Government has a limited amount of budget. If the government choose to allocate that budget to build a school, it will automatically mean that the amount of money that can be used for other programs is reduced. This is why we can consider them as an opportunity cost.
When granite weathers mechanically, it turns into feldspar, mica, and clay
Answer: Option A
<u>Explanation:</u>
Chemical weathering is also popularly known as Mechanical weathering of granite starts when mild carbolic acid mixed with it. Initially, it alters the Feldspar in the hydrolysis process. Thus the reaction results in forming kaolinite, silica in solution and potassium ions as by-products.
Kaolinite is one of the clay mineral layered with silicate and silica by-products consist of mica. As time goes by the Feldspar cools down returning as the same particle in the sand. Moreover in warm regions, the weathering on feldspar forms a high amount of clay along with the red soils.
