World Water Cycle

That´s a video about the Water Cycle:

That´s a picture about the Water Cycle:

1. Evaporation (and transpiration): is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air.
2. Condensation: Water vapor in the air gets cold and changes back into liquid, forming cloud.This is called condensation.
3. Precipitation: occurs when so much water has condensed that the air cannot hold it anymore.  The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.
4. Collection: When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. When it ends up on land, it will either soak into the earth and become part of the "ground water" that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.

Political Map of Europe

A (This) political map of Europe teaches us the 50 countries which is divided the continent of Europe. We shouldn´t confuse it with the map of the countries of the European Union (EU), as some European countries don´t form part of the EU (for example: Russia).
