Cliffs warmed by the sun are good for glider pilots because it keeps them up. This happens with a process called thermal radiation. This is when the heat from the sun energy radiates. Thermal Radiation can also be heat from the sun bouncing off something, because the heat that bounces off that thing is thermally radiating through the air. This process can also happen with glider piloting. When the heat from the sun bounces on a cliff, it warms the cliff. This heat then bounces off it and creates a draft. The draft radiates in the air until it reaches the glider pilot and it then keeps the glider pilot up. This is why glider pilots have to be near a cliff or mountain to stay in the air. If they didn't do this or this process wasn't done. Eventually the glider pilot will fall and will be severely injured. So this process is really important for all things not just glider pilots.

Chemical weathering causes a face to form on a cliff.
A cliff retreat is a form of natural erosion. Rocks in the face of the cliff are broken down by wind and water (rain, waves, etc). The material in the cliff is loosened, and parts of the cliff face collapse. Eventually, an entire section of the cliff will fall into the sea, meaning that the cliff edge has retreated. The pace of cliff retreat is determined by the strength of the rocks in the cliff face, more than the cliff's height. It also most often occurs where the base of the cliff is continually being saturated by water, weakening the rock further.

That would be a cliff. A cliff is a high, steep face of rock or earth that drops off abruptly. cliffs are typically found along coastlines, mountains, or in canyons.
