GEOLOGY

Detailed explanation-1: -Striped patterns in stones are usually caused by layers of sediment that have accumulated over time.

Detailed explanation-2: -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.

Detailed explanation-3: -Foliated Metamorphic Rocks: Some kinds of metamorphic rocks–granite gneiss and biotite schist are two examples–are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.)

Detailed explanation-4: -Key points: Sedimentary rocks typically occur in horizontal layers called strata. In undisturbed strata, younger layers sit on top of older ones. This is known as the law of superposition. Strata can be cut by other geologic features, such as faults or intrusions.
