 GHGS

Global warming is CAUSED by GHGs(GREEN house GASES).

Nearly all wild LIONS LIVE in sub-Saharan Africa, but one small population of Asiatic lions exists in India's Gir Forest. Asiatic lions and AFRICAN lions are subspecies of the same species. Asiatic lions once PROWLED from the MIDDLE East to India.

 green revolution

The dramatic increase in AGRICULTURAL production that have been MADE possible by high YIELD miracle crops are CALLED the green revolution.

 Pressure

Pressure ALWAYS DECREASES as we CLIMB UPWARD in the ATMOSPHERE.

 fresh WATER ECOSYSTEM

The PYRAMID of BIOMASS is inverted in fresh water ecosystem.

 bioremediation of CONTAMINATED SOILS

Trichoderma harzianum has PROVED a USEFUL microorganism for bioremediation of contaminated soils.

All the above

 34641

The WATER management ACT is COMPLEMENTED by the WASTE water charges act at 34641.

 Infrared radiation and is invisible

Most of the radiation emitted by the HUMAN body is mainly at the wavelength of 12 micron. The wavelength of infrared radiation is between 0.75 to 1000 micron (1 micron = 10^-6metres). Hence , the MAJORITY of radiation emitted by human bodies LIE in the infrared region.

 Decreases

When the air temperature is equal to the dew point temperature, the air is at the SATURATION point and the relative humidity is 100%. The GREATER the DIFFERENCE between air temperature and dewpoint, the lower is the relative humidity.

 ALWAYS INVERTED

The PYRAMID of number of a PARASITIC food chain in FOREST ecosystem is always inverted.

 FOOD WEB

The INTERLOCKING pattern of various food CHAINS is referred as food web.

 ENDEMISM

Hot SPOTS are REGIONS of HIGH endemism.

 Continent

Continent has the least similarity when comparing TWO examples of the same biome LOCATED in DIFFERENT parts of the world.

 DECREASE as the AIR BECOMES DRIER

Decrease as the air becomes drier.

 TREES

A RENEWABLE SOURCE of ENERGY is trees.

 Biomagnification

HIGHER the trophic level an organism occupies in the FOOD chain higher will be the accumulation of non-biodegradable PESTICIDE RESIDUES. This phenomenon is called as biomagnification.

 environmental studies

Environmental studies is an integration of several subjects that INCLUDE both SCIENCE and SOCIAL studies.

 Circulation of HEAT by the atmosphere and oceans

A radiation inversion is most commonly observed: just above the ground. Although the POLAR regions radiate away more heat energy than they receive by insolation in the COURSE of a year, they are prevented from becoming PROGRESSIVELY COLDER each year by: the circulation of heat by the atmosphere and the oceans.

 Pyramid of number

This deals with the relationship between the NUMBERS of primary PRODUCERS and consumers of different levels. It is a graphical representation of the total number of individuals of different SPECIES, belonging to each TROPHIC level in an ecosystem.

 THIRUVANANTHAPURAM

Agastyamalai BIOSPHERE RESERVE is in Thiruvananthapuram.

 In the afternoon between 3 and 5 PM

In most areas, the warmest time of the DAY about 5 FEET above the ground occurs: in the afternoon between 3 and 5 PM.

 PSAMMOSERE

Succession INITIATED on large SAND DEPOSITS or DESERTS is called Psammosere.

 Ecosystem

Biotic components are the living things that shape an ecosystem. Examples of biotic components INCLUDE animals, plants, FUNGI, and BACTERIA. Abiotic components are non-living components that influence an ecosystem. Examples of abiotic FACTORS are temperature, air currents, and minerals.

 Tamilnadu

The constitution of the Calcutta bench was followed by another in Chennai. On September 2,1996, while passing an INTERIM order in the Tamil Nadu tanneries CASE, a full bench of the SC comprising Justices Kuldip SINGH, Falzan-uddin and K Venkataswami asked the chief justice of the Chennai High Court to constitute a special GREEN bench to deal with environmenal matters - including the tanneries case - in that STATE.

