- This is what we call stratification; it requires two rocks with different densities (as well as other factors including crustal movement, soil disturbance, and water) and arranges them in layers.
- but before i discuss our main topic im going to explain first how the Stratification form? happen
- The weight of the sediments compressed and compressed the layer into smaller spaces over time, creating compaction.
- Hi everyone today we are going to discuss the step-by-step process of stratification
- But before that it must undergo with three steps and it means it has four steps.
- So now does anyone  here in the classroom know the four steps of stratification
- can anyone give me the number one step of  the four steps of stratification
- Yes miss erica can you give me the first step
- the first step is Weathering
- Weathering doesn't mean weather.It can happen because of abrasion, when water freezesit, root action, heat and there are many ways to breakdown rocks and then next;
- Weathering is breakdown of rocks.By the help of many elements such as wind, water,animals, gravity and heat.
- and for the second step  mr justine
- Pebbles rolled along a riverbed or the seashore, sand grains whipped up by the wind, salts carried in solution all are examples of how sediment is moved.
- After it breaks down into smaller portion, it combinedwith by elements those are water, wind and gravity evenpeople and animals.
- Step 2: Erosion (Transport)
- miss annika for the third step
- For example, a simulation in laboratory, when you putrocks together. Over time it will form a thick layer and itwill settle down.
- Deposition occurs when sediments are broken down into smaller pieces.River beds, ocean floors, and other surfaces are littered with rock fragments.land masses, gathering players
- Compaction is the mechanical process of increasing soil density while removing air. The size of individual soil particles remains intact, and no water is removed
- And finally the last one  Step 4: Compaction
-  The aim of purposeful compaction is to enhance the strength and stiffness of soil.
