Task: Class Definition Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes 'thrust'?

A. A large-displacement (kilometers or tens of kilometers) shallowly dipping to subhorizontal fault or shear zone.
B. Right-lateral separation sense; in plan view, the side opposite the observer appears displaced to the right.
C. Reverse fault with dip typically less than 45 degrees; horizontal compression, rather than vertical displacement is characteristic.
D. The hanging wall appears to have moved down relative to the footwall; dip of fault usually greater than 45 degrees.

Answer: Reverse fault with dip typically less than 45 degrees; horizontal compression, rather than vertical displacement is characteristic.
