Which of the following occurs at convergent plate boundaries?
a.
subduction zone
b.
island arc
c.
mountain formation
d.
all of the above

Option (D)

Explanation:

In a convergent plate motion, the two plates move towards each other. Due to this, a subduction zone is created that is often marked by a deep-sea trench. It also results in the deep-focus earthquakes. Here, the subducting plate mixes with the melt at great depth and the magma eventually rises up forming island arcs and volcanic arcs.

In an oceanic-oceanic convergent boundary, island arcs are formed and in the continental-oceanic convergent boundary, volcanic arcs are formed.

Lastly, in the continental-continental convergent boundary, huge mountain belts like Himalaya are formed.

Thus, the correct answer is option (D).

the median of the data is 4.5.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
