Then, when it thaws, the soil subsides vertically, creating these little terraces on grassy slopes. Peaty soils are quite wet and are acidic. Fences and trees bend downhill in the direction of the soil movement. When it is frosty, the moisture in the soil freezes and the ground expands because ice expands outwards at right angles to the slope. The term "landslide" describes a wide variety of processes that result in the downward and outward movement of materials under the force of gravity; this includes materials like rock, debris, earth, mud and peat, or a combination of these.
