Mos flat rocks are sedimentary, with shale being a prime example. Shale forms from fine sediment being laid down in layers and then later hardened into rock, with the layers preserved. Slate is a metamorphic rock derived from shale that still preserves the layering.
Wear on the rock, like for example in a river there are a lot of smooth pebbles because the water flowing by smooths the surface
You need rocks and a flat land
Are meatmorphic rocks and also perhaps soil.
All rocks can form from sedimentary because the rock cycle is endless.
igneous rocks form within earths surface
Rocks with grains that lie in flat layers are sedimentary rocks, which include sandstone and shale. Rocks with swirling patterns are often metamorphic rocks, such as gneiss or marble, which have undergone intense heat and pressure causing their minerals to align in distinct patterns.
The description you provided is a characteristic of foliated rocks, such as slate or schist. These rocks have grains that align in flat layers due to pressure and heat during formation, giving them a layered or swirled appearance.
A flat deposit of rocks is called a flagstone. Flagstones are commonly used in landscaping and exterior walkways due to their flat, durable surface.
Flat layers that may become tilted over time
Sedimentary rocks have flat layers.
Some rocks are flat because they were formed through processes like sedimentation or metamorphism, which can result in layers of sediment or minerals being compressed into flat planes. Additionally, erosion and weathering can also contribute to shaping rocks into flat surfaces over time.
The thin flat layering found in most metamorphic rocks is called foliation
Metamorphic rocks can form from both igneous and sedimentary rocks
