i. There are different types of human activities which are directly attributed to the environmental disasters, which includes- acid rain, acidification of oceans, change in the climate, deforestation, depletion of an ozone layer, disposal of hazardous wastes, global warming, overpopulation, pollutions, etc. Image Guidelines 5. It is a key ingredient of urban smog. 2. The atmosphere is divided into five layers.

Horizontal datum are used for describing a point on the earth’s surface, in latitude and longitude or another coordinate system. Stay tuned with BYJU’S to learn more about Environment, Environmental Issues, Ecosystem, Components of the Environment, and other related topics @ BYJU’S Biology.

It’s very nice to read your article. It is the medium for all the reaction and physiological processes in the body. Image Courtesy : epa.gov/airtrends/2010/graphics/Figure7.gif. Vertical datum measure elevations or depths. Weather occurs in this layer. The lithosphere consists of upper mantle and the crust. Also refer: Biotic and Abiotic components. It can be formed by rotating an ellipse about its minor axis, forming an equator with the end points of the major axis. Of them, oxygen is the key for the body as it helps in the generation of energy from the food consumed with the help of mitochondria.

But there is a drastic environment change due to global warming, excessive pollution, industrialization, etc. One experiences peace of mind, low disturbance in mood in such places. A small change in energy can cause a large change in temperature. Why should we conserve biodiversity short answer? The ozone molecules absorb dangerous kinds of sunlight, which heats the air around them. We obtain carbohydrates, fats, proteins from plants. 5. Life is chemis… Before explaining the chemistry that is taking place in these segments one by one, a brief out line about their importance will be discussed.

Hi, this is useful for my intro guidance in Dissertation. The zone making end of this temperature profile is the mesopause.

The environment plays an important role in the existence of life on the planet earth. However, there are a multitude of ways in which we help the environment as well. For shelter: The required building material including furniture is obtained from the environment around. I like to believe that people who do not care about the environment, simply do not understand how important it to all of us and that it does not affect them directly, These are my reasons you should be concerned about the environment. Plagiarism Prevention 4.

While both oxygen and ozone together absorb 95 to 99.9% of the Sun’s ultraviolet radiation, only ozone effectively absorbs the most energetic ultraviolet light, known as UV-C and UV-B. Hence we see many educational institutes and research institutes are built amidst the environment away from the noisy city. From animals, we obtain meat (protein), milk, eggs (birds), honey (bees). Image Courtesy : pansy.eps.s.u-tokyo.ac.jp/images/Katabatic-e.jpg. This ultraviolet light can cause biological damage like skin cancer, tissue damage to eyes and plant tissue damage. Within each ecosystems there are dynamic inter relationships between living forms and their physical environment. A person sitting in an office or closed room is prone to more stress than the one working in an open environment like farms, seashores, etc. The protective role of the ozone layer in the upper atmosphere is so vital that scientists believe life on land probably would not have evolved – and could not exist today – without it. The mesosphere is on top of the stratosphere. Scientists call the ionosphere an extension of the thermosphere. The thermosphere is a layer with auroras.

Oblate spheroids stand in contrast to spheroids.

The major problem with global water supply is its non-uniform distribution, since people in areas with low precipitation often consume more than people in regions with more rainfall.

The ozone layer filters out the sun’s harmful rays. Humans, though often unintentionally, have the most detrimental impact on the environment. When enough ozone molecules are present, it forms a pale blue gas. Prohibited Content 3. For food: Food materials are obtained from plants, animals and natural sources. Stress-free : A healthy environment is good for a stress-free life.

Even though it is such a small part, it is extremely important! So we need to conserve soil for a better environment. Required fields are marked *. Prevent Soil erosion: Soil erosion is an everyday natural activity happening due to winds and floods. The atmosphere transports water from ocean to land. Better breath: All living things breathe air for survival.

The crust is the earth’s outer skin that is accessible to human. iv. Scientists detected the developing problem, and collected the evidence that convinced governments around the world to take action. The atmosphere surrounds Earth and protects us by blocking out dangerous rays from the sun. The atmosphere is a mixture of gases that becomes thinner until it gradually reaches space. Better rainfall: Rainfall is one of the steps of the water cycle on the earth. That means the Sun’s energy is so strong at this level, that it breaks apart molecules. Image Courtesy : ieied.co.uk/images/products/03-PS03-7/hydrosphere_big.jpg. Further, it is a great natural resource for many medicines, metals, chemicals, etc. The earth is divided in to layers as shown in figure-1.3. I also share it. vi. Image Courtesy : portfolio.kelsocartography.com/albums/ng-supplements/biosphere_FINAL.jpg. For furniture: Though we have plastic and artificially made furniture, nothing can replace furniture from an environment like wood, porcelain, china clay, etc. Disclaimer 9. The troposphere is the first layer above the surface. so it is good for health due to abundant fresh air and low toxins and irritants.

