The Biosphere, Biosphere And The Hydrosphere Essay

There are three main layers on the Earth. The first is, the crust, the outer layer of Earth. It’s everywhere, on dry land and the ocean floor, however it’s

The lithosphere is defined as the rigid outer part of the earth, consisting of the crust and the upper mantle; it is the solid, out part of earth. The picture

On March 23, 2010, President Obama signed into law H.R. 3590, the Patient Protection and Affordable Care Act. Since the induction of the Affordable Care Act the Mayo Clinic reached a new goal of 63 million patient services in 2013. (Mayo Clinic , 2014) There has been substantial growth as seen in 2011 they reported just over 20 million patient services. (Mayo Clinic , 2014) The Affordable Care Act has allowed those patients that could not afford health insurance and or issues with pre-existing conditions to finally be able to seek out treatment with the Mayo Clinic. The Mayo Clinic had recognized early on that there would need to be health care reform to ensure the future of quality patient care. In 2006 the Mayo Clinic started the

“The early Earth was probably partially or largely molten” (The Solar Nebula. N.d). Over time the earth cooled and the crust was formed. “Much continental crust, the most silica rich and least dense kind, has been produced by 2.5 billion years” (The Solar Nebula. N.d). Over a period of time and a series of volcanic eruptions water vapor was thrown into the atmosphere and eventually condensed to form the oceans. From a spinning cloud of dust the evolutionary process began and the Earth that is inhabited today came into existence according to the nebular hypothesis.

5.Art is a major part of the lives of the past and present first nations people. At the Kwanlin Dun Cultural Centre (a first nations museum) teams must correctly perform a cultural dance. First nations people express themselves through the arts and one way is dance.

Choose one specific lake, river, sea or bay. You will be researching biotic and abiotic factors about that lake ecosystem.

The solid part of the Earth consist of solid rocks and soil. The Earths surface is the geosphere. The hydrosphere makes up all of the water on Earth's surface. The Earth is divided into three layers the crust, mantle, and the core. The crust is very brittle and this is why it was easy for Mount St. Helen to blow it to pieces. Tectonic plates are what glides underneath the underlying asthenosphere. This is what causes mountains to shift or grow. This can affect when volcanoes erupt. Volcanos are located near tectonic plate boundaries, where plates either collide or separate.

The earth was formed by countless collisions of meteors/molten rock which made it a world of fire and molten rock.

Thanks to static electricity ice, dirt, rocks and other grains of solid material slowly began to gather together forming bigger pieces, those pieces formed bigger pieces, having a “snowball” effect. They eventually became big enough to have their own gravitational field which then collected more material, eventually creating a planet. More material meant more mass, which gave the forming planet even more gravity. With tons and tons of material, and gravity pushing it together, intense pressure causes intense heat. This combination of pressure and heat gives the earth its molten interior.

It has been known for well over a century now that the Earth’s core, mantle and the crust make up the basic structure of the Earth. However, there is some controversy over how and when the Earth produced its core, mantle and crust. In this essay, I will first discuss about the formation of the Early Earth and its Moon, then about the methods used to pinpoint the age of the Earth. Other than that, I will also expand on core and mantle formation, as well as the eventual production of the continental crust.

The initial steps of our solar system began with a star known as the sun. By this point, the sun was formed and there was debris floating all throughout the universe. The larger objects that managed to escape the sun’s fury collided with each other and accreted. This means “stellar objects grow in size through collision and sticking together of particles” (Christian, Brown, Benjamin). With accretion the planets and solar system came to be. To be more descriptive, I will focus on the formation of the earth. The Earth is made up of three layers: the core, mantle, and crust. After the accretion process all the elements that bunched up together started to settle into the Earth based on weight. Due to intense heat brought on by the Hadean Era, metals began to melt and brought to the core of the planet because of gravity; this is called chemical differentiation (Christian, Brown, Benjamin) . The heavier elements, like metals, were found in the core while lighter elements like silicates were found in the mantle and crust. This is of essential importance to the making of the hand held radio because it settles materials like metal onto earth. Without metals the radio would be missing key components for its creation. Having it available on Earth gave access to later creations to create the parts of the hand held radio like the

In the beginning, impacts of very large objects were very common, some as big as Mars or half the diameter of Earth. Collision of large bodies orbiting Earth played a role in its initial tilt of spin axis, the length of its day, direction of spin, and the thermal state of the interior. This violent bombardment continued for 3.9 billion years. Final composition of Earth had several crucial structural effects. Enough metal was present early on to allow formation of an iron and nickel rich core that is partially liquid. This enables a magnetic field that deflects some harmful radiation from reaching the surface. Enough radioactive elements are also present in the core to maintain long term heating which drives plate tectonics. At 4.5 billion years ago, Earth separated into different layers: an inner core (made of iron and nickel), a land layer of lower density material, and an early atmosphere of carbon dioxide and steam. At 3.9 billion years ago, surface temperatures dropped to a range where liquid water could be maintained. Liquid water makes up approximately 75% of the planet's surface today which is roughly what it was then. The most important requirement for life as we know it is the presence of liquid water. This is the one substance that can serve as a universal solvent - that is, it can dissolve and transport minerals and

A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. Each biome has it’s own characteristics such as the tundra.

Earth is in fact an intricate planet that has multiple layers of differing compositions. To be exact the earth has four main layers. The uppermost layer is the one humans come in most contact with, the crust. The crust consists of “thin silicate rock material”(Structure of the). Although the crust is not entirely the same. Actually there are two distinct types of crust, oceanic and continental. “The continental crust is made up of mostly rocks similar to granite while the oceanic crust is much denser and made up of a material similar to basalt”(Structure of the, Rose). The second layer is called the mantle. “The mantle is much denser than the crust and contains similar to the crust mostly solid silicate crust”(Structure of the). “As we travel further down the earth we wind up in the outer core. The outer core is a core of molten nickel and iron. Finally there’s the inner core. The inner is a solid metal core made up of nickel and iron”(Structure of the). All these layers functioning together cast out a magnetic

The continental crust consists of igneous and sedimentary rocks. The oceanic crust consists of the same with a substantial layer of sediments above the rock. The crust covers the outer ridged layer of the earth called the lithosphere. The lithosphere is divided into seven main continental plates. These continental plates are constantly moving on a viscous base.
