Explain how the uneven heating of the internal earth moves the lithospheric plates. List the evidence Alfred Wegner collected to support the single landmass hypothesis. Compare and contrast the major lithospheric plate boundaries. What landmasses does each form? Examples of each? Briefly explain why earthquakes and volcanoes occur with high frequency at crustal plate boundaries.
Understand the Problem
The question is asking for explanations and comparisons related to geological concepts such as the heating of the earth, evidence for continental drift, and characteristics of lithospheric plates. This indicates a focus on Earth sciences.
Answer
Uneven heating causes convection currents moving plates. Wegener showed fossils and coastlines as evidence. Boundaries form ridges, mountains, faults. Earthquakes/volcanoes frequent at boundaries due to tectonic movements.
Uneven heating causes convection currents that move plates. Wegener cited fossil evidence and coastlines. Divergent boundaries form mid-ocean ridges, convergent form mountains like the Himalayas, and transform boundaries create earthquakes like the San Andreas Fault. Earthquake and volcano activity occurs at these boundaries due to tectonic movement.

More Information
Convection currents in the mantle are crucial for plate movements. Wegener's observations laid a foundation for the theory of plate tectonics. Transform boundaries are particularly prone to earthquakes.
Tips
A common mistake is confusing different types of boundaries and misidentifying their associated geological features.
