Gravel areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or tarmac; Russia alone has over of gravel roads. Both sand and small gravel are also important for the manufacture of concrete. Large gravel deposits are a common geological feature, being formed as a result of the weathering and erosion of rocks. The action of rivers and waves tends to pile up gravel in large accumulations. This can sometimes result in gravel becoming compacted and lithified into the sedimentary rock called conglomerate. Where natural gravel deposits are insufficient for human purposes, gravel is
Granular cheese cheese. Granular cheese for manufacturing must meet all of these standards except that it does not need to be cured, nor do the dairy ingredients used need to be pasteurized. This is the type of granular cheese most commonly used for processing. Although granular cheese can be created using any method that achieves the designated standard for physical and chemical properties, there is one method that is generally used. First, the milk or cream may be warmed and treated with hydrogen peroxide and catalase, producing water and oxygen gas. Then, a lactic acid-producing bacterial culture is added, and the product
