The Rock cycle is considered an open system because it requires energy and matter inputs from external sources to drive the processes of rock formation, weathering, erosion, and deposition. These external sources include the energy from the sun, water, and other agents that play a role in the continuous transformation of rocks from one form to another.
External energy refers to energy that comes from sources outside of a system. This energy can be transferred to or from the system, impacting its overall energy level or ability to perform work. Examples of external energy sources include mechanical work applied to a system or heat transferred to or from the system.
The Earth's external heat engine is driven by the energy from the Sun. Solar energy is absorbed by the Earth's surface, which then drives processes such as weather patterns, ocean currents, and the water cycle. This energy also contributes to the Earth's climate system and overall temperature regulation.
External factors that influence the cell cycle include growth factors, which promote cell division and proliferation, and environmental stressors, such as UV radiation or toxins, which can induce cell cycle arrest or apoptosis.
Electromagnetic energy is just a different form of energy. So electromagnetic energy might include potential energy. It might refer to the energy of radiation, which isn't potential energy. see external link

External processes of the rock cycle include weathering, erosion, transportation, and deposition. Weathering breaks down rocks into smaller particles, erosion moves these particles to new locations, transportation carries them further, and deposition involves the settling of these particles to form new rock layers.
Sun is the source of energy. Energy cycle comes from it.
External forces that act on rocks in the rock cycle include weathering, erosion, and transportation. Weathering breaks down rock into smaller pieces, erosion moves these rock fragments away from their original location, and transportation carries them to new areas where they can be deposited and eventually form new rocks through processes like compaction and cementation.
The energy source behind the water cycle is solar energy. It is the only energy which initiates water cycle.
solar energy
The sun is the major external source of the Earth's energy. This energy drives the Earth's climate system, including atmospheric circulation and ocean currents, which can in turn influence natural hazards such as hurricanes, droughts, and floods. Solar energy also powers the water cycle, which is essential for many natural hazard processes.
