Why might sedimentary rocks form in layers? Because of earthquakes Because of plate tectonics Because of volcanic activity Because sediments are often deposited in layers

Sedimentary rocks form in layers primarily because sediments are often deposited in layers. Over time, particles from various sources—like rivers, wind, or glacial activity—settle in different environments, creating distinct layers that reflect changes in the conditions at the time of deposition. Each layer can tell a story about the Earth's past, preserving clues about the environment when it was formed. Interestingly, these layers can reveal a lot about the Earth's geological history! For instance, by studying the sequence and composition of sedimentary layers, geologists can infer ancient climates, the biological evolution of life, and even significant events like mass extinctions. So, next time you see a rock formation with visible strata, think of it as a historical book waiting to be read!
