When the sulfuric acid molecules either spontaneously nucleate or condense on existing aerosols, they can grow large enough to form nuclei for raindrops and precipitate as acid rain. Rain containing elevated concentrations of SO 2 kills vegetation, which then reduces the ability of the area's biomass to absorb CO 2 from the air. It also creates ...
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...
Sulfuric acid rain in the atmosphere of Venus evaporates before reaching the ground due to the high heat near the surface. [2] Similarly, virgae happen on gas giant planets such as Jupiter . [ citation needed ] In September 2008, NASA's Phoenix lander discovered a snow variety of virga falling from Martian clouds.
Laze is acid rain and air pollution arising from steam explosions and large plume clouds containing extremely acidic condensate (mainly hydrochloric acid), which occur when molten lava flows enter cold oceans. [1] [2] The term laze is a portmanteau of lava and haze.
On the closing phase of the classic Wilson cycle, two continental or smaller terranes meet at a convergent zone. [6] As the two masses of continental crust meet, neither can be subducted as they are both low density silicic rock. As the two masses meet, tremendous compressional forces distort and modify the rocks involved. [7]
However, in 2007, two independent teams of researchers came to opposing conclusions about the likelihood of plate tectonics on larger super-Earths [114] [115] with one team saying that plate tectonics would be episodic or stagnant [116] and the other team saying that plate tectonics is very likely on super-earths even if the planet is dry.
The mechanism involved in the formation of cap carbonates is not clear, but the most cited explanation suggests that at the melting of a snowball Earth, water would dissolve the abundant CO 2 from the atmosphere to form carbonic acid, which would fall as acid rain.
