Question

when a volcano erupts, tiny particles from which of earths spheres are released into the air?
atmosphere
biosphere
geosphere
hydrosphere

Explanation:

• The geosphere includes the solid parts of the Earth (rocks, minerals). Volcanoes are part of the geosphere as they are made of rock and magma (which is from the Earth's interior, part of the geosphere). When a volcano erupts, the tiny particles (ash, etc.) are from the geosphere.
• The atmosphere is the air around the Earth. The biosphere is the living part of the Earth. The hydrosphere is the water part of the Earth.

Answer:

geosphere
