Final answer:
Clouds of tiny particles emitted from a volcanic eruption are called pyroclastic clouds. These clouds consist of fragments of rock, minerals, and volcanic glass that are created during volcanic eruptions and are smaller than 2 mm in diameter.
Step-by-step explanation:
Clouds of tiny particles emitted from a volcanic eruption are called pyroclastic clouds. These clouds consist of fragments of rock, minerals, and volcanic glass that are created during volcanic eruptions and are smaller than 2 mm in diameter. These particles, also known as volcanic ash, can have a significant impact on the climate, causing short-term climate changes and cooling the climate.
