Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The decrease of temperature with increasing latitudes in northern Atlantic Ocean is very high because of cold ocean currents. Reason (R): The temperature of the surface water of the oceans is higher than the air temperature above the ocean surface. In the light of the above statements, choose the correct answer from the options given below:

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true but R is NOT the correct explanation of A.
• C. A is true but R is false.
• D. A is false but R is true.

Hint:

\[ \boxed{ \text{Labrador Current} \rightarrow \text{Cold Current} \rightarrow \text{Lower Temperature} } \] Mnemonic: “Labrador = Low Temperature.”

Answer 1

The Correct Option is C

Concept: The rapid decrease in sea surface temperature towards higher latitudes in the North Atlantic is influenced by cold ocean currents such as the Labrador Current. The Reason is not universally true because ocean surface temperature is not always higher than the air temperature above it.

Step 1: Evaluate Assertion (A). \[ \boxed{\text{Assertion (A) is True}} \]

Step 2: Evaluate Reason (R). The stated relationship between ocean and air temperature is not universally correct. \[ \boxed{\text{Reason (R) is False}} \] Hence, \[ \boxed{\text{(C)}} \]
