Earth science is about the study of planet earth and interaction of the systems within. Earth science falls under geoscience as this deals about the geographical and geological aspects of earth. The scientists incorporated natural sciences, physics, chemistry, biology and mathematics to provide a quantifiableratification of the functioning of the earth and its revolution. Lithosphere, hydrosphere, atmosphere and biosphere are the four spheres of earth forming land, water, air and biological systems correspondingly. The sub-categories of earth science include geophysics, soil science, ecology, hydrology and atmospheric science. Earth has an outer crust, upper and lower mantle, and inner and outer core. The major part of the earth is made of rocks, the lithosphere. Tectonic plates, mountain ranges, volcanoes and earthquakes are detailed by insinuating earth crust outline. Tectonic plates are found in the semi-mantle region and their collision leads to earthquake.The crust melts down due to volcanic eruptions thereby destroying natural environment. The earth surface covers 65-70% of water, which during volcanic eruption mixes with molten lava to form solid rocks called igneous rocks. Sedimentary rocks are sediments of rock particles by weathering and metamorphic rocks by transforming one form into another (metamorphosis) are the other two important rocks. Weathering refers to rock break down and flows through sea, ocean, water currents and beds and reaches far away places. Students often need help with earth science and that time they look out for professional experts. We provide assignment and homework help for all sub-topics of Biology Natural resources are the daily needs for better living of mankind. Natural disaster results in destruction and damage to life and land respectively and the reasons are unswerving relationof flora and biota maintenance by living forms especially humans. Flood and cyclones are predictable whereas earthquakes, volcanoes with tsunami are unpredictable natural catastrophes. Minerals are earth’s resources that are solid, inorganic, natural and chemical forms. Rocks are the mineral masses. Heat, pressure, erosion and other forces of earth change the composition of rocks from one form to another and this cycle is referred to rock cycle. The Earth’s climatic alterations have always been the considering factor and the changes takes place due to heat-cold change over. Space science and constellation studies are the integrated fields of earth sciences. From Newton’s Law of Gravitation to rocket revolution, the credibility of the technology in conjoining the land and space has been made possible. Satellite studies explore shape, size, and age of planets and stars. National Aeronautics and Space Administration (NASA) was launched in late 1950’s by the United States Congress, which paved way for comprehending all about space. Stars, galaxies and universe extended the notion of space stating Universe is everything including matter, energy, space and time. Though Earth science explicates various systems of planet earth, it has its own unconstructiveness.
