Cinder Cone volcano is:

Cinder Cone volcano is:

• A. A steep, cone-shaped hill or small mountain made of volcanic ash, cinders, and bombs piled up around a volcano's opening
• B. A tall, cone-shaped mountain with layered lava and ash
• C. A broad, gently sloping volcano formed by low-viscosity lava
• D. A volcanic dome formed by rhyolite lava

Answer: (A)

A cinder cone is a small, steep-sided volcano built from erupted tephra—ash, cinders, and volcanic bombs—that pile up around a volcano’s opening. The eruptive material falls close to the vent and accumulates into a cone, often with a bowl-shaped crater at the top. This is distinct from stratovolcanoes, which are larger and formed by alternating layers of lava flows and ash; shield volcanoes, which have broad, gently sloping profiles from low-viscosity lava that travels far; and volcanic domes, which are rounded mounds formed by viscous rhyolite or andesite lava that piles up near the vent. The key feature is the construction from loose tephra around the vent, creating a sharp, cone-like hill.
