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.

When saturated soil is shaken during an earthquake it may lose its strength this phenomenon is known as?
For sands it is called "running sand"
Why does the soil lose nitrates during heavy rain or flooding?
nitrates are soluable therefor become a solution when mixed with water!
What is lithification in geology?
Lithification is the natural creation of sedimentary rock through the processes of compaction and cementation of sediments. The compaction usually occurs as a result of the crushing weight of overlying sediments above, expelling water and air from between the pore spaces of the individual sediment particles. As the water is squeezed out, a form of mineral precipitation occurs and these minute mineral crystal structures attach themselves to, and cement together, the individual particles of sediment, whether they be sand grains, minute clay particles, pebbles, or boulders.
Why is it important to us to identify areas which are prone to earthquakes?
For those zone, We can take action to forecast its coming and then lessen the lose during the earthquake.

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.
What did British do during the revolutionary war?
