Which features do most stratovolcanoes and cinder cone volcanoes have in common?

violent eruptions and thin, flowing lava

steep sides and violent eruptions

broad base with quiet eruptions

wide dome shape and thick lava

steep sides and violent eruptions

Option (2)

Explanation:

Strato-volcanoes are the steep, conical shaped, formed by the alternative beds of ash and lava. The magma in this type of volcano contains high silica content and are comprised of bubbles. When the gases are released from these bubbles, then a greater force is exerted from the bottom towards the surface. Due to this, they are very explosive and ejects a huge amount of materials during eruption. For example, Mount St. Helens.

Cinder cones are the simplest volcanoes with steep sides. They are made of the materials and semi solidified lava that are ejected from the vents of the volcano. Eruptions are often explosive due to the force exerted by the gas and the molten lava and are accumulated near the vent. For example, Paricutin.

These two types of volcanoes are similar in terms of its eruption that is violent and explosive in nature. In addition to that, they both have steep sides.

Hence, the correct answer is option (2).
