Consider how sedimentary rocks are formed from smaller particles called sediments. Sediments are composed of particles that often come from existing rocks. How are these particles produced?
A)weathering
B)decomposition
C)compaction
D)deposition
The correct answer is A) weathering.
Particles that make up sediments are often produced through the process of weathering. Weathering is the breakdown of rocks and minerals at or near the Earth's surface, and it can occur through physical, chemical, or biological processes. Physical weathering involves the mechanical breakdown of rocks into smaller pieces, while chemical weathering involves the alteration of minerals in rocks through chemical reactions. Both forms of weathering can produce particles that eventually become sediments and form sedimentary rocks.
