Alright kiddo, have you ever seen water flowing down the street after it rained a lot? That's kinda what a flood is, but a much bigger version.
Think of the ground as a big sponge that can hold water. But what happens if it rains a LOT and the ground can't hold all that water? It starts spreading out and flowing into rivers, lakes or other bodies of water nearby.
When this happens, those bodies of water can't hold all that extra water either, so they start overflowing and flooding nearby areas.
Floods can be caused by heavy rainfall or even melting snow. They can also be caused by things like dams breaking or big waves from the ocean, especially during a storm.
Floods can be very dangerous, especially for people who live near rivers or in low-lying areas. They can damage homes and buildings, sweep away vehicles and even cause people to drown.
That's why it's important to pay attention to the weather and stay safe when there's a flood warning in your area. Remember to always listen to adults and follow their instructions during a flood. Stay safe, little buddy!
