- from Lakes
Lakes are not spread evenly over Earth’s surface. South America does not have many lakes. That is because the Amazon River takes away most of the water. Canada has almost half of the lakes in the whole world. Glaciers carved out most of those lakes.
How does water get into a lake? It can come from different places. It could come from rivers, underground streams, rain, or melting ice and snow. It could come from some or all of these. The water source affects how long a lake will last. So does how it formed.
