Earth science includes all fields of natural science related to the planet Earth. This part of science deals with the physical constitution of the earth and the atmosphere. Earth science is the study of our planet’s physical characteristics from earthquakes to raindrops and the floods to the fossils. This part of science can be considered to be planetary science with an older history. Earth science encompasses four main branches of the lithosphere, the hydrosphere, the atmosphere and the biosphere each of which is further broken down into more specialized fields.
There are both reductionist and holistic approaches to earth science. Earth science is also the study of the Earth and the neighbors in space. Some of the Earth scientists use their knowledge of the planets to locate and develop energy and mineral resources. Other Earth Scientists study the impact of human activity on earth’s environment and design methods to protect the planet. Some of the scientists use their knowledge about the earths processes such as volcanoes, earthquakes, and hurricanes to plan the communities that will not expose people to the dangerous events.
Earth science can also include the study of geology, the lithosphere and the large-scale structure of the earth’s interior as well as the atmosphere, hydrosphere and biosphere. A lot of the time earths scientists use told from geography, chronology, physics, chemistry, biology, and mathematics to build a quantitative understanding of how the earth works and evolves. Earth science is part of our everyday life and affects it.
For example, the meteorologist’s study’s weather ad watches for dangerous storms. Hydrologists study water and war of floods where seismologists study earthquakes and try to understand where they will strike. Earth scientists often work in the field perhaps climbing mountains exploring the seabed, crawling through caves and or wading in swamps. The scientist measure and collect samples then they record their finding on charts and maps.
The earth is one of the nine planets in the solar system. There are also smaller bodies called asteroids, comets, and meteoroids. All the objects in the solar system orbit around the sun. The earth has a layered structure. The laying can be viewed in different ways such as layers of different chemical composition and layers of differing physical properties. A variety of processes act on and within the earth here we consider these responsible for natural disasters.
Melting is responsible for creating magmas that results in volcanism. Deformation is responsible for earth quakes, volcanism, landslides, and subsidence. Atmospheric circulation is responsible for hurricanes, tornadoes and flooding. There are layers of different physical properties such as: lithosphere about 100km think, very brittle, easily fractures at low temperature.
