Question

which geologic features would be expected at a continental - continental convergent boundary?
a coastal mountain range
earthquake activity and a mountain range
volcanic island arcs and earthquakes
continental volcanic mountains

Explanation:

Continental-continental convergent boundaries occur when two continental plates collide. Neither plate subducts (both are low density), so volcanic activity from subduction does not happen. Instead, the crust crumples and uplifts to form mountain ranges, and the intense pressure and movement cause frequent earthquake activity. Coastal mountain ranges form at ocean-continental boundaries, volcanic island arcs form at ocean-ocean boundaries, and continental volcanic mountains are linked to subduction of oceanic plates under continents.

Answer:

B. earthquake activity and a mountain range
