The History of Earth’s Surface

The History of Development of Earth’s Surface

The shape of Earth surface is various and each of it passes difference process. The difference of the process among other are influenced by power and time. The Earth is a planet that has certain characteristic, so it enables the presence of life.

Our Earth was formed about 4.6 billion years ago together with the formation of one solar system called the solar family. One theory called Nebular Hypothesis tells the story in 3 phases:

1. Sun and another planets are still in the form of gas, it is very dense and big fog.
2. The fog rotating and twisting strongly, where the coagulation happens in the center of the circle that then forms the sun. at the same time, another material formed becomes mass that is smaller than the sun that is called planet, it moves revolving the sun.
3. Those materials grow more larger and keep doing movement regularly revolving the sun in one fixed orbit and form the composition of the Solar family.



Earth is one member planet of our solar system. The occurrence process of the Earth is equal to the sun. Because of its volume is smaller than the sun, its formation process is faster. In formation process of Earth, it happens separation base on to its mass. The heavy part forms core that is called barisphere, while the lighter part forms Earth’s crust or often called lithosphere.

In cooling process that reaches 100 Celsius, it happens condensation, then happens rain, after that the rain water fills the lower parts of Earth and forms watery layer called hydrosphere. Besides lithosphere and hydrosphere, the Earth is also covered by air layer or atmosphere and life layer called biosphere.

In carbon era, the continents unite form the big continent called pangae that in Greek means “the whole world”. Since 1900, geologists have known that outer part of Earth’s crust floats on the soft inner layer.
