How do sedimentary rocks form on Earth's surface? A in vertical stripes (B) with no clear pattern (D) in horizontal layers ( crisscross pattern

Sedimentary rocks are primarily formed through the accumulation of sediments like sand, silt, and clay, which settle in horizontal layers over time. This layering occurs due to various processes like erosion, transportation by water, and deposition in environments such as riverbeds, lakes, and ocean floors, creating distinct, flat bands that can later be compacted and cemented into rock. One of the coolest real-world applications of sedimentary rocks is in the field of paleontology! Fossils, the remains of ancient life, are often found within these layers, providing valuable insights into Earth's history and the evolution of life. So, every time geologists study sedimentary rocks, they’re unlocking secrets about our planet’s past.