When the sun is active, the thermosphere can heat up to 1,500° C or higher!

Image Courtesy : artinaid.com/wp-content/uploads/2013/04/Noctilucent-cloud.jpg. Ozone is concentrated around an altitude of 25 kilometres. As a general definition, altitude is a distance measurement, usually in the vertical or “up” direction, between a reference datum and a point or object. An equator is the intersection of a sphere’s surface with the plane perpendicular to the sphere’s axis of rotation and containing the sphere’s centre of mass. So below we will see the importance of the environment for various roles in life. About 90% of the ozone in the Earth’s atmosphere is found in the region called the stratosphere. It extends up to a mean altitude of 50km. Image Courtesy : dlr.de/pf/Portaldata/6/Resources/images/abt_ep/atm_earth.jpeg. Many epidemic diseases spread fast in such places. For medicine: We obtain many medicines from nature like from medicinal plants, animals (cod liver oil), etc. Importance of Education in Life & Society, Cells in the Human Body | 14 Types with Examples and Functions, Organs of the body | Their Locations and Internal Functions, 14 Uses of Plants & their Importance to Humans & Nature, 10 Types of Chromatography | Based on Different Techniques & Methods, Grammarly Premium Review | A Complete Writing Assistant, Types of Pollution | Their Causes and extent of Damage, 9 Different Types of Spectroscopy Techniques & their Uses, 15 Secreting Organs in Human Body | Their ListLocations & Functions, 6 Types of birds | Scientific Classification with Characters & Pictures, 5 Special Sense Organs | Their Location and Functions in the Body. Most of the weather occurs in the first layer. Some of the oxygen has changed over time to ozone.

The soil is useful for the growth of plants which are again a source of food to the animals around. Environment … Without it, there can be no life on earth. An oblate spheroid is a rotationally symmetric ellipsoid having a polar axis shorter than the diameter of the equatorial circle whose plane bisects it. Content Guidelines 2.

In the stratosphere, we find the “good” ozone that protects life on Earth from the harmful effects of the Sun’s ultraviolet rays. It protects the earth from the hostile environment of outer space. Temperatures in the ionosphere just keep getting hotter as you go up! Humanity's entire life support system depends on the well-being of all the environmental factors. Ozone forms a kind of layer in the stratosphere, where it is more concentrated than anywhere else.

It includes deserts, forests, grasslands, lakes, mountains, ponds, rivers, oceans, etc. Altitude or height is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, and more). The environment assists in the purification of air from the … An Environment is everything that is around us, which includes both living and nonliving things such as soil, water, animals and plants, which adapt themselves to their surroundings. The biosphere refers to the realm of living organisms and their interactions with the environment (VIZ: atmosphere, hydrosphere and lithosphere). The word Environment is derived from the French word “Environ” which meaning “surrounding.” An ecosystem refers to all the living and the non-living things present in the environment and it is a foundation of the Biosphere, which determines the health of the entire planet earth. The atmosphere is divided into five layers depending on how temperature changes with height. The atmosphere reaches its coldest temperature of around -90°C in the mesosphere. Many jet aircrafts fly in the stratosphere because it is very stable. It is also where the space shuttle orbits. 4. Image Courtesy : sess.stanford.edu/sites/default/files/images/LightningIono.png. Ozone has the same chemical structure whether it is found in the stratosphere or the troposphere. In simpler language, the Equator is an imaginary line on the Earth’s surface equidistant from the North Pole and South Pole that divides the Earth into a Northern Hemisphere and a Southern Hemisphere. The Earth’s thermosphere also includes the region of the atmosphere called the ionosphere. Earth is a home for different living species and we all are depended on the environment for food, air, water, and other needs. Natural ecosystem – It is a naturally produced biological environment found in nature. So we need to safeguard the environment in terms of pollution and disposal of garbage. Your email address will not be published.

The average global temperature is about 17 °C. The extent of the use of available fresh water for various purposes is shown in the following figure -1.2. So there ends up being electrons floating around and molecules which have lost or gained electrons. The capitalized term Equator refers to the Earth’s equator. Hence, even scientists are working on only Mars to create life on it as it has some suitable environment.
