Who is the person credited with developing the theory of continental drift?

• Harry Hess

• Donald Trump

• Alfred Wegener

• Sir Isaac Newton

According to the theory of continental drift,

• Earth's surface is made up of seven major landmasses

• the continents DO NOT move

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass, and these plates will continue to move.

• crustal integrating

• sea-floor spreading

• subduction
