stratification

Stratification is the separation of things into layers. You can see stratification in many different places, such as in sedimentary rocks, soil, and even the atmosphere.

In sedimentary rocks, stratification is caused by the deposition of sediment over time. The sediment is deposited in layers, and each layer is made up of different materials. The layers can be different colours, textures, or thicknesses.

In soil, stratification is caused by the accumulation of organic matter and minerals. The organic matter is decomposed plant and animal matter. The minerals come from the rocks that the soil is made up of. The layers of soil can be different colours, textures, or depths.

In the atmosphere, stratification is caused by the temperature of the air. The air is warmer near the ground and cooler at higher altitudes. This causes the air to be stratified into layers, with each layer having a different temperature.

The stratification of the sedimentary rocks can be seen in the cliff face.
