Importance of meteorite impact craters in geology?

Asked 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?

Asked 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?

Asked 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,

Is there a table available for the maximum potential intensity of hurricanes?

Point source pollution model for South America

Asked 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?

Asked 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

Do flights affect tides?

Asked by: Brian Fabijan What has the most effect on tides? The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Is flying over the ocean smoother? Flights Over Calm Waters and Oceans If the waters over a particular patch of ocean are calm, therefore, the flight

Earth History Book

Asked by: Brian Fabijan What is Earth’s history called? geologic history of Earth geologic history of Earth, evolution of the continents, oceans, atmosphere, and biosphere. The layers of rock at Earth’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed.

Estimate the flow velocity of a river with satellite images

Asked 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?

Asked 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
