Geographical Information System.

 tropospheric

INCREASED surface UV leads to increased tropospheric ozone.

 moisture conservation

Mulch is any material that is spread or laid over the surface of the soil as a COVERING. It is used to RETAIN moisture in the soil, suppress weeds, keep the soil cool, and make the garden BED LOOK more attractive. Organic MULCHES also help improve the soil's fertility, as they decompose.

 Molecular oxygen (O₂)

Molecular oxygen (O₂) is not BELIEVED to be RESPONSIBLE for enhancing the EARTH's greenhouse EFFECT.

 SECONDARY SUCCESSION

The FORMATION of a climax community from an abandoned FARM land is a an example of secondary succession.

 BLACK

If the Earth had no ATMOSPHERE then the sky WOULD have LOOKED dark. The original COLOUR of the sky(or space) is black. Just the atmosphere of the Earth gives the colour white, blue and dark blue.

 Ozone

Particulate MATTER consists of soot, flash, dust of various TYPES, fur, HAIR, spores etc. They are classified into settleable and SUSPENDED particulate matter.

 Species

A species is a group of INDIVIDUAL ORGANISMS that interbreed and produce fertile, VIABLE offspring. According to this definition, ONE species is distinguished from ANOTHER when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring.

 Water vapor

Water vapour is CONSIDERED a variable gas in the earth's ATMOSPHERE.

 A way of determining cloud THICKNESS and altitude.

Infrared satellite technology works by sensing the temperature of infrared radiation being emitted into space from the earth and its atmosphere. Basically, all objects (including water, land, and clouds), radiate infrared light. However, our eyes are not "tuned" to see this kind of light, so we don't notice it. WEATHER satellites not only sense this infrared light, but they can also sense the temperature of the infrared emissions.
Visible satellite IMAGES can be thought of as photographs of the earth from space. SINCE they are like a photograph, they are dependent on visible light (BROUGHT by the sun). As a result, visible satellite pictures only work during daylight hours. This is the greatest drawback to using visible imagery. Also, since a visible satellite picture is basically a photograph, thicker clouds (which reflect the most sunlight) show up very bright, while thinner clouds (like cirrus) are hard to distinguish.

 NUCLEAR power

Nuclear power was DEVELOPED after World WAR II.

 Savannah

In SOUTH AMERICA, they're known as PAMPAS. Central Eurasian grasslands are REFERRED to as STEPPES, while African grasslands are savannas.

 Packaging materials

The RESIDENTIAL and Commercial wastes MAINLY CONSIST of packaging materials.

 Floods

Floods is the natural PHENOMENON, caused by an UNLIMITED and UNPRECEDENTED RAINFALL.

 Counterclockwise; inward

In the MIDDLE latitudes of the NORTHERN Hemisphere, SURFACE winds tend to blow Counterclockwise and inward around an area of surface LOW pressure.

 RICHTER SCALE

The INTENSITY of EARTHQUAKE is MEASURED in Richter scale.

 Increase

If the sun suddenly BEGAN emitting more energy, the EARTH's radiative EQUILIBRIUM TEMPERATURE WOULD increase.

 hypotonic, a contractile VACUOLE

Freshwater protozoans REACT to a/an hypotonic environment by REMOVING water through a contractile vacuole.

 HOUSE LIZARD -AUTOTOMY

House lizard - Autotomy

 IUCN

Red DATA book is the document established by IUCN for documenting the RARE and ENDANGERED species of plants, animals, fungi and also a few local species that exist WITHIN a state or country.

 CHINA

The WORLD's BIGGEST GHG EMITTER is China.

 are small solid particles and liquid droplets

Particulate matter contains MICROSCOPIC solids or liquid droplets that are so small that they can be inhaled and cause serious HEALTH problems. Some particles less than 10 MICROMETERS in diameter can get deep into your LUNGS and some may EVEN get into your bloodstream.

 Azotobacter

Azotobacter is a GENUS of usually motile, OVAL or spherical bacteria that form thick-walled cysts and may produce large quantities of capsular slime. They are aerobic, free-living SOIL microbes which play an important role in the nitrogen cycle in nature, binding atmospheric nitrogen, which is inaccessible to plants, and RELEASING it in the form of ammonium IONS into the soil (nitrogen fixation).

 E O Wilson

Biophilia is the term coined by the HARVARD naturalist Dr. Edward O. Wilson to describe what he SAW as HUMANITY's "INNATE TENDENCY to focus on life and lifelike processes," and to be drawn toward nature, to feel an affinity for it, a love, a craving.

 Summer solstice

After the June solstice, the sun FOLLOWS a LOWER and lower path through the sky each day in the Northern Hemisphere until it reaches the point where the length of daylight is about 12 HOURS and eight to NINE minutes in areas that are about 30 degrees north or SOUTH of the equator.

