Earth Sciences
Earth is one of the four terrestrial planets in the solar system. It is a very common planet in our solar system and has been identified as one of the four terrestrial planets. It is quite similar to the Earth seen around the sun in that it has a rocky surface and is composed mainly of molten rock. The rocky planet of Earth is divided into two sections, with one section being a warm ocean floor and another being an extremely cold atmosphere (the “oceans”). The other section of the planet is generally a desert.
Earth orbit is elliptical and does not circle the earth at all. Instead, it is a highly irregular orbit that brings the planet closer to the sun. The tilt of the orbit allows the planet to experience seasonal climatic changes that cause tectonic uplift. This is a process whereby heat is stored in the lower crust causing an increase in its freezing temperatures. This leads to widespread melting of the ice that lies below the frozen oceans and this ice gradually rises to the surface spreading out across the planet.
Tectonic uplift occurs when the earth pushes up or down against the sun in order to move it closer to its orbital plane. When the planet grows too big, the move towards the sun causes the solid surface of the planet to solidify (concentrated in the polar regions). When this happens, the planet can be subjected to extreme heat which melts the upper ice layer of the planet and forms a sea, pool of liquid water called a lake (or seas), and clouds. This process can stretch out for millions of years if it occurs on a large scale, however it usually takes place on small scales where the earth is subject to intense heat from the sun.
The continents on earth are built in such a way that they allow the planet to collect heat from the sun and push it back out into the atmosphere. As it moves through the outer atmosphere, the heat travels into the lower atmosphere of the earth and warms it up. This process is continually taking place as long as the earth and sun exist together. On average, about one foot of each day is taken up heating the earth. During winter, as the earth has a higher elevation than the sun, more heat is absorbed by the earth and transferred into the air, as is snow and rain.
An important aspect of earth sciences is studying the solid earth, the composition of which is strikingly similar to that of the solar system. Studying the earth’s composition has many practical applications because it helps us understand whether our planet was created in its present form or whether there are some alterations necessary to the laws of physics. These studies also shed light on how life began and how it might continue to exist on other planets.
Geologists study the rock layers of the earth and determine how they were formed. The study of how the earth sciences fit together in the context of paleoecology is an interesting but complex scientific enterprise. Among the most interesting results from studying the earth are the many relationships that geology has with the other sciences and how we can evaluate past climates and weather, the study of earth’s structural integrity, and the general state of the earth’s atmosphere.
