There are 3 different main cycles. There 's the nitrogen cycle , water cycle , carbon cycle. They work together by carrying away waste and restoring the ecosystem with nutrients that are necessary to sustain life. These three cycles help the world function to produce air, water , and nutrients. If any of these three cycles were to become unbalanced , the effects on the ecosystem would be catastrophic. The Water Cycle is the cycle of process by which water circulates between the earth 's ocean , atmosphere , and land , involving precipitation as rain and snow, drainage, in streams and rivers , and return to the atmosphere by evaporation and transpiration. The earth has a limited amount of water. The water found above and below …show more content…
This cycle is critical to ecosystems as it is part of the food chain. All living things are made of carbon (compounds like proteins, fats, nucleic acids, and carbohydrates) and it is recycled in various ways. The compound formula for the carbon cycle is C6HI206+602→ 6H2=6C02+energy. There are 5 parts to the carbon cycle. There 's combustion which is when carbon is released into the atmosphere when burning fossil fuels-- heating homes, driving cars.photosynthesis is when carbon is absorbed by producers/ autotrophs- plants that make their own food through photosynthesis. Consumption is when carbon compounds are passed to herbivores when they feed on photosynthetic plants. These compounds are then passed up the food chain when the herbivores are eaten. Respiration is a byproduct of consumptions is energy creation and carbon dioxide waste. Carbon dioxide enters the atmosphere through cellular respiration and can then be used by plants during photosynthesis. Decomposition is when carbon dioxide is given off when organisms die. Decomposers break down the dead matter and carbon compounds are released into the soil. These compounds can sometimes turn into fossil fuels which
The rock cycle is extremely helpful and useful for scientists all over the world. These scientists use physical geology, which carefully focuses on how rocks form into other rocks (Doc. 2). Also, through the rock cycle, three types of rocks form, which are called igneous rock, sedimentary rock, and metamorphic rock (Doc. 1). The rock cycle is much like the water cycle, but it takes millions of years for a rock to form, wear down, and form again. Also, scientists need the rock cycle to watch how the rocks form overtime (OI).
In the book Stiff, by Mary Roach, she shares her experiences in learning about the different disposal of bodies. The book explains that beyond a natural burial and cremation, bodies can also be disintegrated into the Earth or even turned into a tree. Although there are many alternative methods for the disposal of a body, cremation has less environmental concerns, is quicker, and is not as much money compared to most methods; therefore cremation is the most reasonable disposal of a body. Stiff explores different ways to dispose bodies such as tissue digestion, but compared to cremation, it seems to be more environmentally concerning.
Water is constantly moving and changing through a process called the water cycle. The sun heats bodies of water on earth causing evaporation. After the air currents carry the water vapor into the air, it condenses and forms clouds. When cloud particles grow and collide they form precipitation; this
When the sunlight was blocked from the Earth, the producers would die. The sun is their source of food and it sustains them. This would lead to a collapse in the consumers, because their source of sustainment then is gone. Both of these deaths would result in a large amount of food for the decomposers. Eventually, after all the producers and consumers are gone, the decomposers would die off.
The greenhouse gases in the atmosphere absorb some of this energy, while the rest is emitted back into space, as a naturally occurring cycle that repeats daily which is needed to keep the earth 's surface warm. The green house gases that humans are adding to the atmosphere are like the steroids of the climate system. The problem is that humans are producing far too much greenhouse gases due to increased human activities that demand the use of energy, which has led to emissions and an increase in greenhouse gases. An increase in these greenhouse gases in the atmosphere means more heat is trapped in the atmosphere, and less is emitted into space, which essentially warms up the average temperature of the earth. A small increase in temperature creates major effects to our environment, which is seen in the idea of climate change.
The water cycle is over a thousand year old process that recycles water. During the water cycle, a form of precipitation hits the ground. Then the water goes in one of four paths before it is evaporated, condensed, and repeated. One
Burning fossil fuels is one of the main culprits that causes climate change because it releases gases into the atmosphere that trap in heat and create the greenhouse effect. According to Klaus S. Lackner, the director of the Center for Negative Carbon Emissions and a professor in School of Sustainable Engineering at Arizona State University,”Dumping carbon dioxide and other greenhouses gases into the air raises their concentrations in the atmosphere and causes gradual warming.” This gradual warming is causing many horrific effects
Carbonic acid, then decomposes and creates water plus carbon dioxide. The water and carbon dioxide are incorporated because of temperature. Temperature is the measure of the average heat or thermal
By releasing this gas into the air the natural greenhouse gases increase and cause many effects to happen. Carbon dioxide is also caused by removing natural resources from the land for agriculture. When the Earth starts to warm many other things do to, the ocean will become more acidic and glaciers might partially melt. If the oceans become acidic, fish and other sea creatures will have an unlivable environment. If glaciers start to melt arctic animals that rely on the ice may start to become extinct.

1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
Polar ice caps are melting, sea level is rising, wet places are drying, cold places are warmer, all of these things are caused by Global Warming. What is Global Warming? you might ask. Well Global Warming is a slow rising of the earth’s overall temperature. This means that it isn’t a drastic change and the world’s climate is getting heated up in a week.
With deforestation being one of these roles because when we chop down these trees and plants of where animals habitats our it also releases a lot of carbon dioxide into the air. And if you didn’t know forests are major carbon storage centers, when deforestation happens all the carbon dioxide that is stored in these forests; is released back into the atmosphere. Deforestation not only contributes to changes in the climate, it also causes localized changes in the weather. Trees transpire, or release water into the atmosphere, during photosynthesis. This water replenishes clouds and maintains rainfall.
Balance of natural processes like pollution is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life. •
INTRODUCTION Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth 's streams, lakes, and oceans, and the fluids of most living organisms. Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world.
