Continental Drift

The theory used to describe that continents were not spread across the world were all once together. Then once the continental drift began the tectonic plates started to move and the continents separated from one another. Pangea is the most famous prediction of what the earth would look like before continental drift.

Fossil Evidence

Fossil evidence is when fossils of the same species are found in different continents. And they cannot transport to another continent. Supporting the theory of continental drift and how the continents were once together.

Rock Evidence

Rock evidence can be matched up with other different kind of rocks in different continents. They can all be traced back to one spot. Wegener discovered that mountains like the appalachians and caledonian mountains align perfectly together.

Plate Tectonics

Plate tectonics the theory that earth has layers. They all have a special purpose to protect earth. All of earths layers act strong and rigid to protect us especially the outer strongest layer the lithosphere.

Seafloor Spreading


    Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed through volcanic activity and then moves away. Seafloor spreading helps explain continental drift theory and plate tectonics. Seafloor spreading often affects mostly the middle point of an ocean.

Earthquake and Volcano Mapping

Earthquake and volcano mapping is the ability to be able to read a map and tell where the points are. Earthquakes often happen nearer volcanoes that is if the volcano is under water or above ground. You can often see on a map that the points are usually close to the edge of the land that the points are on.

Hot Spots

Hotspots an area where there is active volcanic activity. They were thought to be caused by a narrow stream of hot mantle from the core boundary called a plume. The latest evidence is pointing to upper-mantle convection as a cause.
