Porosity or permeability .
erosion
The process of removing rock particles by wind, water or ice is called erosion. This can also be the removal of enamel from teeth by acid (acid erosion). To be more precise, this is weathering process of the rock where in the rock is broken into small particles by natural forces like wind, water, ice or gravity to get it eroded.
Erosion
Mechanical weathering.
exfoliation
it is called hi there
Porosity or permeability .
1. Grinding of the rock salt. 2. Dissolving of the rock salt in water. 3. Filtering of the solution. 4. Repeated processes of crystallization/recrystallization.
chemicals and wether
it says at the back of the fiji bottle after filtering through volcanic rock our water collected in an artesian aquifier deep within the earth this natural process added silica a mineral that contributes to fiji waters unique soft mouthfeel:)
Weathering.
Table salt is refined rock salt; shortly the process is: - grinding of rock salt - dissolving in water - filtering - purification by repeated processes of crystallization/recrystallization - adding iodine (as potassium iodate or iodide) and an anticaking agent Some sources of rock salt are practically pure and doesn't need to be refined.
Water can flow into cracks in the rock, then freeze, expand, and crack the rock. This is part of the erosion process.
Water and wind are the primary weathering forces. There can also be some erosion by rock-to-rock contact, knocking pieces of the schist apart (can't remember the name for this process.
weathering
A simple method involve filtering of the water solution and refining by repeated processes of crystallization/recrystallization.
