Exogenic Forces
Exogenic forces are the external forces that shape the Earth's surface by wearing down and rearranging the materials on the Earth's crust. These forces are responsible for the erosion, transportation, and deposition of material on the surface of the Earth. Some of the key exogenic forces include wind, water, ice, and waves.

Volcano
A volcano is a geological landform created by the eruption of magma from beneath the Earth's surface. Volcanic eruptions are caused by the movement of tectonic plates or the release of pressure from a magma chamber. While volcanoes can cause significant changes to the Earth's surface, they are considered endogenic forces as they originate from within the Earth.

Wind
Wind is a powerful exogenic force that plays a significant role in shaping the Earth's surface. The movement of air in the atmosphere causes erosion, transportation, and deposition of sediment. Wind erosion can lead to the formation of sand dunes and the wearing away of rocks and soil. Wind also carries fine particles like dust and pollen over long distances.

Sea Waves
Sea waves are another exogenic force that are primarily caused by the wind. Waves constantly shape and reshape coastlines through the processes of erosion, transportation, and deposition. The energy of the waves can wear away rocks and cliffs, leading to the formation of coastal landforms such as beaches, spits, and sea caves.

Glaciers
Glaciers are large masses of ice that form over long periods of time in areas where snowfall exceeds melting. Glacial movement is an important exogenic force that can reshape the Earth's surface. As glaciers move, they erode the land beneath them, carrying and depositing large amounts of sediment. Glacial erosion can create deep valleys, cirques, and moraines.

Volcano as an Endogenic Force
While volcanoes can cause significant changes to the Earth's surface, they are classified as endogenic forces. This is because volcanoes originate from within the Earth, with magma being expelled onto the surface through volcanic eruptions. The movement of tectonic plates and the release of pressure from magma chambers are the primary causes of volcanic activity. Volcanic eruptions can result in the formation of new landforms such as volcanic mountains, lava flows, and volcanic craters.

Conclusion
In conclusion, the correct answer is option 'A' - Volcano. Volcanoes are not considered exogenic forces because they originate from within the Earth's crust, making them endogenic forces. Exogenic forces include wind, sea waves, and glaciers, which shape the Earth's surface through erosion, transportation, and deposition of materials.
