(D) weather

Extra: Weather refers to the short-term (minutes to weeks) state of the atmosphere, including temperature, humidity, precipitation (rain, snow, etc.), cloudiness, visibility, and wind. It's what you see outside from day to day and it can change frequently. For instance, one day it might be sunny and warm while the next day could be cold and rainy.

Climate, on the other hand, is the average of the weather over a long period of time (usually 30 years or more) for a particular region. Climate tells us what the weather is typically like in a specific area, allowing us to expect certain types of weather at different times of the year.

Drought is an extended period where there’s a deficiency in a region's water supply. It can be due to less precipitation than usual, changes in wind patterns, or human activities. Droughts can last for months or even years, and they can have serious environmental, economic, and social impacts.

Precipitation is any product of the condensation of atmospheric water vapor that falls under gravity, including rain, snow, sleet, and hail. Precipitation is a vital component of how water moves through Earth’s water cycle, connecting the ocean, land, and atmosphere. It's also critical for all life on Earth, as it affects the availability of fresh water for drinking and agriculture.
