Give three instantaneous scale (time) examples of Earth's systems, two long-term scale (time) examples of Earth's systems, and three examples of cycles of Earth's systems. Why are volcanoes and volcanic activity a good example of system interactions? (Site 1)

Lithosphere , hydrosphere , biosphere and atmosphere.

Explanation:

Examples of earth's system are lithosphere refers to land, hydrosphere refers to water, biosphere refers to living things and atmosphere refers to air.  volcanoes and volcanic activity are good example of system interactions because in this volcanic activity lithosphere interact with atmosphere. Due to volcanic eruption, carbondioxide gas releases and goes to the atmosphere so we can conclude that volcanic activity is a good example of system interactions.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
