Of the many ideas of how the Solar System was created, the most commonly accepted is the Nebular premise. This hypothesis states that the Solar System was at one point a gaseous cloud that would develop solid particles over time. These particles would eventually progress into planets (with the exception of Pluto) and more related to our discussion, form what is now known as Earth. As the numerous collisions made impact, the gravitational pull brought objects to the surface. These objects were of three distinct sorts: metal-rich fragments which were iron meteorites, rocky fragments which were stony meteorites and lastly icy fragments which were comets. The numerous collisions that created Earth as well as many other planets is critical impart to understanding the internal energy of the Earth. .
The internal energy of the Earth is very important to the study of Geology. It is internal energy that is the motivating force behind the cause of natural disasters. The colliding fragments mentioned earlier have been credited for being one of the sources of Earth's internal energy. These extraterrestrial impacts utilized kinetic energy which processed heat energy upon impact. These fragment impacts are one of many major internal energy sources of the Earth.
In addition to the extraterrestrial impacts, Earth has a component of internal energy based on gravity. Scientists today believe the Earth was less solidified during the early stages of Earth's development. As Earth became more and more a focal point of tremendous collisions, it compacted itself, allowing Earth to consume less space. As a consequence of consuming less space, Earth compressed its internal energy within. This internal energy works through the surface in a steady fashion.
Besides extraterrestrial impacts and the gravitational compaction, Radioactive decay is furthermore another source of internal energy. The elements that make up the arrangement of the Earth are mostly chemically insecure.
