Who discovered the crust of earth?

Answer 1

Know one really knows who discovered the Earth's crust.

The earliest geologists were Islamic scholars in western Asia (circa 1000 AD), who studied how seas may have later become mountaintops. The idea of a separate "crust" atop an elastic mantle developed through the late 19th century, from observations of upthrust mountains, spreading seafloor and subduction along the edges of continents. German geologist Alfred Wegener first proposed the theory of continental drift in 1912.

Answer 2

The crust of the Earth was not discovered by one single person. The understanding of Earth's crust developed over time through the work of various geologists and scientists, such as Alfred Wegener, who proposed the theory of continental drift, and Arthur Holmes, who contributed to the theory of plate tectonics.
