Glaciation refers to the process of the formation, advance, and retreat of glaciers. It is a key process in shaping the Earth's landscape and has played a significant role in the geological history of the planet.
Glaciation is primarily caused by variations in the Earth's orbit, known as Milankovitch cycles, which affect the amount and distribution of solar radiation received by the Earth. These variations lead to changes in global climate and can trigger periods of glaciation.
Glaciation has a number of significant effects on the landscape, including the formation of u-shaped valleys, moraines, and other glacial landforms. It also impacts global sea levels and can lead to the creation of large ice sheets and ice caps.
