There are many different things in the world. Some of them are living and some are nonliving. The clouds move in the sky.
Snowflakes sometimes spin in the air.
The more it snows the more the snowdrift will grow in the yard. Thaw increases the icicles on the edge of the roof. The things you see outside the window will grow bigger. Despite that they are nonliving things. Nonliving things do not eat, move on their own, or grow.
