The subtropical climatic zone lies between
-
$0-22^{o}$ latitude
-
$20^{o}-40^{o}$ latitude
-
$40^{o}-60^{o}$ latitude
-
$60^{o}-80^{o}$ latitude
Subtropical climate zone:
Area - between the tropical zone and the temperate zone (25 degree to 40 degree North and South latitude).
Average temperature - 20 to 35 degree Celsius.
Precipitation - Dry, winter humidity and always wet areas.
Vegetation - Semi deciduous or evergreen forests, hardwood forest with winter rain, savannah, pasture land, semi desert, warm temperate moist forests, nemoral deciduous forests.
Which of the following is wrongly matched?
-
Temperate zone - 20-40$^o$ latitude
-
Hypolimnion - thermal stratification in lakes
-
Ozone layer - stratosphere
-
Profundal zone - dark zone

From $23.5^0$N to $66.5^0$N and between $23.5^0$S and $66.5^0$S are the temperate zones, where there are clear spring/summer/fall/winter seasons. The north temperate zone extends from the tropic of cancer to the arctic circle. The south temperate zone extends from the tropic of capricorn to the antarctic circle. Between $23.5^0$S and $23.5^0$N latitude we have the tropics - where high temperatures are the norm, and the sun can beat down from directly overhead once or twice each year.
Tropical region occurs
-
At 2$3^0$ N and 2$3^0$ S
-
Between 2$3^0$ N and 2$3^0$ S
-
Between $0^0$ and 2$3^0$ N
-
Between $0^0$ and 2$3^0$ S
Tropical region occurs at 23$^o$ N and 23$^o$ S. The region is present at the equator. It is limited in latitude by the tropic of cancer in the north and the tropic of capricorn in the south.
If at high altitudes, birds become rare, the plants likely to disappear are
-
Pine
-
Orchids
-
Oak
-
Rhododendrons
Pines seeds are mainly small and winged, and are anemophilous generally, which means that the seeds are dispersed by wind. However, some seeds are larger and they have only a vestigial wing and are needed to be dispersed by a bird. Thus, If at high altitudes, birds become rare, the plants likely to disappear are Pine plants. Oaks are not generally found at such high altitudes.
