Assertion(A): Inside the earth especially inside the outer core the metals are present in molten state.
Reasoning(R): Earth absorbs the sun's rays.
Answer & explanation
Correct answer: option 2
The correct answer is Option 2: Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A.
Assertion(A): Inside the earth especially inside the outer core the metals are present in molten state. This is true. Deep inside the Earth (especially in the outer core), metals like iron and nickel are in the molten (liquid) state due to extremely high temperature and pressure.
Reasoning(R): Earth absorbs the sun's rays. This statement is also True. The Earth's surface and atmosphere absorb a significant portion of the sun's incoming solar radiation, which warms the planet.
The heat absorbed from the sun's rays primarily affects the Earth's surface, atmosphere, and shallow crust. Solar radiation penetrates only a very short distance into the Earth and has no significant impact on the temperature of the deep interior, including the outer core. The heat that keeps the outer core molten is entirely from internal sources. Hence, R does not explain A.
