Here's a breakdown:
* Marine Sediments: These are the remains of organisms (like shells, bones, and skeletons) and other materials (like sand, clay, and mud) that settle at the bottom of the ocean.
* Heat and Pressure: Over time, these sediments get buried deeper and deeper. The weight of the layers above creates immense pressure, and Earth's internal heat provides a source of energy.
* Transformation: This heat and pressure cause the sediments to undergo a process called lithification. During lithification, the sediments are compacted, dissolved minerals are re-crystallized, and the sediments cement together to form a solid rock.
Examples of sedimentary rocks formed from marine sediments:
* Limestone: Formed primarily from the remains of marine organisms, like shells.
* Sandstone: Formed from sand grains, often deposited in coastal environments.
* Shale: Formed from fine-grained mud, deposited in quiet, deep-water environments.
