Final Answer:
Extrusion best describes the process by which magma reaches Earth's surface during a volcanic eruption. Option C is the answer.
Step-by-step explanation:
Volcanic eruptions involve the movement of magma from beneath the Earth's surface to the exterior. Extrusion, option C, accurately characterizes this process. During an eruption, magma is forced to the surface through volcanic vents, resulting in lava flows or other volcanic activities.
Options A, B, D, and E represent different geological processes unrelated to the ascent of magma during a volcanic eruption. Sublimation (Option A) involves the transition from a solid to a gas, deposition (Option B) is the settling of particles, metamorphism (Option D) is the alteration of rocks due to heat and pressure, and erosion (Option E) is the wearing away of geological features by natural forces.
Option C is the answer.
