Part 1

This diagram was similar to one Alfred Wegener drew to show the distribution of continents 300 million years ago. His theory of continental drift was met with skepticism in the scientific community.

1. Describe three forms of evidence Wegener used to support his ideas of continental drift.
• Continental Margins (Visually land masses fit together like a puzzle)
• Rock layers (similarity on the coast lines as well in a different continent
• Fossil evidence (How some animals were identical

Part 2

Write paragraph answers to the following questions using what you have learned from Visualizing Earth Science and the assigned WileyPlus® GeoDiscoveries®.

1. How does the motion of the tectonic plates affect the climate?
Plate tectonics has been known to have causes that cause a change in the ocean currents and in turn generates more heat. When these tectonic plates shift, the creation of the volcanic eruptions increases the degree of carbon dioxide and sulfur dioxide in the atmosphere. This is what leads to a rise in the temperature levels globally. Higher concentrations of sulfur dioxide could mean the Earth is becoming warmer at four times the rate of carbon dioxide concentration.
2. How does the motion of the tectonic plates affect the geography?
The movement of the plate techtonics over time can cause friction that leads to earthquack, geological changes, etc. The crashing of plates can change the landscape, create mountains and hills, etc. The creation of natural landscapes can occur.
3. How does the motion of the tectonic plates affect the distribution of organisms?
The motion of the tectonic plates can affect the distribution of organisms based on the different climate affects that they may have. Some organisms may have to evolve to survive a new environment or migrate to a new area in which they can survive,
