1. What is continental drift?
Is a theory that shows how continents shift on the earth’s surface.
Explained why look-alike plant fossils and animals, and similar rock formations, are found on different continents.
2. What was Alfred Wegener’s hypothesis for continental drift, and why was his idea not accepted?
He suggested that the continents plowed across the ocean floors but could not explain the information properly.
Wegener could not identify the cause of continental drift and thus having most geologists reject his idea, and even with that he continued to update his book and collect evidence.
3. Explain the evidence collected in the last part of the 20th century that supports Wegener’s continental drift theory.
In the last part of the 20th century the geographic evidence to support the theory of continental drift is that Alfred Wegner wrote a book explaining the continental drift philosophy.

The Different types of plate boundaries are:
1. Divergent - Almost all the Earth's new crust forms at divergent boundaries, but most are not known because they lie deep under the oceans. These are zones where two plates move away from each other, allowing magma from the mantle to rise up and make a new crust. Divergent boundaries are where the plates move apart. Seafloor spreading is a process in which the magma creates new land under water.
2. Convergent - The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench. A chain of volcanoes often forms parallel to the boundary, to the mountain range, and to the trench. Powerful earthquakes shake a wide area on both sides of the
