A Mercator projection map would be useful for comparing the sizes of continents as it preserves the shapes of continents but distorts their sizes, making it easier to visually compare.
A globe is useful because it provides a three-dimensional representation of the Earth, making it easier to understand the Earth's geographic features and relationships between countries and continents. It also allows for easier visualization of how the Earth rotates and orbits the sun.
Research station-centric telephone systems work well; ISat phones are available to connect with other continents, and decayed-orbit satellites are also useful for communication to other continents.
Clues useful in reconstructing Pangaea include the matching shapes of continents' coastlines, similarities in rock formations and fossils across continents, and the alignment of mountain ranges and geological structures. Additionally, paleoclimatic evidence such as glacial deposits and ancient climate patterns can provide further support for the theory of Pangaea.
Fossils are more useful than rock types in correlating rock layers on different continents because they provide direct evidence of ancient life forms that can be compared and matched across continents. Fossils can also help determine the relative ages of rock layers, which is crucial for understanding the timing and sequence of events in Earth's history. In contrast, rock types can vary widely between continents, making direct correlations more challenging.
Some clues useful for reconstructing Pangaea include similarities in rock formations and fossils across different continents, matching mountain ranges and coastlines, and geologic evidence such as glacial striations that suggest movement of continents. Additionally, the fit of continental shelves and distribution of certain plant and animal species provide further evidence for the existence of Pangaea.

Fossils of similar plants and animals found on different continents, matching mountain ranges and geological formations, and similarities in ancient climates and rock formations are all clues used to reconstruct Pangaea. These pieces of evidence suggest that the continents were once joined together in a supercontinent.
