Question

1. the formation of earth involved: a) gradual, peaceful accumulation of materials b) violent collisions and planetary interactions c) consistent gravitational attraction d) uniform solar system development

Explanation:

The Earth formed through the gradual accumulation of materials in the early solar - nebula. This process involved the accretion of dust and small particles that stuck together through gravitational and electrostatic forces. Over time, these small bodies grew larger through collisions and gravitational attraction. While there were violent collisions and planetary interactions during the later stages of planet - building, the initial formation was a gradual accumulation of materials.

Answer:

A. Gradual, peaceful accumulation of materials
