By being in the same area or Causing weathering at the same time or place
One type of landform formed by wind would be sanddunes. This is the only landform I can think of formed by wind. The wind blows the sand along so that it builds up into a dune perhaps when it hits an obstacle like a small rocky spur and whole deserts can be converted into dunes.
True i think but i could be wrong. hope you get it right!
