B. Unlike lava, pyroclastic material erupts from shield volcanoes.
C. Unlike lava, pyroclastic material is associated with explosive eruptions.
D. Unlike lava, pyroclastic material is associated with nonviolent eruptions.

A.Unlike lava, pyroclastic material erupts onto Earth’s surface.

Explanation:

The pyroclastic material is the one that erupts with an explosive volcanic eruption like that of lava eruption. The pyroclastic erupts by ejecting the fragments, resulting in ashfall deposits, it flows out with an ash deposit on the surface of the earth. The fragmented material spreads on the Earth's surface. The fragments are of grain size.

they are both the same distance away from the equator and from the poles. both circles are at 66 1/2 degrees. also they both form imaginary line borders of polar regions.
