c. Pretend there was no plate tectonics and the Pangea continent never came apart. Do you feel like there would be more or less species diversity on the planet? Explain your answer. Text here

## Step 1<br />The problem is asking us to consider the hypothetical scenario where there was no plate tectonics and the Pangea continent never came apart. This would mean that the Earth's landmass would have remained largely unchanged over billions of years.<br /><br />## Step 2<br />Plate tectonics is a theory that explains the movement of the Earth's lithosphere. This theory is responsible for the formation of mountains, earthquakes, and the creation of new crust at mid-ocean ridges. It also explains the distribution of fossils and the similarity of rock formations across continents.<br /><br />## Step 3<br />The movement of these plates has led to the isolation of populations of organisms, which has allowed for the evolution of new species. This process is known as allopatric speciation.<br /><br />## Step 4<br />If there was no plate tectonics, the Earth's landmass would have remained largely unchanged over billions of years. This would have meant that populations of organisms would not have been isolated, and thus, there would have been less opportunity for allopatric speciation to occur.<br /><br />## Step 5<br />Therefore, in this hypothetical scenario, there would likely be less species diversity on the planet.
