The Earth comprises many spheres of subsystems, which associate with each other to develop a composite and spontaneously changing system of the Earth. The processes taking place in the system of the Earth occurs on spatial scales changing from fractions of millimeters to thousands of kilometers, and on time scales, which varies from milliseconds to billions of years.
The examples of instantaneous scales are a rotation of the Earth, breathing, an earthquake.
The examples of long-term scales are making coal and plate tectonics.
The system of the Earth is featured by various overlapping cycles in which matter is recycled again and again. The cycles involve interactions between multiple spheres and systems. The examples of cycles are rock cycle, day and night, and seasons.
Volcanoes discharge a huge concentration of particulate matter into the atmosphere. These particles function as nuclei for the development of droplets of water (hydrosphere). The rainfall, that is, hydrosphere usually upsurges after an eruption, initiating growth of the plant (biosphere). Thus, volcanoes and volcanic activities are a good illustration of system interactions.
Three examples of Instantaneous Scale (time) of the earth are
- Pliocene Scale: This is the geologic timescale that extends from about 5 million years to 2.6 million years before the present (BP).
- Miocene Scale: This is the first geological epoch of the Neogene Period.
- Oligocene Scale: This geologic epoch of the Paleogene period spans 33.9 Million years to 23 million years BP.
Examples of two long-term scales in earth's systems are
- Archaean Scale: Right from the history of the earth, this refers to the second out of four geologic eons. It spans 4,000 to 2,300 million years ago
- Protorezoic Scale: This period is said to have ended between 2.5 billion to 540 million years ago. It is usually divided into three eras.
- Shifting of tectonic plates
Examples of three cycles of earth's systems
Examples of the earth's cycles are:
- The Rock Formation Cycle;
- The Water Cycle and
- The Carbon Cycle.
Why are volcanoes and volcanic activity are a good examples of system interactions?
Volcanoes are formed when magma from inside the Earth's upper mantle works its way to the surface. This involves tectonic movement as well as huge mantle plumes. Taken from a helicopter view, one can easily see that these activities show a continuous operation of the earth's processes.
