The bottom is like the floor of your house. When you stand on the floor, you are at the bottom of your room. The bottom is the lowest part of something. If you have a cup, the bottom is where it sits on the table. It’s the part that holds everything up.
Picture a tall tree. The bottom is where the tree touches the ground. It’s the base that keeps the tree standing tall and strong. Without the bottom, the tree would fall over.
Think of your toy box. The bottom is where all your toys rest when the box is full. It’s like a bed for your toys, keeping them safe and snug.
Even in a big ocean, the bottom is the very deep place where all the sand and rocks are. It’s a place where fish and other sea creatures might live. The bottom is important because it supports everything above it, just like how your feet support you when you stand.
