This is some of the ways people use the earth and their connection between each other .It shows how people use the earth to help them survive . And an example would be how farmers use groundwater for their crops. We also use ground water as tap water for drinking or cleaning.

I think the hardest one to understand would be location. I think this  because at first it can be very hard to find absolute location and use coordinates so thats why its hard for me. And an example is when i had the find the coordinates of boston from the atlas.
