Final answer:
Physical geographers primarily focus on studying the Earth's surface and do not study beneath it.
Step-by-step explanation:
Physical geographers primarily focus on studying the Earth's surface. They analyze the physical characteristics of the planet, such as landforms, climate, and natural phenomena like rivers and mountains. While there are geologists who study the Earth's crust and processes that shape its surface, physical geographers typically do not study beneath the Earth's surface because it is not within the scope of their field. They use tools and methods to study and analyze the Earth's surface, such as satellite imagery, remote sensing, and geographical information systems (GIS).
