Firstly, rain when falls on earth contains the dissolved form of carbon-dioxide which causes rainwater to be acidic in nature and also contains carbonic acid.  The rain when erodes the rock, the acid present in it, breaks down rocks chemically and

Any object floats or drowns in water because of its density. Actually at the depth of any liquid, there is an upward force because of the effect of gravity on fluid. If an object falls on it, having less density than the density of fluid, it will float. If the object has higher density than

Snow falls from the sky, but where exactly does it come from? Snow begins in the atmosphere as water condenses into a tiny droplet. As more and more water vapour condenses onto its surface, the droplet grows. Cold air then freezes this water into an ice crystal. Each ice crystal has a unique shape that
