Assuming that you are referring to a naturally deposited layer of soil, it would suggest that there has been a change in the depositional environment from a low energy to a high energy one.
For example in periods of dry weather with little rainfall, rivers can begin to dry up. The flow of water will be slow and there may even be "stagnant" pools where the water barely flows at all. These are "low energy" environments and the water is not able to carry sediment very effectively so even the very fine material such as clay will settle out of the water.
As the climate eventually becomes wetter, there will be more water in the river and the speed or flow velocity of the water will increase. This is an example a higher energy environment. As such the water is easily able to carry the very fine sediment but may still be unable to transport larger grain sizes such as sand which will be deposited over the location where the clay sized particles were originally deposited.
This cycle may continue over a number of years leading to alternating layers of finer and courser material.

What are the different types of sediment that make up soil?
the different types of sediment that make up soils are gravel, sand, clay, and silt.
What are two different sediment type examples?
* Clay * Silt * Sand * Pebbles * Cobbles * Boulders * Gravel
How are sediments created?
when a granite rock weathers andit turns to sand or clay also called sediment.
Which inorganic sedimentary rock has the smallest size sediments?
the smallest particles of sediment are found in clay.
Why is river water a solution?
why river water solutioncarries sand,clay and other sediment :) i am sure it is correct because i got it right in homework :)
Name the sediment that has particles that are larger than clay but finer than sand?
silt
Which type of sediment would undergo more compaction grains of sand or grains of clay?
Grains of clay due to their flat structure.
What are the different types of sediment that make up soil?
the different types of sediment that make up soils are gravel, sand, clay, and silt.
What are ice age varves?
Varves are glacial lake deposits, usually an annual sediment of thick pale sediment denoting summer deposition when some ice melted and left silt and sand to settle in a lake, and a thin, dark layer of clay for a winter deposit when little sediment entered the lake.
What is the correct order of sediment in these materials from smaller particles to bigger particles?
clay,sit,sand
How does loess deposit form?
Loess deposits is form when sediment that is finer than sand, such as particles of clay and silt, is deposited into layers far from its source.
What are two different sediment type examples?
* Clay * Silt * Sand * Pebbles * Cobbles * Boulders * Gravel
How are sediments created?
when a granite rock weathers andit turns to sand or clay also called sediment.
What is the correct order of sediment size in these materials from smaller particles to bigger particles?
clay,sit,sand
What is the detrital sediment sizes in order from smallest to largest?
Clay, Silt, Sand, Granule, Pebble, Cobble and Boulder.
Which inorganic sedimentary rock has the smallest size sediments?
the smallest particles of sediment are found in clay.
What is the order of sedimentary settling?
Sorting is the degree of uniformity of grain size of a rock
