In which type of soil would you expect to see most bubbles when water is mixed with the soil sample?
clay soil
What substance found in a soil sample collected in an arid region would most likely be absent in a soil sample collected in a humid region?
rock salt
Is a typical soil sample an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.A homogenous mixture means that all components of the mixture are equally distributed throughout the entire mixture. Soil, then, would not be a homogenous mixture. Every time one takes a sample of a soil mixture and analyzed it, it would have a different make-up then other samples taken from the soil mixture. One would seldom be able to get two samples that had the same make-up.No, soil is heterogeneous.No. A mixed sample, by Nature, is heterogenous and so may not also be a homogenous (pure) substance.
What are the advantages of conducting an experiment on undisturbed soil sample compared to disturbed soil sample?
A disturbed sample is one in which the structure of the soil has been changed sufficiently that tests of structural properties of the soil will not be representative of in-situ conditions, and only properties of the soil grains (e.g., grain size distribution, Atterberg limits, and possibly the water content) can be accurately determined. An undisturbed sample is one where the condition of the soil in the sample is close enough to the conditions of the soil in-situ to allow tests of structural properties of the soil to be used to approximate the properties of the soil in-situ.
What is the general appearance of the soil sample?
Brown.
How would soil sample be described?
Crumbly, bits of earth.
In which type of soil would you expect to see most bubbles when water is mixed with the soil sample?
clay soil
How would you find the mass of a sample of soil?
With a precision balance.

No, a typical soil sample is heterogeneous.
A scientist studying humus would most likely examine a sample of what?
Soil
Would a soil sample from a temperate deciduous forest be more or less nutrient - rich than a soil sample from a tropical rain forest?
A sample of soil from a temperate deciduous forest would be less nutrient-rich than the soil from a tropical rain forest, because the moisture would continually break down mulch to support a bigger variety of organisms.Tropical rain forests naturally support more species than a deciduous forest too.

A disturbed sample is one in which the structure of the soil has been changed sufficiently that tests of structural properties of the soil will not be representative of in-situ conditions, and only properties of the soil grains (e.g., grain size distribution, Atterberg limits, and possibly the water content) can be accurately determined.

How can porosity be measured?
Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.
What is the best speed to separate a soil sample in a centrifuge?
Very high speed is the best speed to separate a soil sample in a centrifuge.
How do you neutralize soil after fertilized?
To neutralise a sample of soil, you must determine the pH of the soil sample either acidic or alkaline. Add lime (e.g. Limestone) to acidic soil to neutralise it. And add sulphur to alkaline soil which will neutralise it.
