Question

Which type of volcanoes have steep slopes and are associated with explosive eruptions?

A) Shield volcanoes
B) Composite Volcanoes
C) Cinder Cone volcanoes
D) Caldera volcanoes

Answer 1

B) Composite Volcanoes is type of volcanoes have steep slopes and are associated with explosive eruptions

Step-by-step explanation:

Here's why:

1. Composite volcanoes, also known as stratovolcanoes, are characterized by their steep slopes and conical shape.

2. These volcanoes are formed by alternating layers of lava flows and volcanic ash and debris.

3. Composite volcanoes are associated with explosive eruptions due to the presence of highly viscous magma.

4. The viscosity of the magma in composite volcanoes traps gas bubbles, leading to a build-up of pressure.

5. When the pressure becomes too great, explosive eruptions can occur, sending ash, rock fragments, and pyroclastic flows into the air.

6. Examples of composite volcanoes include Mount St. Helens in the United States, Mount Fuji in Japan, and Mount Vesuvius in Italy.

7. The explosive nature of composite volcanoes makes them potentially dangerous, as eruptions can cause significant damage to surrounding areas and pose risks to human life.

In summary, composite volcanoes have steep slopes and are associated with explosive eruptions. They are formed by layers of lava flows and volcanic ash, and their explosive nature is due to the presence of viscous magma and trapped gas bubbles. Examples of composite volcanoes include Mount St. Helens, Mount Fuji, and Mount Vesuvius.

The correct answer is B) Composite Volcanoes.

Answer 2

Composite Volcanoes are the type of volcanoes with steep slopes and are associated with explosive eruptions due to their type of magma that comes from subduction zones at convergent plate boundaries.

Step-by-step explanation:

The type of volcanoes associated with steep slopes and explosive eruptions is B) Composite Volcanoes. Composite volcanoes, also known as stratovolcanoes, are characterized by layers of hardened lava, tephra, and volcanic ash. These volcanoes often form at convergent plate boundaries, where the denser oceanic plate subducts beneath the overriding plate, a process that can generate powerful explosive eruptions due to the high gas content and viscosity of the magma.
