A warning system is like a super smart friend who tells you when something bad might happen so you can be prepared.
Imagine you are playing outside with your friends and suddenly you see dark clouds in the sky. Your super smart friend, the warning system, tells you that there might be a storm coming soon. This way you can get ready and go inside to keep safe.
Similarly, there are different types of warning systems for different kinds of dangers. Some warning systems alert us if there is a fire, earthquake, or even if there is a dangerous animal nearby. These warning systems are designed to help us protect ourselves and stay safe. They work by using special sensors and technology to detect changes in the environment, and then sending out a message or alarm to warn people to take action.
In short, a warning system is like a helpful friend who tries to keep us safe by warning us when something bad might happen.
