What primarily characterizes sedimentary rock?

Sedimentary rock is primarily characterized by its formation from eroded products and mineral precipitation. This process involves the accumulation, compaction, and cementation of sediments, which can include fragments of other rocks, minerals, and organic materials. Over time, these sediments are deposited by water, wind, or ice and then compacted under pressure. Additionally, minerals can precipitate out of solution, forming layers of rock. This mechanism is fundamental to understanding sedimentary rocks as it highlights their origins and the environments in which they form.

The other options focus on processes that define different types of rocks. For example, the formation through solidification of magma pertains to igneous rocks, which form when molten rock cools and solidifies. High temperature and pressure are characteristic of metamorphic rocks, which are formed from the alteration of existing rocks under these conditions. While organic material can indeed contribute to some sedimentary rocks, such as limestone formed from coral or shell fragments, the broader category focuses on the role of eroded materials and precipitated minerals. Thus, the correct answer reflects the comprehensive processes involved in the formation of sedimentary rocks.
