The carboniferous period belongs to the era:

A
Precambrian

B
Palaeozoic

C
Cenozoic

D
Archaeozoic
Question 2
1 / -0

Where does divergent plate boundary occur?

A
Seafloor

B
Ocean ridges

C
Basins

D
Himalayas
Question 3
1 / -0

Mesozoic era is called golden period of ___________

A
Birds

B
Amphibians

C
Reptiles

D
Pisces

Solution

In the Mesozoic era, the dinosarus dominate the Earth. Therefore, Mesozoic era is called as the golden period of reptiles.
Question 4
1 / -0

Hardy - Weinberg principle of zero evolution is based on:

A
Genetic equilibrium.

B
Random mating.

C
No migration.

D
All of the above.
Question 5
1 / -0

The flourishing period of progymnosperm is:

A
Devonian.

B
Silurian.

C
Cretaceous.

D
Permian.
Question 6
1 / -0

Plates move away from each other, in the

A
Transform fault boundary

B
Convergent plate boundary

C
Divergent plate boundary

D
Tectonic plates
Question 7
1 / -0

Life on earth begins, approximately

A
2.9 billion years ago

B
3 billion years ago

C
4.6 billion years ago

D
2.6 billion years ago
Question 8
1 / -0

The age of the fossil of Dryopithecus on the geological time scale is

A
75 x 10$$^{6}$$ years back

B
25 x 10$$^{6}$$ years back

C
2.5 x 10$$^{6}$$ years back

D
50 x 10$$^{6}$$ years back

Solution

Miocene fossils of forest-dwelling, chimpanzee-sized apes were called dryopithecines. They lived around about 15 to 25 mya.
Question 9
1 / -0

The age of rock is calculated on the basis of

A
Types of fossils present

B
Amount of lead present

C
Amount of uranium present

D
ratio of amount of Lead to Uranium

Solution

The age of the rock can be determined by radioisotope dating. This is done by calculating daughter to parent ratio of the radioactive element. For example, that of Lead to Uranium. Uranium decay to Lead releases $$\alpha$$ particles. After first half life, amount of Lead present is 50% and amount of Uranium is 50% which requires 4.5 billion years, after second half life amount of Lead is 75% and amount of Uranium is 25%, so, the ratio 3:1 and age 9 billion years.. and so on.
So, the correct answer is ' ratio of amount of Lead to Uranium'
Question 10
1 / -0

Hardy and Weinberg principle explains

A
Genetic equilibrium

B
Non random mating

C
Evolutionary force

D
All of the above
