D. Advances in technology were needed to gather more evidence.

Explanation:

New technologies had to be developed to ascertain Wegener's claims.

The major flaw in Wegener's postulate was that the moving continents lacked a mechanism to drive them into motion.

His theory needed more scientific backing also.

  • A major leap was made when new technologies used during the second world war was deployed to investigate the ocean floor.
  • Sequences of magnetic anomalies were unraveled using equipment developed during the second world war
  • This gave further proof to the idea of continental drift and it expanded the theory into a more broader and inclusive theory of plate tectonics.

Why does sound propagate faster in solid bodies than in liquids and faster in liquids than in air?
storchak [24]

Answer:

see below

Explanation:

this is because particles in solids are packed very closely together, thus , the particles collide with each other frequently and thus transfer of energy is faster. however, particles in liquid are closely packed but not as close as in solid so the particles do not collide as frequently. thus, transfer of energy slower than in solid. furthermore, the particles in gas are spaced far apart from each other, thus the particles don't collide with each other frequently, thus transfer of energy is very slow in gas.

hope you get it,

please mark

Tcecarenko [31]

For instance, when the red lights are flashing , it simply means to stop, while the green light means that the vehicle can continue to move, and yellow light means to be at alert to move.
