Volcanoes are fascinating geological formations that can be found all over the world. They are openings in the Earth's crust where molten rock, ash, and gases erupt, forming various shapes and sizes. There are several main types of volcanoes, each with distinct characteristics and eruption styles.
1. Which type of volcano is characterized by its broad, gently sloping sides and effusive eruptions?
Cinder Cone
Stratovolcano
Shield Volcano
Caldera
2. Composite volcanoes are also known as:
Shield volcanoes
Cinder cones
Stratovolcanoes
Lava domes
3. Volcanoes that are built up from layers of ash, lava, and rock fragments are called volcanoes.
4. A volcano typically has a bowl-shaped crater at its summit and steep sides, formed from explosive eruptions.
5. The largest type of volcano, often with a very wide base and gentle slopes, is known as a volcano.
6. Shield volcanoes are known for their violent, explosive eruptions.
True
False
7. Cinder cone volcanoes are typically the largest type of volcano.
True
False
8. Describe the main differences between a shield volcano and a stratovolcano.
