Definitions:

Fluid Lava

Magma that has reached the surface through a volcanic eruption and flows easily due to its low viscosity.

Viscous Lava

Lava that is thick and slow-moving due to its high silica content, which increases its viscosity.

Scoria Cone

A type of volcanic cone formed from fragments of lava ejected from a single vent, characterized by its steep sides and often associated with basaltic lava flows.

Soil And Plants

The interdependent relationship between soil and plant life, where soil provides nutrients, water, and support for plants, and plants contribute to soil health and structure.
