By, for example, draining into rivers.

In a mountain. A river drains a large area of the landscape so it has many sources, but the label "the source" is often placed on the part that is furthest inland. In the USA, there is a divide along the rocky mountains. On the west side, water will eventually flow to the pacific ocean, on the east side it will flow to the atlantic. So the source of say a river in California, could be no further east than the rocky mountains.
Death Valley has the rocky mountains next to it. The mountains are taller than the valley so they block the rain and cool winds from making death valley cooler so it has a hot and dry climate. Tall mountains do block the rain and cool winds but they are not the Rockies. To the West are the Panamints and to the East are the Funeral Mountains.
Once rain has fallen, water often returns to the ocean from collection in rivers and lakes. Sometimes water falls directly into the ocean as rain.
The Appalachian Mountains are older and more eroded than the Rocky Mountains.
No. Only PURE WATER evaporates from the ocean. It evaporates, rises into the atmosphere, and eventually cools down, condenses, and falls as rain. It may have some chemicals other than water in it, but they were picked up from the atmosphere. So, in a nutshell, only water rises from the ocean to make clouds/rain. The salt is left behind.

They aren't! Most deserts in the United States are located on the western side of the Rocky Mountains or eastern side of the Sierra Nevada Mountains. The Sierras block Pacific moisture from reaching inland, creating a rain shadow.
