Final answer:
A pyroclastic flow is not the same as a Lahar. Around 500 million people live near active volcanoes globally. There are approximately 70 volcanic eruptions each year. Ash and aerosols released during volcanic explosions can reflect solar energy and cool the Earth.
Step-by-step explanation:
A pyroclastic flow is not the same as a Lahar. A pyroclastic flow is a fast-moving cloud of hot gas, ash, and volcanic particles that moves down the side of a volcano during an eruption. On the other hand, a Lahar is a type of mudflow that can occur when volcanic ash and debris mix with water.
About 500 million people live near active volcanoes around the world. These areas are often attractive for settlement due to fertile soil and natural resources, but they also carry the risk of volcanic hazards.
There are actually about 70 volcanic eruptions expected each year. While some eruptions receive more media attention than others, volcanoes are constantly active around the world, although many eruptions are relatively small and occur in remote locations.
Ash and aerosols released during a volcanic explosion can indeed reflect solar energy and cool the Earth. This is due to the small particles scattering and reflecting incoming sunlight back into space, reducing the amount of solar energy reaching the Earth's surface.
