Relic cliffs are cliffs that used to be active (Eroded) when the sea reached the raised beach beneath it. (Higher sea levels) Now these cliffs are relict because they receive no erosion and have vegetation on them.

Relict cliffs are geological features that were formed by erosion and are now no longer actively being eroded. They often represent the remnants of ancient landscapes that have undergone changes over time, such as changes in sea levels or tectonic activity. Relict cliffs can provide valuable information about past environments and help geologists understand the geological history of a region.
A person who studies cliffs is called a geologist or a geomorphologist, depending on the specific focus of their research.
Cliffs can be formed by various processes, including erosion. Erosion slowly wears away the rock, leading to the formation of steep cliffs over time. Additionally, factors such as weathering, tectonic activity, and sea level changes can also contribute to the formation of cliffs.
Nipekamew sand cliffs are formed by erosion processes, where the sand grains are deposited by wind or water and then carved into steep cliffs by the elements. Over time, the constant abrasion from wind and water shapes the sand cliffs into their distinctive formations.
Steep cliffs are often carved out by natural processes such as erosion from wind, water, and ice. These processes wear down the rock over time, creating the characteristic steep, vertical faces of cliffs. Geologic events such as tectonic activity or volcanic eruptions can also contribute to the formation of steep cliffs.
Cliffs can be protected from erosion by constructing seawalls, adding riprap or rock armour at the base, planting vegetation on the cliff face, and controlling surface water drainage to reduce erosion. Regular monitoring and maintenance are also important to ensure these measures remain effective in protecting the cliffs.
