What is weather? What are some characteristics of weather?
When we talk about weather, we mean the daily conditions in the atmosphere of a local area.
Many conditions make up the weather. A few are cloud cover, wind, humidity, and temperature,
which is how hot or cold the air is. One condition that is important for planning a vacation is
rainfall. Rain is a type of precipitation. Precipitation is water that falls to Earth from clouds. There
are many forms of precipitation, including rain, sleet, hail, and snow. They are all slightly different
based on the temperature of the air as the water falls through it. Rain is liquid water that falls in
droplets. Snow and hail, on the other hand, are particles of ice that fall when it is colder outside. Hailstones are nuggets of falling ice, while rain is droplets of liquid
Sleet is a mixture of rain and snow. Weather is an important part of daily life. It describes the water. Both are forms of precipitation
changing conditions of the environment around us. What is the weather like where you are today?
