Because they are at the intertropical converge zone. Which is where air rises due to direct solar radiation causes water vapor to fall back to earth as rain.
Acid rain
caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
Answer:
1) the quality of being eccentric...2) deviation of a curve or orbit from circularity
Explanation:
When scientists discuss the great oxygenation event, they are referring to a time when the transition from the mildly reducing Archean atmosphere-ocean system to the oxygenated atmosphere and shallow oceans of the early Paleoproterozoic that started between ~2.4 and 2.3 Ga and ended between 2.1 and 2.0 Ga.
- here The Great Oxidation Event, also called the Great Oxygenation Event, the Oxygen Catastrophe, the Oxygen Revolution, and the Oxygen Crisis, was a time interval when the Earth's atmosphere and the shallow ocean first experienced a rise in the amount of oxygen.
- in this event Gradually, the accumulated oxygen started escaping into the atmosphere, where it reacted with methane. As more oxygen escaped, methane was eventually displaced, and oxygen became a major component of the atmosphere.
- The Great Oxygenation Event (GOE) was the creation of free oxygen in our atmosphere. It was caused by cyanobacteria doing photosynthesis

Higher silica content means higher viscosity. But lower temperatures and low gas content mean higher viscosity. Hence, lower viscosity and low gas content mean higher temperature of magma.
