Introduction
The Earth is the third planet that revolves around the Sun in our solar system and it consists of all of the living beings. Therefore, the Earth is providing shelter and life to all of the living beings and it is also predicting the living beings from the negative aspects that revolve around the galaxy. Therefore, the Earth is a perfect oblate spheroid, actually not round and it is like an irregularly shaped ellipsoid. The equator of the Earth is at 12,756 km and to the pole, it is 12,714km and it is like an egg in shape.
Shape and size of the Earth planet in Physical Geography
The earth is not actually round, it is just like an oblate spheroid, which means it is not perfectly round. The earth is the third planet in the solar system and it is 92,955,820 miles away from the Sun. It is one of the unique planets in our solar system, which only contains life. Therefore, the earth consists of three parts of water bodies around itself and one part of the land. There are 70.8% of water bodies around the Earth and it is very important for the living beings on the earth. The earth is made up of core, mantle and crust, however, the crust of the earth is the thinnest layer from three of these layers. The diameter and circumference are different as the shape of the earth is just like an ellipsoid or oblate spheroid. The poles of the earth are squished and the equator of the earth is a bulge. Along with the help of gravity, the earth pulls all of the mass objects to its centre and as it rotates on its axis the sphere is “distorted” with the help of centrifugal force. The size of the earth has huge importance in increasing the gravity to pull all of the mass objects to its centre.
Terrestrial radiation
Terrestrial radiation can be referred to as the main source of radiation that is available in the vegetation, water and soil. There are major isotopes that concern terrestrial radiation are “potassium”, “uranium” and “the decay products of uranium” like “radon”, “radium”, and “thorium”. Along with the help of natural breakdowns, terrestrial radiation is formed in the earth or natural materials on earth such as groundwater, vegetation, soil and rocks. The earth gets heated through the sunlight and then the earth releases the energies of heat which result in changing the environment on the earth. Terrestrial radiation affects the health of human bodies and it also heats up the atmosphere around the earth.
Importance of earth’s shape in transforming its temperature
The earth is just like an egg and it gets the sunlight directly on one side and another side cannot get the sunlight at the same time. For example, if we hold a flashlight on a globe, it will only light on one side of the particular globe and it will be dark on the opposite side of that globe. Therefore, it is the same, the sunlight can be compared to the flashlight and the globe can be examined as the earth. The shape of the earth is important to carry various types of temperature in the earth’s surroundings. Therefore, the lighted side of the earth will carry more heated temperature rather than the opposite side of the earth. The earth heats more in its equator rather than its poles, which is the main cause of the change in its temperature. The shape of the earth helps to change the climate in different areas of it and it also helps to change the weather in different areas around itself.
Conclusion
The earth’s shapes and size have a huge importance in changing the climate or atmosphere of the earth. Therefore, the shape of the earth also helps to change the temperature as it is just like an egg. The size of the earth also helps to increase the gravity of the earth, which also helps to pull all of the mass objects towards its centre.
