Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it’s called shale. Otherwise, it’s siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay).A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Common rocks include granite, basalt... Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.

Sediment can consist of rocks and minerals, as well as the remains of plants and animals. It can be as small as a grain of sand or as large as a boulder. Sediment moves from one place to another through the process of erosion. Erosion is the removal and …A series of sedimentary beds is deposited on an ocean floor. The sediments harden into sedimentary rock. The sedimentary rocks are uplifted and tilted, exposing them above the ocean surface. The tilted beds are eroded by rain, ice, and wind to form an irregular surface. A sea covers the eroded sedimentary rock layers.
