The highness or lowness of acidity in water soluble substances
New York City has produced the most killers.
Hydrothermal Vents occur along divergent plate boundaries on the ocean floor. Hydrothermal vent systems give off plumes of hot, mineral-laden water with temperatures as high as 350 degrees Celcius. The water is ejected through a spout known as black smokers. Metal-rich minerals precipitate out of the circling sea water and forms ores of copper, zinc and iron.
Answer:
B. Isostatic equilibrium
Explanation:
Isostasy is a state of balance or equilibrium between the lithospheric plate and the underlying mantle, the asthenosphere.
Due to the weight of the lithosphere, part of it sinks into the plastic asthenosphere and settles to an equilibrium position. This is what causes changes and differences in elevation on the earth.
As with all natural processes, the earth in itself tries to achieve stability and equilibrium in all it parts. The crust and a portion of the mantle forms the brittle lithosphere. The lithosphere floats on the plastic mantle. Due to density contrast, portions of the lithosphere tends to sink into the mantle from time to time. The lithosphere reaches a point where it no longer sinks and establishes an equilibrium with the asthenosphere.
This isostatic adjustment that occurs within the earth is responsible for the changes in elevations from places to places.
When portions of the crust gets eroded, it becomes lighter and rises up. When materials are deposited in adjacent areas or glaciers forms, they add increasing weight to the crust and causes it to further settle within the asthenosphere.
A. This is because these formations occur on the surface and can range from mountains to forests.
