Choose the word which is different from the rest.

The answer is D. Moraines.

Beaches, lagoons, and bars are all landforms that are formed by water. Beaches are formed by the action of waves and tides on the shore of a body of water. Lagoons are formed when a barrier island or reef protects a body of water from the open ocean. Bars are formed when sand or gravel is deposited by currents or waves.

Moraines are landforms that are formed by glaciers. They are composed of rocks, boulders, and other debris that have been carried along by the glacier and then deposited when the glacier melts.

Therefore, moraines are the only landform that is not formed by water.
