Briefly explain how time affects characteristics of soil?
Answers
Answer:
Time is the fifth factor in soil formation. Over time, vegetation and climate act on parent material and topography. Development, not chronological age, determines a soil's age. The degree of aging depends on the intensity of the other four soil-forming factors.
Explanation:
How can time affect soil?
Time is one of the factors of soil formation (the other factors are climate, organisms, topography, and parent material). As soils age, minerals change from one form to another, chemical compounds and clays are carried downward through the soil profile, and organic matter accumulates. The older a soil is, the more time it has to develop.
Here’s a young soil, shortly after the sediment has been deposited by water or wind:
Thousands of years later, usually in cool, moist, forested environments, it might look like this:
After thousands of years in a warm, moist environment:
Or thousands of years under grassland vegetation:
Without time, soils would be a rather bland pile of mineral grains. With time, they progressively develop their own, unique personalities.
How does time contribute to soil formation?
What are the role of time in formation of soil?
Why does soil change with time?
How does time determine soil type?
How long does it take for soil to form?
Positivey, time enable the soil to develop it's physical and chemical properties well.
Negatively, time expose the soil to the agent of erosion and other destructive agents like the sunlight which lead to the increase in soil pH.
That's a very short summary.
As usual time does nothing. If you have just time nothing happen everything stay as it is. But if you see transformation and changing you will say: “oh time is doing something” but time is doing nothing not even passing through. If, if you want to learn more about time concept you can read this ebook. “sorry only in french up to now)
Time does not effect the soil. Time does effect the rate of microbial action in the soil. It also allows organic mater to decompose.
So to phrase the question different time is the natural measure that tells you how long each and every Micro system takes to live and complete their life cycle. The dirt devoid if the micro life is still soil but would still be the same 1000 years from now.
So time does effect the soil Colony and for the most part in a positive matter. Time is important to the soil to be able to utilize the cycles for our betterment.

What does 'activity' of soil mean?
Activity(A) is ratio of Plasticity index to the % of clay fraction
Amount of water present(holding capacity) in soil depend upon type of clay mineral.
Activity measure water Holding capacity of soil.
Swelling and Shrinkage(Volume changes) properties of soil depend upon Activity.
Montmorillonite (A>4) high Activity
illite (A=1 to 2)Medium Activity
Kaolinite (A<1) low activity.
ACTIVITY IS GIVES INFORMATION ABOUT TYPE OF MINERAL AND ITS EFFECT IN SOIL.
How long does it take soil to replenish itself?
Soil doesn’t regenerate in any predictable way. It can become more fertile, remain the same, or even lose constituent parts that make it fertile, depending on climate and conditions. In the past, locals here in the Florida Panhandle would tell you with certainty that “topsoil” regenerates at a rate of 1 inch per 100 years…but that means something is being added to, or removed from the soil in a regular, predictable manner, meaning there has to be a continuous source, and that no outside forces like erosion are depleting the soil during that time span.
While the question isn’t specific to buildi
How will climatic condition affect the soil of a place?
Climate affects soil formation because it determines the amount of water that is available for processes such as the weathering of minerals, the transportation of minerals and the release of elements. Climate also influences the temperature of the soil, which determines the rate of chemical weathering.
The decomposition of organic matter is also accelerated in this type of climate. Climates that are cold and dry have an opposite effect on plant growth and decomposition.
The figure shows how the climatic conditions at different places affect the soil formation and then the development of soil at
Why does soil change with time?
Soil formation depends on many factors such as the parent rock material, climatic conditions, biotic action, etc. Time is also one of the factors for soil formation. It is also a very important factor.
Unlike other factors which play a more active role in the formation of soil, time plays a more passive role.
Any soil that is formed anywhere in this world due to any of the major factors cannot have formed if there was a lack of time. Soil formation requires considerable amount of time and hence soil formation is.
What are the role of time in formation of soil?
Time is one of the five main factors of soil formation. The other four are parent material, climate, topography, and biological activity. It is not entirely possible to separate the effect of time from these other four, but let’s consider two soils that are as alike as possible except for age.
