26.
What is the fundamental difference between Alfred Wegener's Continental Drift Theory and the modern theory of Plate Tectonics?
Continental Drift theory suggests continents move, while Plate Tectonics suggests they are stationary.
Continental Drift was proposed in 1967, while Plate Tectonics was proposed in 1912.
Continental Drift proposed that continents plow through the ocean floor, while Plate Tectonics posits that continents are part of larger plates that move.
There is no fundamental difference; Plate Tectonics is just another name for Continental Drift.
Explanation: The core conceptual shift is that Wegener envisioned continents moving independently. Plate Tectonics, as described in the text, explains that "Continents are part of these plates and move with them." The plates themselves are the moving units.

Reason (R): The Labrador Current, a cold current, lowers temperatures along the northeast coast of North America.
A is false but R is true.
A is true but R is false.
Both A and R are true but R is not the correct explanation of A.
Both A and R are true and R is the correct explanation of A.
Explanation: Assertion (A) is a correct general rule stated in the text. Reason (R) is also a correct statement from the text. However, R is a specific example of a cold current's effect, not the reason *why* cold currents are generally found on west coasts. The underlying reasons (related to oceanic gyres and atmospheric circulation) are not given in the text. Therefore, both are true, but R is not the explanation for A.
77.

Assertion (A): Plate Tectonics is a more modern and comprehensive theory than Continental Drift.
Reason (R): Plate Tectonics explains the mechanism of movement (plates moving over the asthenosphere) which was a weakness in Wegener's original theory.
Reason (R): Plate Tectonics explains the mechanism of movement (plates moving over the asthenosphere) which was a weakness in Wegener's original theory.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
Both A and R are true and R is the correct explanation of A.
A is false but R is true.
Explanation: Assertion (A) is correct; the text calls Plate Tectonics a "modern theory" that provides a "more comprehensive explanation." Reason (R) is also correct and directly explains *why* it is more comprehensive. It provides the mechanism for movement (the movement of lithospheric plates over the asthenosphere), which was the main point of contention with Wegener's theory. Therefore, R is the correct explanation for A.
