Bottom type

Okay, let me explain what bottom type means in a way that a 5-year-old would understand. So, you know how you have different types of shoes like sneakers, sandals, and boots? Well, just like that, there are different types of land and water surfaces called "bottom types".

For example, some water surfaces have a sandy bottom type where the bottom is made up of small grains of sand. Some water surfaces have a rocky bottom type where the bottom is made up of big rocks. Some water surfaces have a muddy bottom type where the bottom is mucky and soft like clay.

Bottom types are important because they affect what kind of animals and plants can live in a certain area. Some animals and plants can only survive in certain bottom types because they need specific things to live, like food or shelter. So, scientists use bottom type to help understand and protect different habitats and the creatures that live there.
