Final answer:
Cinder cone, shield, and composite volcanoes can be identified based on their characteristics.
Step-by-step explanation:
The three types of volcanoes are cinder cone, shield, and composite. Cinder cone volcanoes are small, steep-sided cones that are made up of loose rock fragments that are ejected during eruptions. Shield volcanoes are broad, gently sloping volcanoes that are formed by the eruption of fluid lava flows. Composite volcanoes, also known as stratovolcanoes, are tall, steep-sided volcanoes that are made up of alternating layers of lava, ash, and other volcanic materials.
In the pictures provided, the volcano in picture a) is a cinder cone volcano. It is characterized by its steep sides and conical shape. The volcano in picture b) is a shield volcano. It has a broad, gently sloping shape. The volcano in picture c) is a composite volcano. It is tall and steep, with a conical shape and layered appearance.
Therefore, the correct answers are a) Cinder cone, b) Shield, and c) Composite.
