Explain how the outward flow of energy from the Earth’s interior drives the process of plate Tectonics

All the earth processes are a result of energy flow and mass circulation in and outside of the earth system. Plate tectonics is an earth process that involves the movement of the lithosphere caused by internal processes inside the earth’s mantle (Kent C 154). This is as a result of convection currents within the earth’s crust caused by the heat in the crust. This heat in the crust is due to the initial heat during the earth’s formation and through the radioactive process. The earth’s core is made of radioactive elements such as uranium which decay and ...

1) Explain how the outward flow of energy from the Earth’s interior drives the process of plate tectonics?

The outermost layer of earth, or lithosphere, is broken up into tectonic plates. The boundaries of the plates and their movement leads to the formation of earthquakes, volcanic activity, creation of mountains, and the formation of oceanic trenches. Tectonic plates are formed from either oceanic crust or continental crust, with many containing both. The movement of the plates varies from 0-100mm in a given year. The movement of these plates comes from the outward energy of flow that comes from earth’s central core. Radioactivity produced from elements within earth’s core, such as uranium, decay and release energy. The ...

1) Explain how the outward flow of energy from the Earth’s interior drives the process of plate tectonics?

The earth’s composition consists of a crust, mantle and core. The earth’s core consists of elements like uranium which are radioactive. Due to the phenomenon of radioactivity, these elements decay and trigger a reaction. Because of this a large amount of energy is produced in the core and inner core of the earth. Because of this energy, the core of the earth is very hot and in a molten state. This heat is transferred from the core to the crust by the process convection currents formed in the molten core, creating a cycle of rising and falling of the molten material. This ...

2) There are justifications on the presence of the moon. Perhaps, collision-ejection theory of the moon gives an explains on the issues. The theory asserts that the moon exists due to the formation of debris ejected from the earth, especially when objects crushed. Collision-ejection theory claims that the newly formed earth collided with mars at an angle, which splashed the layers of the earth surface into the orbit around it. This implies that the Earth crust and mantle formed the moon though condensation. There are various facts on the moon that the theory is consistent with. Some of the ...
