Surface water

Imagine water that lives on the land, not in the big ocean. That's surface water! It's like the water in your bathtub, but way, way bigger. This water forms puddles after rain, streams that wiggle through fields, and huge lakes where you might go swimming. It's all the water you can see sitting right on top of the ground.

Most of this water starts as rain or snow! When the weather gets warm in spring, the snow melts and rushes down hills into streams and rivers. Sometimes, water soaks into the ground, but a lot of it stays on top. It's like when you spill juice on the table – some might drip off, but some stays right there.

Surface water is like a giant drink for our planet. We use it to drink, to help plants grow in farms, and even for fun things like swimming and boating! It's also home to fish and other animals. Without surface water, it would be very hard for people and animals to live.

Some surface water is always there, like big lakes and rivers that never dry up. Other water is like a surprise guest – it only shows up when it rains a lot, like little creeks that disappear when it's sunny for too long. Humans also make their own surface water, like ponds in gardens or big lakes behind dams.
