Sea cliffs: A cliff facing the sea, usually formed by the erosive action of waves at its base.

Meander:a winding curve or bend of a river or road.

Sea Cliffs:
Sea cliffs are vertical or near-vertical rock formations that are formed by the erosion of waves along the coast. They are typically found in areas where the land meets the sea, and they can vary in height, shape, and composition. Sea cliffs are formed through a combination of wave action, weathering, and erosion. The constant pounding of waves against the base of the cliff causes the rock to weaken and break apart over time. This process, known as hydraulic action, is particularly effective in areas with soft or weak rocks. As the waves continue to erode the base of the cliff, the overlying rock becomes unstable and eventually collapses, leading to the formation of a sea cliff.

Meanders:
Meanders are winding curves or bends in a river or stream. They are formed through a combination of erosion and deposition. As a river flows, it erodes the outer bank of a bend and deposits sediment on the inner bank, causing the bend to become more pronounced. Over time, the river continues to erode the outer bank and deposit sediment on the inner bank, causing the meander to migrate downstream. Meanders are most commonly found in areas with gentle slopes and easily erodible banks. They are often associated with floodplains and can create a complex network of channels within a river system.

Earthquakes:
Earthquakes are natural events that occur when there is a sudden release of energy in the Earth's crust. This release of energy can cause the ground to shake, resulting in the shaking and displacement of the Earth's surface. Earthquakes are typically caused by the movement of tectonic plates, which are large sections of the Earth's crust that float on the semi-fluid mantle below. When these plates move past each other, they can become locked due to friction. As the stress builds up, it eventually overcomes the friction and causes the plates to slip, resulting in an earthquake. The energy released during an earthquake is measured using a seismograph, and the intensity of the shaking is measured using the Richter scale.

Volcano:
A volcano is a geological feature that is formed when molten rock, ash, and gases escape from beneath the Earth's surface. Volcanoes are typically found at tectonic plate boundaries, where the Earth's crust is under tension or compression. When the pressure becomes too great, it can cause the molten rock, or magma, to rise to the surface, resulting in a volcanic eruption. Volcanoes can vary in size and shape, ranging from small cones to large mountains. They can also have different types of eruptions, including explosive eruptions that send ash and gases into the atmosphere, and effusive eruptions that result in the slow flow of lava.

Loess:
Loess is a type of wind-blown sediment that is composed of fine particles of silt and clay. It is typically found in areas with a dry climate, such as deserts or semi-arid regions. Loess is formed when fine particles of dust are picked up by the wind and transported over long distances. These particles eventually settle and accumulate, forming layers of loose sediment. Loess deposits are often highly fertile and can be agriculturally productive. They are also important for preserving archaeological sites and fossils, as the fine particles help to preserve delicate materials.
