Sand is deposited as single touching rigid grains. The
porosity
is the space remaining between the touching grains, and is not reduced significantly by compaction until pressures cause the sand grains to break or to undergo chemical changes such as diagenesis. In diagenesis the sand grains will dissolve and redeposit changing the volume and porosity of the sandstone.
Mud can have 60-80% original porosity, before compaction while sand porosity is normally below 45-50% when originally deposited. The reason mud is so different is that it has an open fabric that can hold water within the mud floccules, which are groups of clay platelets held together by
ionic attraction
(and not gravity). Clay platelets in the mud form a "house of cards" type structure due to the ionic attraction between them and create this open system that can hold more water than mud initially.
Mud particles are generally smaller and more capable of rearranging themselves into denser packings during compaction. This results in a higher reduction in volume compared to sands, which have larger and less mobile particles that can't rearrange as easily. Additionally, mud may contain more water, which can be expelled during compaction, contributing to the volume loss.

When saturated soil is shaken during an earthquake it may lose its strength this phenomenon is known as?
liquefaction. During liquefaction, the water-saturated soil behaves like a liquid due to increased pore water pressure, resulting in loss of strength and stability. This process can lead to ground failure, settlement, and potential structural damage during an earthquake.
How can soil lose its value?
Soil can lose its value through erosion, pollution, compaction, and depletion of nutrients. Erosion can wash away topsoil, which is rich in nutrients necessary for plant growth. Pollution from chemicals or heavy metals can contaminate the soil and render it unsuitable for agriculture. Compaction can reduce soil porosity and water infiltration, affecting plant growth. Depletion of nutrients can occur from overuse or improper farming practices, resulting in poor soil fertility.
What ways could soil losse its fertility?
Soil can lose its fertility due to erosion, leaching of nutrients, depletion of organic matter, compaction, and contamination with pollutants or chemicals. These factors can reduce soil health and productivity over time.
Liquefaction is likely to occur when the soil is filled with?
Liquefaction is likely to occur when the soil is filled with loose, saturated, granular materials such as sands and silts, with high water content. The excess water reduces the friction between soil particles, causing the soil to lose its strength and behave like a liquid during an earthquake or other intense shaking event.
The volume of air in a balloon decreases as soon as it is taken out of the warm store and into the cold air This is due to?
The decrease in volume of the air inside the balloon is due to the decrease in temperature. As the air inside the balloon cools down, its particles lose kinetic energy and move closer together, resulting in a decrease in volume. This phenomenon is described by the ideal gas law, where volume is inversely proportional to temperature when pressure is constant.

Does matter lose mass when it changes space?
If by space you are referring to volume, then NO. Matter doesn't lose a considerable amount of mass when it changes volume. See: Law of Conservation of Mass. However, if the volume increases and the mass does not the density of the object decreases. Summary: No. It doesn't lose mass. But it does lose density.
Can you lose your appetite during your period?
You will have lose of appetite.
Do you lose urinary volume during heat stroke?
Yes and no. Dehydration is usually comorbid with (occurring alongside) heat stroke. One result of dehydration is reduced urine volume so, while a patient displaying symptoms of heat stroke will likely have reduced volume, it's not from the heat stroke itself.

What is the problem of tv volume continues loud?
if you watch television with the volume to loud [you may lose your hearing] you can go deaf for life.
Do refined foods lose nutrients during processing?
Refined foods may lose many nutrients during processing.
If you melt an ice cube will the volume be the same?
Nope, you lose about 9% of volume when ice melts. That's because when you freeze water, it expands. It loses volume if you do it the other way around.
If you eat fruit and water everyday will you lose weight?
It depends on the type and volume of fruit.
