The Antarctic Circumpolar Current, or ACC, is the strongest

Estimate the flow velocity of a river with satellite images
Earth scienceAsked by: Kemar Jones How do you measure the flow velocity of a river? Multiply the average depth of the stream by the width of the stream to find the area in ft2. Divide the distance traveled by the average travel time to find the velocity of the stream in ft/sec. How do you calculate

How is the specific heat of a wet bulb determined?
Earth scienceAsked by: Kemar Jones How is wet-bulb temperature determined? Wet Bulb temperature can be measured by using a thermometer with the bulb wrapped in wet muslin. The adiabatic evaporation of water from the thermometer and the cooling effect is indicated by a “wet bulb temperature” lower than the “dry bulb temperature” in the air. How
