Plate

Question 42

States that the outermost layer of is divided into a dozen more plates, which are moving relative to one another as they ride atop hotter, more mobile material. (Crust is divided into plates which are in constant motion.)

Answer 42

Theory of Plate Tectonics

Question 43

Stated that the Earth’s continents today originated | from a supercontinent which slowly drifted away.

Answer 43

Continental Drift Theory

Question 44

Who proposed the Continental Drift Theory?

Answer 44

Alfred Wegener

Question 45

Why was the Continental Drift Theory rejected?

Answer 45

because there was no concrete mechanism presented.

Mesosaurus

Question 48

Its remains was found in all continents

Answer 48

Glossopteris

Question 49

What does Sea Floor Spreading state?

Answer 49

Stated that hot rocks slowly rise and spread out. This causes magma to ooze out, where it results to new oceanic crust.

Question 50

Who proposed seafloor spreading?

Answer 50

Harry H. Hess

Question 51

Explain Sea Floor Spreading

Answer 51

Magma rises causing the sea floor to spread and the oceanic crust to go back under the earth, recycling the sea floor.
