• What is weather?Explain.

Weatheris the state of theatmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy.Most weather phenomena occur in thetroposphere,just below thestratosphere. Weather generally refers to day-to-day temperature andprecipitationactivity, whereasclimateis the term for the average atmospheric conditions over longer periods of time.When used without qualification, "weather" is understood to be the weather ofEarth.

Weather is one of the fundamental processes that shape the Earth. The process of weathering breaks down the rocks and soils into smaller fragments and then into their constituent substances.During rains precipitation, the water droplets absorb and dissolve carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic, which aids the erosive properties of water. The released sediment and chemicals are then free to take part inchemicalreactions that can affect the surface further (such asacid rain), and sodium and chloride ions(salt)deposited in the seas/oceans. The sediment may reform in time and by geological forces into other rocks and soils. In this way, weather plays a major role inerosionof the surface.

hope both the answers help

all the best

The atmospheric conditions- tempreature,humidity,rainfall etc. - of a place on a particular day describe the weather of that day. The weather keeps changing every day and may also change several times in a day

WHEATHER IS DAY TO DAY CHANGES IN ATMOSPHERE LIKE THISDAY IS TOO HOT AND NEXT DAY THERE IS TOO RAINFALL IS CALLED WHEATHER.
