Ground slope

Ground slope is the way the surface of the ground is angled. Let's say you are playing with toy cars on a big hill. If the hill is a little bit tilted, your car might roll downward slowly. But if the hill is very steep, your car will roll downhill really quickly. That's because of the slope of the hill. The ground slope around your house is also important. If it is too high on one side of your house, when it rains, the water may flow down towards the house causing floods or making the house damp. So, it's very important to make sure that the ground slope around your house is balanced and not too steep.
