Which statement explains why earthquakes tend to be deeper near subduction zones?
a. the plates at a subduction zone are thicker.
b. earthquakes occur near the edges of tectonic plates.
c. at a subduction zone, oceanic crust is forced deep into the earth.
d. subduction zones create transform faults, which can run down far into earth's crust.

Option C, At a subduction zone, oceanic crust is forced deep into the Earth.

Explanation:

At sub-duction zone, the dense oceanic plates coincides with the less dense continental plates and thus sink below the continental plates. Sometimes these oceanic plates being dense, sink to greater depth with in the earth’s mantle. The sub-duction zone causes  earth quakes of high intensity when oceanic crust penetrates to greater depths of earth crust as they tend to change the rheology of the earths’ mantle and also causes bending of plates

Hence, option C is correct

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
