well it depends. the rain can be this or that haha
No, rainwater would be pure water if it weren't for the contaminates is picks up from the air while falling.
No, water is Hydrogen and Oxygen. There are no vitamins in water.
Rain water is collected through a process named Rainwater harvesting. Here rainwater that falls on the roofs are collected through pipes and ultimately stored in large tanks. These are called harvesting tanks also.
erosion
The rainwater is more acidic after passing through polluted air.
zone of saturation
Water conservation is promoted through rainwater harvesting.
you get vitamin c through fruits and vegetables:D
Vitamin B12- seawater contains this in relatively large amounts and therefore it is logical in saying that this is evaporated and then present in rainwater (depending on the wind direction and the original water source).
Rainwater can cause widespreed weatheing. loose soil and bare land get the most affected doring heavy rainfall.
no vitamin c is a water soliable vitamin it will simply pass through
There is no vitamin that is absorbed through uv rays , but when uv light falls on skin , it produces vitamin D in skin by a photochemical reaction .
