I drew a mountain very simply. 

First, I drew the sky. I colored it in with a soft gradient. 

Next, I drew the nearby land and grass. 

Next, I drew the mountains in the distance. 

I drew it crookedly because you can see the trees at the top of the mountain. 

And I added some more mountains further away. 

Finally, draw a mountain in the distance and you're done. 

If you draw like this, you can draw a simple picture that gives a mountain feel, although it is not a well-drawn picture.
