Two plates composed of rock of similar density meet along a convergent boundary. Which statement describes what will happen where the two plates meet?
A. The plates will rub against each other, causing shearing and creating fault lines in the interior of the plates.
B. One plate will subduct underneath the other plate, forming a deep trench along the boundary.
C. The plates will collide, and the compression will heat the plates to melt and form volcanic mountains.
D. The plates will collide with neither plate subducting, causing the crust to pile up and form a mountain range.
D. The plates will collide with neither plate subducting, causing the crust to pile up and form a mountain range.

Which of these explains the feature that can form at the boundary of these two plates?
A. Island arc because the oceanic plate melts underneath the continental plate, forming volcanic mountains the eventually become islands.
B. A range of volcanoes because the oceanic plate melts underneath the continental plate, forming a line of volcanoes on the continent.
C. A broad canyon-like valley because the two plates act like a plow, digging out any soil in the plate's paths.
D. A mountain range because the two colliding plates have equal composition and density, causing both to fold and form wide, thick mountains.
