Introduction
The earth is one of the main eight planets that revolve around the sun on their orbits. The earth not only spins around the sun, but it also rotates on its axis, which results in days and nights. One of the most interesting features of the earth is its center. The center of the earth is known to be a solid sphere that is hot and dense, and which mainly comprises iron deposits and traces of nickel.
The center of the earth is large, and it measures approximately 2400 kilometers in diameter. This is about 20% of the diameter of the earth (Cain 1). This paper describes a trip to the center of the earth as well as the features that can be observed during the trip, such as minerals, temperature, and caves.
The Trip
One is likely to experience a lot of things on this particular trip to the center of the earth. Firstly, one will get to know how the earth, which is one of the main planets, was formed. The earth was formed through the convergence and melting of large pieces of rocks that broke from the newly forming sun. During the formation of the earth, heavy metals such as iron and nickel sunk the earth to form its center, which is always hot and dense (Cain 1).
The center of the earth is very hot as a result of the materials that are found in it. The further a person goes toward the center of the earth, the hotter it becomes. It has been proven that the temperature within the first few feet, which is about 100 feet below the earth’s surface, is uniformly cool and tolerable.
However, past the 100 feet, the temperature begins getting hotter since the rocks and other materials found at this point are warmer than those found on the surface. The center of the earth is estimated to be at a temperature of 40000C (Cain 1). In this trip, it is important to carry a thermometer or any other device for measuring the temperature of the earth at different points.
Apart from the uniquely high temperature, another interesting thing regarding the center of the earth is the seismic waves, which travel across the interior part. It is the data contained in these seismic waves that are analyzed by scientists to predict when an earthquake is going to occur.
The analysis of the information extracted from these waves can also be used to make assumptions regarding the materials found deep in the center of the earth; these waves are believed to pass through these materials, which are found at the center of the earth (“Deepest Caves” 1). In this trip, seismographs are some of the important equipment that will be carried to detect seismic waves.
Other interesting features in the center of the earth are the caves in it. Good examples of these caves are Krubera-Voronja Cave and Illuzia-Snezhnaja-Mezhonnogo. Voronja is currently considered the deepest cave in the center of the earth. Voronja measures approximately 2129 meters. Voronja is in the Arabika Massif of the Gagra Range, which is found in Georgia. Illuzia-Snezhnaja measures about 1753 meters, and it is found in Abkhazia, Georgia (“Deepest Caves” 1).
Conclusion
This paper describes a trip to the center of the earth. There are several things that one can observe during this trip. The temperature at the center of the earth is said to be as high as 40000c. The main minerals found on the center of the earth are iron and nickel deposits. The center of the earth also contains caves, such as Voronja, which goes as deep as 2129 meters.
