They are all very similar, and can sometimes mean the same thing. However some are also more specific than others. -A landscape is a view, but usually very wide. Like a photo from a mountain. -Scenery can sometimes refer to nature. Or the features of a landscape. -A view usually means that you can see very far. Again, they are all very similar and related. Often any of them will work in the context.

I look at them as the same thing just on a different scope. "view", "", " and " 1)landscape on a large scale, a large piece of land that can be seen. Perhaps from a helicopter of very large/tall building 2)scenery slightly smaller scale than landscape, also a large range of land, often countryside. If I'm driving through the countryside I might say, "look at the beautiful scenery"....what I see may be mountains, or a field of flowers, or the oceanfront beach. 3)view on a smaller scale, also a range of land, usually referred to what you see out of you own bedroom window, or off the balcony/terrace. 4)sight, in this context one might say, "now that's a sight to see!" they would be referring to any of these (landscape, scenery, view) Keep in mind that these words really can be interchangeable. I hope this helps :)
