What can serve as a drainage divide between adjacent watersheds

A hill, ridge or a mountain can serve as a drainage divide between adjacent watersheds.

To add, a watershed is the area of land (catchment area) that captures rain and snow, and then

stores, filters, seeps or drains this water into a common water body (marsh, stream, river, or

lake).

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
