We, all living things, thrive to survive on the planet Earth, but what actually makes up the Earth? Scientists have discovered that if we yearn to test and discover how we are affected and affect Earth, we first need to acknowledge the 5 spheres. The 5 spheres are the reason we are changed by our surroundings, our environment. The 5 spheres are the geosphere, biosphere, atmosphere, hydrosphere, and cryosphere. To achieve the understanding of how we are connected to our planet, we need to explore our knowledge of the spheres, our key of understanding of Earth’s system and how do different spheres interact with each other? Many scientists view Earth as a “dynamic system.” “On a macro level, the Earth system maintains its existence and functions as a whole through the interactions of its parts, called components.” The four central components are known as subsystems. These subsystems contain; the geosphere, biosphere, atmosphere, hydrosphere, and cryosphere. First and foremost, if we want to learn about the spheres we should start with the geosphere. “Geo” means ground. The exact definition of the geosphere is “the mostly solid, rocky part of Earth.” The geosphere is separated into three parts because of its level of chemical composition. The …show more content…
The biosphere is “the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.” So far there has been no existence of life elsewhere in the universe. Life on Earth depends on the sun, which is the ultimate source of energy. Energy, provided as by the sun brings light and heat, the light is captured by plants, some bacteria and protists, in the phenomenon of photosynthesis. The captured energy transforms carbon dioxide into organic compounds, such as sugars and produces oxygen. The majority of species are “animals, fungi, parasitic plants and many bacteria” which depend directly or indirectly on
Ultimately the development of previous inferences and observations which have developed our current model for the Earth’s composition and interior structure are a key concept in understanding our future developments towards resourcing our planet and understanding how it works to a further degree.
Basically these are the general features of the Earth and I am going to give you

Ecosystems can be as small as a tide pool or a rotting log or as large as a body of water, forest or desert. Each system can consist of a community of plants and animals and this community is sustained by raw materials, chemical elements and water. Each community is surrounded by soil, water, climate and other conditions of the environment. An example of an ecosystem is a pond it supports a community of fish, frogs, insects and plants. Basic food is small organisms and plankton for the fish to consume. If the ecosystem does not maintain a balance it can weaken and the species will suffer. The systems are affected by fire, disease and severe climate changes not including predators and man such as building, pollution and mining.
General Description: Earth may be the most unique of all planets because of the life forms we know exist here and the way they utilize the Suns energy. The Earth is composed of a great amount of water, mostly in the form of oceans, which make up most of its surface. It also contains various gases, of which make it possible for us humans to exist and is a system that exists between plants and animals here.

ECOSYSTEMS: Microbes obtain energy from their environment. Like humans, many microbes do this by eating plant and animal material. A typical microbe buffet consists of waste from humans and other animals, dead plants and animals, and food scraps. Bacteria, fungi and algae all take part in decomposing — or breaking down — this waste material. Without them, the world would quickly be overrun with discarded food scraps, raw sewage and dead organisms.
God made the Earth for us, so we are the centre of the Universe and others moves around us
in order to ascertain how it brought about Earth's thriving ecosystem and how important it
Life according to scientists is “the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death, also the way of life of a human being or animal.”("Life,”) In order for one to have life, one must have the nine characteristics to be considered a living thing. These nine characteristics are; all living things are made up of cells, living things are able to reproduce, living thing use energy, maintain homeostasis, respond and adapt to the environment, grow and develop, have a life span, evolve over time, and are interdependence. All of the nine characteristics have one thing in common, something that is needed for all living things to use, even if they do not know it. This beautiful thing that all living things should value is photosynthesis. Without photosynthesis there wouldn’t consist humans, animals, insects, and most importantly life!
For millions of years, tectonic plates have been determinate of changes in the physical face of the earth, and they continue to do so today. These massive plates move underneath the surfaces of the oceans and the continents, producing earthquakes, volcanoes and uplifts. This paper will discuss the composition, movement and history of tectonic plates, the theory of plate tectonics and its history, and tectonic plates affect the surface of the earth today and will continue to do so in the future.
Biosphere 2 is a supersealed “greenhouse” enclosing an area of 3.15 acres. Exit and entry is through a double airlock. It consists of several different ecosystems within the “greenhouse.” It houses a tropical rainforest, savannah, scrub forest, desert, fresh- and salt-water marshes and a miniocean that even contains a coral reef. This biosphere is inhabited by over 4000 species in all.
The Earth is a home for mankind, a planet sustaining life, and it is also a giant magnet! Magnets in general, no matter what type of magnet it is, have two end faces called poles. Poles are where the magnetic force is most effective. These two poles are known as the north pole and the south pole. Magnets also create a magnetic field from the particles within the magnet. The Earth resembles this same structure. The earth has a geographic north pole and a geographic south pole. Since opposites attract in magnets the south pole of the core of the earth points towards the geographic north pole of the earth and the north pole points towards the geographic south pole of the earth. The core of the earth serves the same purpose as the particles in m...
Earth system refers to the earths interacting physical, biological, and chemical processes. The system consists of land, oceans, atmosphere and poles. The earth system has four spheres, including the geosphere, the hydrosphere, the atmosphere, and the biosphere. The geosphere refers to the solid parts of the earth system, including earth’s rocky crust, mantle, and the metallic core. Within the geosphere is the lithosphere, which only refers to the uppermost layers of solid earth. The uppermost layers of solid earth are the oceanic and continental crust rocks. Just below the crust is the mantle, which is composed mostly of magnesium and iron silicate minerals. The mantle accounts for about 2/3 of the
The biosphere is a closed self-regulating system that integrates living organisms with nonliving components of a planet (Lenkeit). The biosphere is part of the outer shell of a planet and includes the atmosphere, hydrosphere, and lithosphere (answers.com).
