Science Blog: Continental Drift

I am going to be blogging about Continental drift.I know what you are saying what is Continental drift.Well I am going to blog about Alfred Wagner's theory of Continental drift and seafloor spreading.Hope you enjoy it.

First Alfred Wagner was a German Scientist.Alfred was born on November 1st 1880.He came up with the Continental drift theory in 1911.He was drafted into the German Army in 1914.

Here is a picture of Alfred Wagner.

Now I will explain what his theory was about.He was talking about how the Earth Was made up of one giant Continent called Pangaea.He had some evidence explaining his theory like plant and animal fossils.He said that people have found four legged creatures in South America when their home is in Africa.

Continental Drift is when the continents move around because of the mantles heat.What happens is that the mantles heat moves the tectonic plates. The tectonic plates move about 1-4 inches a year.

Here is a picture of Pangaea.

Seafloor spreading is something that happens at the oceans crust.Seafloor spreading is when two plates move away from each other because of the mantles heat.Like how South America keeps moving farther away from Africa.
