transformation

Cloud Small droplets of water vapor that condense on objects they come in contact with.

Fog is small water droplets formed by condensation of water vapor, floating in the low altitude.

Dew vapor is condensed into small water droplets that float high in the sky.

Frost is ice crystals formed by condensation of water vapor at low altitude below 0℃.

Snow is ice crystals formed by water vapor at high altitude being condensed and solidified below 0℃.

Ice is ice crystals formed by freezing and solidification of water when its temperature drops below 0°C.

Now, we know:

Water can go from gaseous to liquid state

For example: water vapor in the air condenses into clouds, fog, and dew.

Water can go from gaseous state to solid state

For example: water vapor in the air condenses into snow and frost.

Water can go from liquid to solid state

For example: liquid water freezes into ice.

The water in the rivers flows into the ocean day and night, but the water in the ocean is never full or overflows. The water in the rivers never stops flowing. What is the reason for this?

Can you provide your own explanation?

Because the water in the ocean is constantly evaporating, the water vapor that evaporates into the air continues to fall down in the form of rain, snow, etc., and this cycle continues. Therefore, the water in the rivers never runs out, and the water in the oceans never fills up or overflows.

Think about it and talk about it:
