Limitations on mineral precipitation from solution

Asked by: Neil Edwards What happens when a mineral precipitates from solution? Precipitation is the reverse process, in which ions in solution come together to form solid minerals. Precipitation is dependent on the concentration of ions in solution and other factors such as temperature and pressure. The point at which a solvent cannot hold any

Why are there different vertical gradients of temperature in different layers of the atmosphere?

Asked by: Neil Edwards Temperature rises with altitude in the stratosphere because this is where the ozone layer exists. The troposphere is primarily heated from below. In contrast, the stratosphere is primarily heated from within via absorption of ultraviolet sunlight by oxygen and ozone. Why do the different layers of the atmosphere have different temperature

What would happen if Earth suddenly stopped rotating and revolving at the same time?

Asked by: Chris Pederson At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes. What will happen if the Earth stops

How much energy would be required to actively reduce the temperature of the oceans of Earth by 1℃?

Asked by: Alejandra Miller How much energy would it take to heat the ocean by 1 degree? Making a rough approximation, assuming the specific heat capacity of sea water is about 3,900 Joules per kg per degrees Celsius and the total mass of the oceans is 1.4×1021kg this would mean that it would take 5.5×1024Joules

What type of mammal does this fossil tooth belong to?

Asked by: Alejandra Miller What type of teeth are found in mammals? Most mammals have three kinds of teeth: incisors used for grabbing, cutting and gnawing; canines used for stabbing and tearing; and premolars and molars for grinding and shearing. The type of teeth a mam- mal has will determine how and what it can

Are there any geological periods found on top of each other that have dinosaurs of that period with in them?

Asked by: Rodney Randall What part of geologic time is represented by dinosaurs? The ‘Age of Dinosaurs’ (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods. What periods and eras have dinosaur fossils? Dinosaurs appeared and disappeared during the
