Explanation:

Question 1

Pangaea is defined as a supercontinent that included all the Earth's continents in one landmass. Option A is about an ice sheet, B about a fossil, C about a mountain belt—none match. D correctly describes Pangaea.

The theory of continental drift states that continents move slowly across Earth’s surface over time. Option B says they moved but are now fixed (incorrect), C says they were fixed and now move (incorrect), D says they are fixed (incorrect). A matches the theory.

Alfred Wegener proposed the theory of continental drift. Harry Hess, Drummond Matthews, and Fred Vine were involved in plate tectonics/seafloor spreading, not the initial continental drift theory.

Answer:

D. a supercontinent that contained all the continents
