The offer four energy learning zones for kids each one with its own on-line childrens quiz that teach us and test us about how energy impacts on every aspect of our life. A chemical industry is not a cause of: a Air pollution b Noise pollution c Water pollution d Nuclear pollution 7. The desert among the following which is not a cold desert is: a Golbi desert b Patagonian desert c Atacama desert d Majava desert 37. What are the measures to control odour pollution? The maximum number of individuals that can be supported by a given environment is called a Biotic potential b Carrying capacity c Environmental resistance d Population size 19. This, however, has only minor effects on climate change.
Objective of environmental studies is to Create environmental ethics that foster awareness about the ecological inter - dependence of economic, social and political factors in a human community and the environment Acquiring skills to help the concerned individuals in identifying and solving environmental problems Raise consciousness about environmental conditions All of the above. » Learn more about the. The rise in population and demand for space and basic amenities has led to overutilization of the available resources. Sustainable development will not aim at: a Social economic development which optimise the economic and societal benefits available in the present, without spoiling the likely potential for similar benefits in the future b Reasonable and equitable distributed level of economic well being that can be perpetuated continually c Development that meets the need of the present without compromising the ability of future generation to meet their own needs d Maximising the present day benefits through increased resource consumption 17. Food chain starts with a Producer b Herbivores c Carnivores d Omnivores 25.
The principal objectives of waste water treatment are: 1. What are the ways to conserve forest? What is the m eaning and objective of environmental education? Global sea level has risen approximately 7. » Learn more about the. » Learn more about and , and the. Above 10-12 km, it is nearly absent.
In other words any sound may be noise if circumstances cause it to be disturbing. Plants, oceans, and soils release and absorb large quantities of carbon dioxide as a part of the Earth's natural carbon cycle. What is one of the main goals of industrial ecology? Give an account of the classification of ecology. Geological changes have caused long-term bio-diversity trends, since it is largely dependent on relative fragmentation of land-masses. A solution to the word search is included too. Describe specific types of evidence people should look for in their own ecosystem to determine whether humans are changing the local environment. But, if the area is replanted, erosion can be checked.
Our second printable below focusses on the climate change caused by global warming. Use it as a classroom or home-school worksheet or maybe as an an environmental quiz sheet. Then, the similar averages are compared when it is found that the mean temperature for one year is greater than that in the previous year; we know that a change has occurred. It was only since the 1950s that nations of the world started conservation and wise utilization of their natural resources — such as water, soil, fuel, flora and fauna. Developed countries have made considerable progress in the field of protection and conservation of the environment on a-long-term basis. It becomes repulsive when the urea content normally about 0.
Let us take for example the Monsoon Rains in West Bengal. When you have completed the practice exam, a green submit button will appear. The questions and answers often generate further discussion which is a perfect prompt for further research. The free quiz is a glimpse at how we all impact upon on our planet as it assesses your consumption of energy, food, housing, goods, etc. Since photosynthesis is essential for the existence of organic life, we find that life is confined to only those regions where solar energy can be captured for photosynthesis. Supporting capacity and assimilative capacity are the components of a Carrying capacity b Holding capacity c Containing capacity d Capturing capacity 20.
The left overs left behind in the soil as irrigated water forfarming evaporates, which makes the soil water have a higherosmotic content for the plants. Finally, we have realised that forests should not only be preserved for maintaining timber supplies, but also for checking soil erosion, flood, safeguarding water supplies, and for providing recreational facilities. Therefore, waste water is a complex mixture of natural inorganic and organic materials mixed with man-made substances. Which of the following conceptual components of the environment are effective transporters of matter? The is a free on-line lifestyle survey that estimates your 'ecological footprint'. If they are buried, the poisons may kill the plants growing above or may be leached out into ground water and find their way into public water supplies or rivers where they harm wildlife. Proper vigilance, inspection and timely maintenance can reduce unaccounted loss of water to a large extent.
This sheet compliments our global warming worksheet above and easily stimulates further discussion. The primary producers in a forest ecosystem are: a Chlorophyll containing trees and plants b Herbivores c Carnivores d Bacteria and other micro-organism 36. For example, a sea level rise of two feet, without any changes in storms, would more than triple the frequency of dangerous coastal flooding throughout most of the northeast United States. Many of the actions that we can take to address climate change will have other benefits, such as cleaner, healthier air. » Learn more about the. The weak or diseased species, or the mature species, that are occupying space uselessly, must be removed. Models that account only for the effects of natural processes are not able to explain the warming observed over the past century.
Second, modeling studies show that when human influences are removed from the equation, the global climate would have actually cooled slightly over the past half century. The mechanism of plate-tectonics influences sea-level change, volcanic and mountain building activities, continental drift and true polar wander. Describe what you can do as an individual to limit your impact. . Right from the day they are born, till the moment they breathe their last, human beings experience a variety of change. List the following information for how each impact affects ecosystems: a. If the furrows ran downhill, heavy rain could form channels and carry the soil away.
The osmogenic molecules smell enter the nasal cavity through the nostrils. Energy flow in an ecosystem is always: a Unidirectional b Cyclic c Reversible d Multi-directional 35. Natural Sources — i Dust: Soil erosion, volcanic eruption, landslides, storms, earthquakes. Their numbers diminish and so do the numbers of mites which depend on them for food. Which of the following is a possible producer in an ecosystem? In rural communities houses do not have water connections, and supply is through hand pumps, wells, tanks etc.
