This task is about identifying the states of water in different places in the world.
To understand Earth's systems, such as the water cycle, we need to know about the states that water exists in, and the processes that lead to changes from one state to another.
Water can be a solid, or liquid, or gas. These are called states. The state of water is different in different places.
For example, water is mostly in its liquid state in a river. But if the river froze over some of the water would now be in the solid state.
