according to the theory of plate tectonics, the lithosphere consists of:
hot spots that float up from the mantle.
several rigid plates that float on the asthenosphere.
an unbroken solid mass that surrounds the molten interior.

30 multiple choice 2 points
the theory of continental drift says that:
neither of these answers are true.
the continents have always been separate but may one day drift together to form a single continent.
all the continents were once one continent that broke up and drifted apart over hundreds of millions of years.

Explanation:

• En un límite transformante en la teoría de las placas tectónicas, las placas se deslizan una al lado de la otra.
• La litosfera está formada por varias placas rígidas que flotan sobre la astenosfera.
• La teoría del derrame continental sostiene que todos los continentes alguna vez formaban un solo continente que se rompió y se separó a lo largo de cientos de millones de años.

Answer:

• 1. plates slide past each other.
• 2. several rigid plates that float on the asthenosphere.
• 3. all the continents were once one continent that broke up and drifted apart over hundreds of millions of years.
