Why are so many volcanoes found on the Ring of Fire around the margin of the Pacific Ocean? a. Many hotspots occur there. b. Many subduction zones occur there. c. The climate is hot there, favoring volcano formation. d. The seafloor is spreading extremely fast there.

b. Many subduction zones occur there.

Explanation:

Many volcanoes are found on the Ring of Fire around the margin of the Pacific Ocean because of the occurence of subduction zones present there.

A subduction zone is a very mighty crash scene that shows the collision between 2 tectonic plates.

A subduction zone always has its oceanic crust sinking into the inner part of the earth under continental crust.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
