كويز تفاعلي: 10 Questions: Development of a Theory

This assessment covers the scientific concepts behind the development of the theory of plate tectonics and seafloor spreading. It includes questions on oceanic mapping technologies like echo sounders, the discovery of mid-ocean ridges and rift valleys by scientists like Marie Tharp, and the movement rates of tectonic plates. Additionally, it distinguishes between geological materials such as magma and lava and explains the age patterns of rocks found on the seafloor.
