What is Earth Science?
Earth science is a broad spectrum of Science, that covers life science and physical science. Life science is all about the study of living organisms and their relationships that include biology, anatomy, ecology, etc. It is the study of the earth and its neighbouring celestial bodies of the solar system.
In a simple manner, the branches of science dealing with the physical constituents of earth and the atmosphere and it is considered to be the definition of earth science.
This subject includes all physical processes that occur on the earth’s surface as well as in its atmosphere. Therefore, earth science involves the entire natural phenomenon like rainfall, storms, hurricanes, drought, floods, etc. Also, the factors that affect these physical processes and the effect of these natural processes on earth and the living organisms are studied under the head.
Importance of Earth Science
The significance of this is understood by knowing the regions that are covered by the different branches of it. Since, the study of the oceans that covers about seventy-one percent of the surface of our planet. It serves one of the most important divisions of the science. The Earth is the only planet which supports life and the only planet where life is said to be continuously sustained. Oceans are considered as the areas of the origin of life on the earth and a major determinant of the earth’s atmospheric condition that serves as determinants of various life process on various parts of the earth. Also, the study of the different fossil forms that are present under the earth’s surface gives us the information about the forms of life present at a geological sense and it also known to establish a bond between the ancestral & the living forms. The rocks that are found in the variety of parts of the earth provides data about the evolution of rocks at ancient times. Hence, it is one among the principal branches of physics to study.
Earth Science Formulas
- The earth’s magnetic field:
\(\begin{array}{l}B=\sqrt{B_{H}^{2}+B_{V}^{2}}\end{array} \) |
Where,
- B is the earth’s magnetic field
- Bv is the magnetic field in the vertical component
- BH is the magnetic field in the horizontal component
