Only continental drift theory explains the climates on the continents have changed over time.

Only plate tectonics theory explains the patterns of earthquakes and volcanic eruptions on Earth.

Detailed explanation-1: -Plate tectonics explains why Earth’s continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is more complete. It has gained widespread acceptance among scientists.
Detailed explanation-2: -The continents are embedded in the plates. Many continents occur in the middles of plates, not at their boundaries or edges. Plates also underlie the Earth’s oceans. A single plate often includes both continental and oceanic regions.
Detailed explanation-3: -What are the differences between Continental Drift and Plate Tectonics? Continental drift believes that the continents moved because the magnetism of the sea floor. Plate tectonics believes that the lithosphere & the asthenosphere of the continents caused them to move.
Detailed explanation-4: -The Theory of Continental Drift is defined as the movement of the Earth’s continents relative to each other, thereby appearing to drift together across the oceanic bed.
Detailed explanation-5: -There are two main types of tectonic plates: oceanic and continental. Oceanic-Oceanic plates consist of an oceanic crust called “sima". Sima is made up primarily of silicon and magnesium (which is where it gets its name). Continental-Continental plates consist of a continental crust called “sial".
