  2. specific region

  3. natural region

  4. geographical region
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Monsoon, Savanna, and Equatorial regions are classified as natural regions because they are defined by natural climatic and environmental factors (rainfall patterns, temperature, vegetation) rather than political, economic, or genetic boundaries. Natural regions are areas with similar physical characteristics.

B Correct answer
Explanation

Sunderban (delta), Damodar Valley (river valley), Ruhr Basin (industrial basin), and Bhabar Region (foothill zone) are examples of morphology regions. Morphology regions are areas classified by their surface form, structure, and development characteristics, combining physical and human features rather than single aspect or purely natural divisions.

Multiple choice

Relief, climate, vegetation and soils are the bases of division of

  1. geographical region

  2. natural region

  3. uniform region

  4. specific region
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural regions are areas with similar physical characteristics like relief, climate, vegetation, and soils. These four natural features form the basis of geographical regionalization, helping geographers classify areas with comparable environmental conditions into distinct natural regions.

Multiple choice

The Savannahs are found generally in _______.

Directions: Answer the given question based on the following passage:

Central and South America have some of the world’s most unique species of wildlife. Perhaps, some are more familiar than others. Central and South America has many different groups of species, which include: mammals, birds, reptiles, amphibians, fish, and insects. These groups of animals need to live in specific types of climates and habitats in order to ensure their survivorship.

South America is the home to some of the strangest, some of the loveliest and some of the most horrifying animals in the world. There can be few creatures more improbable than the sloth which spends its life in a permanent state of mute slow motion, hanging upside down in the tall forest trees: few more bizarre than the giant ant eater of the Savannahs, its tail enlarged into a shaggy banner and its jaws elongated into a curved and toothless tube.  On the other hand, beautiful birds are so common as to become almost unremarkable. Gaudy macaws flap through the forest, their splendid plumage contrasting incongruously with their harsh cries; and humming–birds, like tiny jewels, flit from flower to flower sipping nectar, their iridescent feathers flashing the colors of the rainbow as they fly.

The Amazonian rain forest, in Brazil alone, is the largest rain forest in the world. Many species of mammals, reptiles, amphibians, insects, and birds occupy the canopy of this magnificent rain forest. The iguana lives in the trees high above from the ground. It has flattened sides and a long, strong tail, which gives it balance and stability when it leaps. It also has clawed feet, which allows the iguana to grip branches.

The poison dart frog is a tree frog that secretes poison when it gets attacked. Even a small amount of the toxin can be lethal to humans. Today, South American Indians use the poison to tip their arrowheads before hunting.

Many of the South American animals inspire the fascination which comes from revulsion.  Shoals of cannibal fish infest the rivers waiting to rip the flesh from any animal which tumbles among them, and vampire bats, a legend in Europe but a grim reality in South America, fly out at night from their roosts in the forests to suck blood from cows and men.

  1. tropical regions

  2. tundra

  3. mediterranean regions

  4. deserts

A Correct answer
Explanation

Wet temperate forests are found at elevations between 1000 to 2000 metres above sea level in India. These forests, also known as montane or sub-tropical forests, thrive in the cooler, moister conditions found at these altitudes. Higher elevations (2300+ metres) typically support different alpine vegetation types.
