Formation of Sedimentary Rock Layers

Sedimentary rock layers are formed through the accumulation and compaction of sediments over time. These sediments can include sand, clay, and organic material.

At first, sediments are deposited in layers on the Earth’s surface, often in bodies of water such as rivers, lakes, and oceans. Over time, these layers of sediments are buried and compressed by the weight of additional sediments on top.

The pressure from the overlying sediments causes the lower layers to harden and cement together, forming solid rock. This process, known as lithification, can take millions of years.


The formation of sedimentary rock layers is a slow and gradual process that results in the creation of some of the most common and useful types of rock on the planet.


1. What types of sediments can contribute to the formation of sedimentary rock layers?

Sand, clay, and organic material are common types of sediments that can contribute to the formation of sedimentary rock layers.

2. How long does it take for sedimentary rock layers to form?

The process of lithification, which forms sedimentary rock layers, can take millions of years.

    Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, higher than the highest mountain, flooding, storms, rain, volcanic eruptions, earthquakes and a fiery asteroid bombardment. That planet is surrounded by a gigantic cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So in every layer on our planet we will find material of the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay and meteorites. Even in the youngest, topmost earth layer, which is less than 6,000 years old. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9

    Did you know that flat gaps between rock layers proves that there was in fact a worldwide flood in Noah's day, when God caused it to rain for forty days and forty nights? God used a strong wind to buried the trees and carcasses of man and beast in the earth under great pressure. Genesis 6:17,18
    Genesis 8:1 And God remembered Noah, and every living thing, and all the cattle that was with him in the ark: and God made a wind to pass over the earth, and the waters assuaged.

    Global flood came after, there was water covering the entire earth for ages before dry land appears

    Looks like natural sorting of layers formed under water. What do you do when you date one of the layers out of order…? Shred the theory and make up a new one…?

    it's funny to see how all strata is form by means of water and there is strata all over the globe, yet they deny a global flood. scientist are silly.

    melting ice doesn't form sharp peaks. The moving, frozen glacier carves peaks and turns v-shaped valleys into u-shaped valleys.
