In Sedimentary rock formation, when particles are pressed together with gravity and pressure

Answer 1

In sedimentary rock formation, particles such as mineral fragments, sand, silt, and clay are deposited by various processes such as erosion, weathering, and transportation. Over time, these particles accumulate in layers on the Earth's surface.

As more and more sediment is deposited, the weight of the overlying layers increases, exerting pressure on the lower layers. This pressure, combined with the force of gravity, causes the particles to become tightly packed and compacted.

The particles are initially loosely arranged and may contain air or water-filled spaces between them. However, as the pressure increases, these spaces are gradually squeezed out, and the particles become more tightly packed.

The force of gravity also contributes to the compaction process by pulling the particles closer together. This gravitational force acts on each individual particle, causing them to settle and settle more closely together.

As the sediment becomes compacted, the contact between the individual particles increases, and the loose sediment gradually transforms into a more solid rock mass. The pressure and gravity exerted on the sediment over millions of years can lead to the formation of dense and durable rock types such as sandstone, limestone, and shale.

In summary, the process of sedimentary rock formation involves the compaction of loose sediment particles under the influence of gravity and pressure. This compaction gradually transforms the sediment into solid rock, creating distinct layers or strata in the process.
