At the wide setting, you can use it from a low angle close to the ground to accentuate foreground elements against the larger background. Sure you have seen photos like this, particularly ocean photos where the camera is positioned low near rocks, making them look bigger in perspective than they are with the expanse of the ocean behind. Usually best on these to use around f/8 so all elements from close foreground to distant background are in focus.
At the longer settings of 85-120mm, this will flatten out the scene of more distant landscapes. It will also give you the flexibility of using an f-stop that optimizes the sharpness of the lens so you have razor sharp elements in the background (usually f/5.6 and f/8 for the vast majority of lenses), while positioning some low foreground elements that will remain out of focus which will provide a sense of layers and depth to the landscape image.
IMO zooms make the best landscape lenses as they give you that flexibility on the perspective of the image, and often the visually stunning part of a view in front of you is really just a small section of the scene so with the zoom you can compress that into the full frame eliminating distracting elements around.
Zooms typically have lots and lots of elements, so if shooting into the sun they may flare more than primes. Might be a good idea to carry some ND filters for it so you can reduce the light and flares if shooting into the sun. Also handy to have some strong ND filters so you can perhaps achieve some long exposures as well to blur moving water or slightly blur moving clouds for the more surreal look to a landscape.
