13. Theory of special relativity was developed by:
[A] Einstein
[B] Newton
[C] Galileo
[D] Laplace
Show Answer
Correct Answer: A [Einstein]
Notes:
Einstein proposed theory of special relatively in the year 1905. According to this theory
E=mc²
Where
C= Speed of light
M= relative mass of a body
E= Kinetic energy
It means that the amount of energy in a piece of matter is equal to the mass of that piece of matter multiplied by the speed of light squared.

[A] Core
[B] Crust
[C] Mantle
[D] Magma
Show Answer
Correct Answer: B [Crust]
Notes:
Structure of Earth’s interior is divided into three parts:
Outer most layer of the earth is known as Crust
Inner most layer of the earth is known as Core
Mantle is the layer that is lying between crust and core
18. Which of the following is known as most dense layer of the earth?
[A] Core
[B] Crust
[C] Mantle
[D] Magma
Show Answer
Correct Answer: A [Core]
Notes:
Core is the densest layer of the earth. The density of the core ranges from 9.5 to 14.5 and sometimes even higher. (13g/cm3)
The density of Mantle varies from 3.3 to 5.7 (3.4 gm/cm3)
Density of crust varies from 2.70 to 2.95 (3g/cm3)
19. Which of the following rocks formed from the existing rocks by undergoing the process of recrystallization?
[A] Igneous rocks
[B] Metamorphic rocks
[C] Sedimentary rocks
[D] None of the above
Show Answer
Correct Answer: B [Metamorphic rocks]
Notes:
The type of rocks that are formed from existing rocks through recrystallization are known as metamorphic rocks. The word metamorphic means ‘change of form’.
Igneous rocks are formed by the solidification of hot molten material called magma or lava. The word igneous is derived from the Latin word ‘ignis’ meaning fire.
Sedimentary rocks are formed by the deposition of sediments of rocks by exogenous forces. The word ‘sedimentary’ is derived from the Latin word sedimentum, which means settling.
20. Which of the following rocks have layered like structure?
[A] Igneous Rocks
[B] Metamorphic Rocks
[C] Sedimentary Rocks
[D] Extrusive igneous rocks
Show Answer
Correct Answer: C [Sedimentary Rocks]
Notes:
Sedimentary rocks are formed by the successive deposition of sediments. Therefore they have layered or stratified structure. These rocks are also known stratified rocks.
Sandstone, shale, limestone and dolomite are some of the examples of Sedimentary rocks.
