Some natural resources are known as renewable resources. This means that even though we keep using them, they will not easily run out. They are replaced naturally. Some examples of renewable resources can be seen below.
Sunlight is a renewable resource because it will not run out no matter how much we use it. Plants use sunlight to grow. We can also use sunlight to make electricity.
Water is a renewable resource. It gets recycled naturally and used over and over again.
Trees are a renewable resource. We can plant trees to replace the ones we cut down.
