Explanation:
Here is the explanation about these layers.
Limestone: This rock is formed from sediments that gather on the river floor over time & Limestone is mostly found in rivers, caves, etc. This resource is made from natural activity, for example, sediments travelling through the river & the water causing it to settle.
Banded-iron formations: This rock, or resource, is thought to be made in the seawater millions of years ago and is the result of oxygen production from a particular type of photosynthetic cyanobacteria. The oxygen, combined with dissolved iron makes this resource.
A metamorphic rock with fine grains: I cannot explain how this rock is made from, please find someone who can.
Red Beds: "Red beds may form during diagenesis. The key to this mechanism is the intrastriatal alteration of ferromagnesian silicates by oxygenated groundwaters during burial. " - Wikipedia
Chert Layers: Chert can form when microcrystals of silicon dioxide grow within soft sediments that will become limestone or chalk.
I hope this has helped you to learn about these rocks.

Answer:
The general pattern in changes in the layers of soil with depth is called <u>Soil Horizon</u>
Explanation:
The layer of soil present parallel to the surface, having different chemical physical and biological properties from the layers that are present above and below it, is known as the soil horizon.
The difference in the properties of the layers of soil can be the texture of the soil, color of the soil, particle size of the soil etc.
The Sun causes tides just like the moon does, although they are somewhat smaller.
The Earth gets an equal amount of light from the sun and moon
In our solar system, Earth is the third planet from the Sun.
