Question

question 10 of 25
why are there volcanoes on the ring of fire?
a. two plates are colliding.
b. radioactive elements decay.
c. there are no earthquakes.
d. there is no plate movement.

Explanation:

The Ring of Fire is a region where tectonic plates interact. When two plates collide (convergent plate boundary), one plate can be forced beneath another (subduction). This process can lead to magma formation and volcanic activity. Radioactive element decay (Option B) is related to heat in the Earth's interior but not the direct cause of Ring of Fire volcanoes. The Ring of Fire is known for both volcanic activity and earthquakes (so Option C is incorrect). Plate movement is a key factor in the Ring of Fire (so Option D is incorrect).

Answer:

A. Two plates are colliding.
