Earth Science Homework Help
Earth science deals with the study of Earth and geographic evidences grouped under solid Earth Science or Geology, derived from Greek word GEO meaning Earth and logy meaning study of. Earth is a huge system and several billion years old as the determination of its age becomes difficult due to the elimination of older rocks by natural ruins. The technique used to find out the ages of component is known as dating e.g. tree dating – the tree rings found in trunk establishes its age; one ring is equal to a year. Land, water and space bodies, climatic and atmospheric factors comprise earth science. Students often search for Earth Science homework help as most of the times they get homework with urgent deadlines. Ask Assignment Help provides high quality and plagiarism free Earth Science assignment help to students around the World.
The structure of the Earth includes outer crust, mantle (upper and lower) and core (inner and outer). Lithosphere is made of rocks;the major part of the earth as it is formed of crust and uppermost layer of mantle. Tectonic plates are found in the semi-mantle region and collision of these leads to earthquake and melting of crusts to volcanic eruptions thereby destructing natural environment. These explosions and earthquake imparts a low-frequency energy waves known as seismic waves, that determines the precision of the disasters occurred. Seismograph is used to detect and document earthquakes. Students knew these things in basic however completing homework for these topic consume all of their time.
Earth science is one of the major disciplines of science, which expounds on various systems found on planet earth. Though earth is a safer place to live, it has its own non constructiveness. Water covers approximately 70% of earth’s surface and the water mixes with the melting hot mantle to become magma and rises to form volcano. These magma or lava develops into igneous rocks. The other two common types of rocks are sedimentary and metamorphic rocks: sedimentary rocks are sediments of rock particles by weathering and metamorphic rocks by transforming one form into another (metamorphosis). Weathering refers to the process of breaking down of rock and traveling through places by water forces like sea, ocean, water currents and beds.
Sun radiates heat energy to the Earths atmosphere and maintains the temperature of the planet. The factors that affect the heat energy are temperature, energy in motion, earth’s rotations, revolutions and seasons. Air, water and weather also balance the earth’s atmospheric heat. Natural catastrophe is the destruction and damage in nature caused to life and land respectively. The causes for the natural disaster are directly proportional to the human’s maintenance of vegetation and wildlife: proper regulation of natural resource management improves the environment but loss of which leads to biological hazards. Flood and cyclones are predictable whereas earthquake, volcanoes along with tsunami are unpredictable. Natural resources are the daily needs of mankind for better living and are categorized based on origin (biotic e.g. flora, fauna and fossil fuel, and antibiotic e.g. air, land, water and heavy metals) and renew ability(renewable – air and sun, and non-renewable resources – minerals).
Earth Science Assignment Help
Earth science is about the study of planet earth and interaction of the systems within. Earth science falls under Geo-science as this deals about the geographical and geological aspects of earth. The scientists incorporated natural sciences, physics, chemistry, biology and mathematics to provide a quantifiable ratification of the functioning of the earth and its revolution. This subject is not easy as other subjects.. Only those students dealing with Earth Science assignments are aware of this reality. Now Ask Assignment Help provides high quality urgent assignment help to students around the World. 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 faraway places.
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 relation of 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 non constructiveness.
