What is what does hummocky mean?

Hummocky refers to a terrain or landscape that is characterized by small, rounded hills or mounds that are irregularly spaced and vary in size. These hills or mounds are often created by the movement of glaciers or by the deposition of materials such as sand and gravel by water or wind. A hummocky terrain may also refer to an uneven topography caused by the presence of rocks and boulders that have been dislodged and shifted over time. The term "hummocky" is commonly used in geology, geography, and earth science to describe the appearance and structure of certain landforms and landscapes.
