The sun gets its energy from Nuclear fusion.

• Nuclear fusion is the process where the nuclei of two light atoms combine to form a new nucleus.
• Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between reactants and products is manifested as either the release of the absorption of energy. This difference in mass arises due to the difference in atomic binding energy between the nuclei before and after the reaction.
• Fusion is the process that powers active or main sequence stars and other high-magnitude stars, where large amounts of energy are released.

Lower layers of atmosphere have high pressure because the density is greatest at lower layers and are compressed. Higher layers of atmosphere have low pressure because they are less compressed.

We have S + 6 = Y
D + 6 = J
And similarly H + 6 = N
K + 6 = Q
So the correct answer is NQ.

All Girls and students are Human. A girl can be a student as well.

Hence, option C is the right choice.

38 L 2 M 7 P 4 N 22 = (38/2) + (7*4) - 22 = 19 + 28 - 22 = 25
Hence, option B is right choice.

The type of erosion involving rubbing, grinding, abrading and polishing the rock surfaces by any natural agent (wind, water or ice) with the help of its lead while passing over the rocks is termed as abrasion.

The sandstones are most commonly used as materials of construction: building stones, pavement stones, road stones and also as a source material for concrete. The Red Fort of India is made up of red sandstones.

The mantle extends up to the depth of 2900 km and from that depth it is the core that is said to be present and the radius of the Earth is 6371 km and hence the core is said to extend till 6371 km.

Anticlines are defined as those folds in which the limbs dip away from each other at the crest in the simplest forms.

The number, size and inclination of the shear zones should be given top consideration.

A group of beds or some veins or dykes may abruptly terminate along a surface in a given region. This may generally be due to breaking of the strata into blocks and movement of the disrupted blocks away from each other.

An exposed or covered surface may be suspected of being a faulted surface if it polished, and carries grooves and striations.

Tension joints are those, which have developed due to the tensile forces acting on the rocks. The most common location of such joints in folded sequence is on the outer margins of crests and troughs.

In normal faults, the fault plane may be inclines at any angle between horizontal and vertical, but most commonly, the fault angles are between 45° and vertical.

The term foot wall is used for that faulted block which lies on the under surface of the fault plane or zone.