 UV radiations

In terms of potential BIOLOGICAL effects, the non-ionizing PORTION of the spectrum can be subdivided into: The OPTICAL radiation portion, where electron excitation can occur (visible light, infrared light) The portion where the wavelength is smaller than the body. HEATING via induced currents can occur.

 london smog

Hence, the smog that occurs due to LOW temperature i.e. in COLD CLIMATE, and has reducing environment is CLASSICAL smog or London smog. So, the CORRECT answer is 'London smog

 PYROLYSIS

The COMBUSTION of WASTE in the absence of OXYGEN is CALLED Pyrolysis.

 Nitrogen and oxygen

The atmosphere CONTAINS many gases, most in SMALL AMOUNTS, including some pollutants and GREENHOUSE gases. The most abundant gas in the atmosphere is nitrogen, with oxygen second. Argon, an inert gas, is the third most abundant gas in the atmosphere.

 SEA gull

The maximum number of deposition of DDT will occur in phytoplankton crabeelor SEAGULL. DDT is a colourless, odourless and a tasteless CRYSTALLINE CHEMICAL compound, which was ORIGINALLY invented as an insecticide.

 16

The TOTAL number of MAJOR LANGUAGES in India are 16.

 81

The United States GETS 81% of its total energy from OIL, coal, and natural gas, all of which are fossil fuels. We depend on those fuels to heat our HOMES, run our vehicles, power industry and manufacturing, and provide us with electricity.

 DECIBELS

Although the units for sound intensity are technically watts PER meter squared, it is much more COMMON for it to be referred to as decibels, dB. A decibel is a ratio of the observed AMPLITUDE, or intensity level to a reference, which is 0 dB.

 Diarrhoea

Diarrhoea is not CREATED by NOISE POLLUTION.

 Heat ENERGY from the EARTH's INTERIOR

Heat energy from the earth's interior contribute to this heating.

 Salim Ali

Salim Ali, often called 'the bird man of INDIA', was among our best-known ornithologists and CONSERVATIONISTS. His work as scientist, TEACHER and writer introduced millions of Indians to the joys of the NATURAL WORLD.

 ECOLOGY of community

Synecology is a subfield of ecology CONCERNED with the relations between GROUPS of organisms or coexisting BIOLOGICAL COMMUNITIES.

 HELIOPHYTES

Plants which GROW in LIGHT are CALLED Heliophytes.

 INDIRA Gandhi

The BIGGEST award for ENVIRONMENTAL ACTIVITIES in India is GIVEN in the name of Indira Gandhi.

 biomagnification

Biomagnification, also known as BIOAMPLIFICATION or biological MAGNIFICATION, is any concentration of a toxin, such as PESTICIDES, in the tissues of tolerant organisms at successively higher levels in a FOOD CHAIN.

 Autotrophs

Producers are organisms that make their own food; they are also known as autotrophs. They get energy from chemicals or the SUN, and with the help of water, convert that energy into usable energy in the form of SUGAR, or food. The most COMMON EXAMPLE of a producer are plants.

 low moisture content

The microorganisms BREAKDOWN the complex compounds of dead protoplasm of producers and consumers absorb some of the decomposition products and release SIMPLE substances. The slow RATE of decomposition of fallen logs in NATURE is due to their low moisture content The cellulose is in high amount in fallen logs.

 The direction from which the wind is blowing

Wind direction is reported by the direction from which it originates. For example, a NORTHERLY wind blows from the north to the south. Wind direction is usually reported in CARDINAL DIRECTIONS or in AZIMUTH degrees. Wind direction is MEASURED in degrees clockwise from due north.

 LAKES and forests to die

Rainfall that is acidic, possesses elevated H+ ion concentrations, and has been commonly known as ‘acid rain’.
the contribution from SO2 is considerably smaller than during the 1970s, so that currently, oxidised and reduced nitrogen dominate acid deposition. Deposition of reduced nitrogen (N) compounds, e.g.NH4+, can acidify via microbial transformations in the soil and also assimilation in plants LEADING to acidification of the rhizospehere. Other compounds also CONTRIBUTE to acid deposition, e.g. hydrochloric acid (HCl)

 Antarctica

The discovery of the annual depletion of ozone above the ANTARCTIC was first announced in a PAPER by Joe Farman, Brian Gardiner and Jonathan Shanklin which appeared in Nature in MAY 1985. Later, NASA scientists re-analyzed their satellite data and found that the whole of the Antarctic was affected.

 105^o F

At 105^o F the EARTH would be RADIATING ENERGY at the greatest RATE or intensity.

 BIOMASS

Renewable ENERGY RESOURCES are MOSTLY BASED on biomass.

 EVAPORATION

Evaporation is the process by which water CHANGES from a liquid to a gas or vapour. Evaporation is the primary pathway that water moves from the liquid STATE BACK into the water CYCLE as atmospheric water vapour.
