Assertion (A): Tidal range is not constant.

Reason (R): Tidal range varies due to the earth's rotation on its axis.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true but R does not explain A.

Explanation:

• Assertion (A): Tidal range is not constant
  True – The tidal range (difference between high tide and low tide) changes daily and over longer cycles (like during spring and neap tides).

• Reason (R): Tidal range varies due to the Earth's rotation on its axis
  Also true – Earth's rotation does influence tides, including their timing and distribution across the globe.
