This is precipitation, part of the water cycle.
Clouds are made of tiny water droplets or ice crystals that have condensed from water vapor in the air. The water droplets or ice crystals gather together to form visible clouds that we see in the sky.
Water vapor in the sky can condense into tiny droplets or ice crystals, forming clouds. When these droplets grow larger and coalesce, they eventually fall to the ground as precipitation, such as rain or snow. This process is a key component of the water cycle, contributing to weather patterns and climate.
Clouds are formed when water vapor in the air condenses into tiny water droplets or ice crystals, which then gather together to form visible masses in the sky. Factors such as temperature, air pressure, and humidity influence cloud formation and appearance.
That describes a cloud.
Snow
you call them icecaps that fall from the sky
Hail.
snow or hail
Hail
no Ice particles fall from the sky but Ice crystals form on the ground.
Ice crystals that fall from the sky are called snowflakes.
Clouds do not fall from the sky because they are made up of tiny water droplets or ice crystals that are lighter than the surrounding air. These droplets and crystals are held aloft by rising air currents and wind patterns in the atmosphere.
You may be referring to snow. If you come from a climate where you have never seen it, it is water vapor frozen into whitish-colored ice crystals, and in winter, it falls in flakes onto the ground.
Tiny frozen pieces of hydrogen and oxygen can form snowflakes, which are intricate ice crystals that fall from the sky when water vapor freezes in the atmosphere.
