Explanation:

These questions are about Earth's geological features, plate tectonics, and related concepts. The subfield of Natural Science that applies here is Geology (under Geography or as a separate subfield, but Geography is listed and geology is part of Earth sciences which falls under Natural Science's Geography or related subfields). The answers to some key questions:

• 23: Mesosaurus (fossil evidence for continental drift)
• 24: Europe (Appalachian Mountains align with European mountain ranges due to continental drift)
• 25: glacial (old glacial ice in warm places shows past climate/continental positions)
• 26: ridges (mid - ocean ridges are underwater mountain ranges)
• 27: spreading (sea - floor spreading creates new ocean floor at mid - ocean ridges)
• 28: 1950s (Harry Hess proposed sea - floor spreading in the late 1950s)
• 29: magnetic (iron in magma aligns with Earth's magnetic field)
• 30: paleomagnetism (study of ancient magnetism in rocks)
• 31: lithosphere (thin, hard outer layer including crust and upper mantle)
• 32: asthenosphere (soft, flowing layer under lithosphere)
• 33: transform (transform boundaries have plates sliding past each other)
• 34: Pangaea (supercontinent 300 million years ago)
• 35: Panthalassa (ocean surrounding Pangaea)