 Producing COMPOST manure

Vermicompost (vermi-compost, VERMICULTURE) is the product of the decomposition PROCESS using VARIOUS species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and VERMICAST.

 Nilgiri Tahr

The PARK holds the maximum viable population of the endangered Nilgiri Tahr INCLUDING other little KNOWN FAUNA Nilgiri MARTEN, ruddy mongoose, small clawed otter, dusky striped squirrel etc.

 Carbon dioxide

Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our PLANET would be inhospitably cold. However, a gradual increase in CO 2 concentrations in Earth's atmosphere is helping to drive global warming, threatening to disrupt our planet's climate as average global TEMPERATURES gradually rise.

 Gravity

Our atmosphere is a mixture of gases that surround Earth. It is kept in PLACE by the pull of Earth's gravity. If Earth was a much smaller planet, like MERCURY or PLUTO, its gravity WOULD be to WEAK to hold a large atmosphere.

 1 week

The total mass of water vapour stored in the atmosphere at any MOMENT is about 1 week of the WORLD's SUPPLY of precipitation.

 LANDSLIDE

Slip erosion is also know as landslide. When earthquakes occur on areas with STEEP slopes, many TIMES the soil slips causing LANDSLIDES.

 JET PLANES

The SOURCE of aerosol in upper atmosphere is jet planes.

 Genetically FIXED

Ecotype is a TYPE of SPECIES in which environmentally INDUCED variations are genetically fixed.

 REMAIN the same

As the AIR TEMPERATURE INCREASES, with no addition of water VAPOR to the air, the dew point will remain the same.

 Solar FLUX

The amount of solar radiation REACHING the SURFACE of the earth is called Solar flux.

 darkening of skin due to industries

Industrial melanism REFERS to the evolution of DARK body colours in animal species that live in HABITATS blackened by industrial soot. The phenomenon has been documented in numerous species that hide from predators by blending in with their BACKGROUNDS. Peppered moths provide one example.

 LAKE

A lake is formed due to the collection of WATER in a natural basis or DEPRESSION in a MOUNTAINOUS AREA or in plains.

 kidney damage

Lead exposure can have serious CONSEQUENCES for the health of children. At high levels of exposure, lead ATTACKS the brain and CENTRAL nervous system to cause coma, convulsions and even death. Children who survive severe lead poisoning may be LEFT with mental RETARDATION and behavioural disorders.

 All the above

All the above CONTRIBUTE to DISPLACEMENT.

 Some SPECIES will be extincted

Some species will be extincted.

 Observing CHANGES in SATELLITE orbits

Scientists are able to DETERMINE the AIR temperature in the thermosphere by observing changes in satellite orbits.

 Rain gauge

A rain gauge (also known as an udometer, pluviometer, or an ombrometer) is an instrument used by meteorologists and hydrologists to gather and MEASURE the amount of LIQUID PRECIPITATION over an area in a predefined period of TIME.

 ULTRAVIOLET, visible, and infrared RADIATION

Solar radiation REACHES the EARTH's SURFACE as ultraviolet, visible, and infrared radiation.

 CHAPARRALS

Average TOTAL RAINFALL is 100 - 150 CM in chaparrals, located in Australia, South America and Africa.

 Water vapour

Volcanoes ALSO give off greenhouse gases. The most abundant gas released from volcanic eruptions is water vapour. Other emitted gases include CARBON dioxide (CO2), sulfur dioxide (SO2), hydrogen sulfide (H2S), carbon monoxide (CO), hydrogen CHLORIDE (HCl), and hydrogen fluoride (HF).

 September 16

In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, COMMEMORATING the DATE of the SIGNING, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer.

Chlorofluorocarbons (CFCS) and other halogenated ozone depleting substances (ODS) are mainly RESPONSIBLE for man-made chemical ozone DEPLETION. The TOTAL amount of effective halogens (chlorine and bromine) in the stratosphere can be CALCULATED and are known as the equivalent effective stratospheric chlorine (EESC).
