Answer 1

Answer:

Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. ... Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time.

Adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment.” Living things are adapted to the habitat they live in. This is because they have special features that help them to survive.

Climate is the long-term average of weather, typically averaged over a period of 30 years. More rigorously, it denotes the mean and variability of meteorological variables over a time spanning from months to millions of years.
