Which of the following describes rotary drilling?

Rotary drilling is characterized by the use of a rotating bit, which is designed to penetrate the earth's crust efficiently. This technique involves turning a drill bit that can cut through various geological formations, allowing for deeper drilling compared to other methods. The rotation creates a shearing action that is effective in breaking rock and other materials, which is essential for extracting resources such as oil and natural gas.

This method is contrasted with other drilling techniques that might rely on static pressure or may be limited to shallow depth applications. By focusing on rotation, rotary drilling enables more diverse and deeper drilling operations, making it a widely used method in the industry for accessing subsurface resources.
