Central Asian Steppes.This statement is about the Central Asian Steppes. It is also sometimes referred to as Middle Asia, and, colloquially, "the 'stans" (as the five countries generally considered to be within the region all have names ending with the Persian suffix "-stan", meaning "land of") & is within the scope of the wider Eurasian continent. Central Asia is the core region of the Asian continent & stretches from the Caspian Sea in the west to China in the east & from Afghanistan in the south to Russia in the north. Central Asia has historically been closely tied to its nomadic peoples & the Silk Road. Central Asia has the following geographic extremes: world's northernmost desert (sand dunes) , at Buurug Deliin Els, Mongolia; the Northern Hemisphere's southernmost permafrost, at Erdenetsogt sum, Mongolia; world's shortest distance between non-frozen desert & permafrost: 770 km; & the Eurasian pole of inaccessibility. A majority of the people earn a living by herding livestock. Industrial activity centers in the region's cities.

(C) Andaman and Nicobar
4"Tsunami" is the name given to which of the following -?
. A tsunami or tidal wave, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a big volume of water, generally in an ocean or a big lake. Unlike normal ocean waves which are generated by wind, or tides which are generated by the gravitational pull of the Moon & Sun, a tsunami is generated by the displacement
Waterfall. Yosemite Falls is the highest measured waterfall in North America. Situated in Yosemite National Park in the Sierra Nevada of California in the United States, it is a major attraction in the park, especially in late spring when the water flow is at its peak.
6_______ forms the western boundary of the Indian sub-continent.?
Crust. The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core & the inner core. The crust ranges from 5-70 km in depth & is the outermost layer. Out of them, the mantle is the thickest layer (extends from where the crust ends to about 2,890 km) , while the crust is the thinnest layer.

121. Cirrus ------------- A. feather 2. Cumulus ---------- B. Heap 3. Stratus ------------ C. Layer type 4. Nimbus ------------ D. Rain cloud?
it determines the Indian standard time. Indian Standard Time (IST) is the time observed throughout India & Sri Lanka, with a time offset of UTC+05:30. In military & aviation time IST is designated E* ("EchoStar") . India does not observe Daylight Saving Time (DST) or other seasonal adjustments. Indian Standard Time is calculated on the basis of 82.5° E longitude, from a clock tower in Mirzapur (25.15°N 82.58°E) (near Allahabad in the state of Uttar Pradesh) which is nearly on the corresponding longitude reference line
the equator from south to north. A traveler crossing the International Date Line eastbound subtracts one day, or 24 hours, so that the calendar date to the west of the line is repeated. The International Date Line is necessary to have a fixed, albeit arbitrary, boundary on the globe where the calendar date advances in the westbound direction. Crossing the IDL westbound results in 24 hours being added, advancing the calendar date by one day.
throws water & steam at regular intervals. A geyser is a spring characterized by intermittent discharge of water ejected turbulently & accompanied by a vapour phase (steam) . The word geyser comes from Geysir, the name of an erupting spring at Haukadalur, Iceland; that name, in turn, comes from the Icelandic verb geysa, "to gush", the verb itself from Old Norse.
18A group of inter-attached islands is known as----------.?
Archipelago. An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. Indonesia, Japan, the Philippines, New Zealand, the Maldives, the Bahamas, Greece, Hawaii, & the Azores are examples of well-known archipelagos.
19A high growth rate of population is characterised by?
high birth & low death rates. Population growth is the change in a population over time, & can be quantified as the change in the number of individuals of any species in a population using "per unit time" for measurement. High birth & low death rates add to the population base considerably as while the base remains intact, the erosion due to deaths is hampered.
20A landscape which is caused due to the fissure in the earth along which one side has moved down with reference to the other is known as?
Rift Valley. A rift valley is a linear-shaped lowland caused due to the fissure in the earth along which one side moves down with reference to the other. A rift valley is formed on a divergent plate boundary, a crustal extension, a spreading apart of the surface. It is commonly seen between several highlands or mountain ranges created by the action of a geologic rift or fault.
21A level of atmosphere which is composed partly of electrons & positive ions is called?
Ionosphere.Ionosphere is composed partly of electrons & positive ions. This layer is also called thermosphere as its temperature rises with height. It is a region of Earth's upper atmosphere, from about 60 km to 1,000 km altitude, that is ionized by solar radiation.
22A major benefit to crop rotation would be?
(A) Several different crops produced in the same year
(B) Nitrogen is put into the soil; which is needed for plants
(C) Requires less manual labor
(D) Farmers can replenish the soild and improve agricultural productivity
23A meteor is?
(A) a piece of mater which has entered the earth's atmosphere from outer space
Meteor is a small celestial body which has entered the earth's atmosphere by the gravitational force of earth, when they pass close to it. Meteors typically occurs in the mesosphere, and most range in altitude from 75 km to 100 km.
24A new type of El Nino called El Nino Modoki appeared in the news. In this context, consider the following statements: 1. Normal El Nino forms in the Central Pacific Ocean whereas El Nino Modoki forms in Eastern Pacific Ocean 2. Normal El Nino results in diminished hurricanes in the Atlantic Ocean but El Nino Modoki results in a greater number of hurricanes with greater frequency. Which of the statements given above is/are right?
Estuary.Estuaries form a transition zone between river environments & ocean environments & are subject to both marine influences, such as tides, waves, & the influx of saline water; & riverine influences, such as flows of fresh water & sediment. The inflow of both seawater & freshwater provide high levels of nutrients in both the water column & sediment, making estuaries among the most productive natural habitats in the world.
26A rift valley is formed mainly due to:?
(A) forces of tension in the earth's crust
(B) the subsidence of the floor of a river valley
(C) the valley formed after the formation of fold mountains
(D) the deepening of a valley by ice action
27A semi enclosed coastal body of water which has a free connection with the open sea is called?
Estuary.An estuary is a semi-enclosed coastal body of water which has a free connection with the open sea & within which sea water is measurably diluted with fresh water derived from land drainage. They are subject both to marine & riverine influences. Estuaries form a transition zone between river environments & maritime environments.
28A special type of well in which water rises automatically under the pressure of a column of water to the ground surface through a hole is known as?
Artisian well. An artesian well is a pumpless water source that uses pipes to allow underground water that is under pressure to rise to the surface. In addition, the water has been naturally filtered as it passes through porous rock as it seeps into the Earth to reach the aquifer, which is the underground water source. This type of well seems to defy gravity as the pressure that builds up between layers of rock gets relieved when the water finds a path to the open air. For centuries, people have drilled artesian wells to drink filtered water that doesn't need to be manually or mechanically hauled up from the depths.
Lagoon.Lagoon is a shallow stretch of water which is partly or completely separated from the sea by a narrow strip of land. Lagoons are common coastal features around many parts of the world. In the case of coral reef, it is a channel of sea water between the reef & the main land.
