Do plants get carbon from Sun and what makes the sun keep burning and does black carbon affect rainfall?
In reality, Carbon from our food, but where do you think plants get carbon? They don't get their carbon from the soil, or from the sun, or from water. Plants pull carbon out of the air. The Sun survives by burning hydrogen atoms into helium atoms in its core. In fact, it burns through 600 million tons of hydrogen every second. And as the Sun's core becomes saturated with this helium, it shrinks, causing nuclear fusion reactions to speed up - which means that the Sun spits out more energy. Black carbon is formed by the incomplete burning of fossil fuels, bio-fuels and biomass and by natural sources. A recent modeling study shows that increasing black carbon emissions leads to a decrease in low-intensity rainfall in the pre-monsoon season in northeast India while pushing up severe rain.
In fact black carbon is to interfere with cloud formation and the rainfall pattern. It also reduces sunlight that reaches the surface and that is reflected back to the space. Black carbon may change precipitation and surface visibility. Black carbon rapidly reduces precipitation in all layers by strongly absorbing solar radiation. The added heat also reduces the sensible heat flux at the surface and increases the radioactive long wave cooling.Black carbon is also known to interfere with cloud formation and the rainfall pattern. It also reduces sunlight that reaches the surface and that is reflected back to the space. Black carbon may change precipitation and surface visibility. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Nuclear fusion occurs when one proton smashes into another proton so hard that they stick together and release some energy as well. The Sun survives by burning hydrogen atoms into helium atoms in its core. In fact, it burns through 600 million tons of hydrogen every second. And as the Sun's core becomes saturated with this helium, it shrinks, causing nuclear fusion reactions to speed up which means that the Sun spits out more energy. In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth.
