Economics of scale can be internal to an organization (cost reduction due to technological and management factors) or external (cost reduction due to the effect of technology in an industry). See also diseconomies of scale. Use economies of scale in a sentence. Big companies are often more profitable than smaller ones because of economies of scale: suppliers may offer discounts for larger orders, shippers may decrease per trip costs to compete for a large volume of business, and necessary production management staff may increase internal manufacturing efficiency.
Weathering describes the means by which soil, rocks and minerals are changed by physical and chemical processes into other soil components. Weathering is an integral part of soil development. Depending on the soil-forming factors in an area, weathering may proceed rapidly over a decade or slowly over millions of years.
Rock Cycle: The Marriage of Water and Rock. Everything in the Biosphere is part of one system, so Rock Cycles could be discussed under Circles as well as under Biosphere. The Water Cycle and the Rock Cycle are closely interlinked, as if they were partners in a long marriage. Everything really is connected to everything else. The creation and movement of rock around the earth is the rock cycle. It is a very slow process that happens over millions and millions of years. People have been finding fossils of ocean creatures high up in the mountains for hundreds of years. How they got there was once a great mystery of science.
