Dense forests are the forests that have a tree canopy of more than ________.

  1. $40\%$
  2. $60\%$
  3. $50\%$
  4. $70\%$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to the Forest Survey of India, dense forests (which include both moderately dense and very dense forests) are defined as lands with a tree canopy density of 40% or more. Open forests have a canopy density between 10% and 40%, while scrublands fall below 10%.

Spruce and cedar are tree varieties of ____________.

  1. equatorial forest

  2. temperature forest

  3. monsoon forest

  4. temperature deciduous forest
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Spruce and cedar are coniferous evergreen trees characteristic of temperate montane or coniferous forests (such as those in the Himalayas). They are not deciduous, making the general temperate forest category the correct choice.

Multiple choice

Conifers have

  1. Needle like leaves

  2. Woody cones that contain their seeds

  3. Milk for snacks

  4. conical shape

A,B,D Correct answer
Multiple choice

Which of these is an evergreen tree?

  1. Mahogany

  2. Semul

  3. Sandalwood

  4. Deodar
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mahogany is a classic example of a tropical evergreen tree found in regions with heavy rainfall. In contrast, Semul and Sandalwood are deciduous trees, and Deodar is a coniferous mountain tree.

Multiple choice

Coniferous trees are conical in shape.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coniferous trees have a distinct conical shape with sloping branches, which helps them survive in snowy mountain regions by allowing snow to easily slide off without breaking the branches.

Multiple choice

Evergreen forests shed there leaves at the same time of the year.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Evergreen forests do not shed all of their leaves at the same time of the year, which is why they retain their green appearance year-round. In contrast, deciduous forests shed all their leaves during a specific dry or cold season.

Multiple choice

What type of tree is able to remain green during the winter time?

  1. oak trees

  2. deciduous trees

  3. conifers

  4. magnolia trees
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Conifers (such as pines, firs, and spruces) are evergreen trees that retain their needles and remain green throughout the winter. Deciduous trees, like most oaks, shed their leaves in autumn.

Multiple choice

which of these is not a sustainable use of rain forests? 

  1. Planting trees

  2. Chopping down trees

  3. Teaching people how to look after the rainforest

  4. Only chopping some trees
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Chopping down trees (clear-cutting or deforestation) destroys the ecosystem and is not sustainable. Sustainable practices, like planting trees or selective logging (only chopping some trees), allow the forest to recover and persist for future generations.

Multiple choice

Why have certain trees adapted to have Buttress Roots?

  1. To help animals to climb them

  2. To help them become more stable in thin soil

  3. To make them look funny

  4. To provide a place for animals to hide behind
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rainforest soils are often very thin and nutrient-poor, meaning tree roots do not grow very deep. Buttress roots are large, wide roots that grow above ground to provide structural stability and prevent tall trees from falling over.

Multiple choice

  1. a pine tree

  2. an apple tree

  3. an oak tree

  4. bamboo
Reveal answer Fill a bubble to check yourself

The moss which forms dense extensive mats on the soil prevents __________________.

  1. uprooting of trees

  2. soil erosion

  3. falling of leaves

  4. evaporation of water from the soil
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mosses form a protective covering over the crumbling soil of cliffs and prevent the rushing rainwater from cutting deeply into the soil. These grow in dense mats so firmly intertwined around the soil particles that there can be little erosion, even on a steep hillside.

So the correct option is B.
