what sequence of events could lead to magma becoming soil?
crystallization followed by increased heat and pressure.
erosion and deposition followed by exposure to heat and pressure.
compression and lithification followed by erosion and deposition.
crystallization followed by exposure and weathering.

Explanation:

1. First, magma cools and crystallizes to form igneous rock.
2. Then, over time, this igneous rock is exposed at the Earth's surface (through processes like uplift) and undergoes weathering (physical, chemical, or biological breakdown) and erosion. These processes break down the rock into smaller particles, which, along with organic matter and other components, eventually form soil.
3. Let's analyze the other options:

• "Crystallization followed by increased heat and pressure" would lead to metamorphism, not soil formation.
• "Erosion and deposition followed by exposure to heat and pressure" is more related to sedimentary rock metamorphism, not soil from magma.
• "Compression and lithification followed by erosion and deposition" is about sedimentary rock formation and movement, not starting from magma to soil.

Answer:

D. Crystallization followed by exposure and weathering.
