Why is the Rock cycle an open system?
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.
What does external energy mean?
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.
How is the earths external heat engine driven?
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.
What are two examples of external factors that influence the cell cycle?
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.
Is electromagnet potential energy?
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
Is external reproduction the same as a life cycle?
no
Where does the energy cycle comes from?
Sun is the source of energy. Energy cycle comes from it.
What is the external processes of rock cycle?
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.
What is the energy source that drives the watre cycle?
The energy source behind the water cycle is solar energy. It is the only energy which initiates water cycle.
What are the external forces that acts on the rocks in the rock cycle?
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.
What is the external energy of the earth?
solar energy
What is the source of energy the carbon cycle?
Solar energy is the source of energy behind the carbon cycle.
