* Solar Energy Drives Weathering: The sun's heat causes temperature fluctuations, which break down rocks through physical weathering. Water, expanded by the sun's heat, also contributes to weathering.
* Solar Energy Fuels the Water Cycle: The sun's energy evaporates water, which then condenses and falls as rain. This water flow erodes and transports weathered rock fragments, eventually depositing them in layers.
* Solar Energy Powers Photosynthesis: Photosynthesis by plants and algae produces organic matter that can form coal and other sedimentary rocks.
While the sun's energy is crucial for sedimentary rock formation, it's not the only factor involved. Other processes like tectonic activity and chemical reactions also play a role.
Important Note: While some rocks, like evaporites (rock salt, gypsum), form directly from the evaporation of water driven by the sun, these are still considered sedimentary rocks.
