Granite, quartzite areas have upstanding look because – (1) mechanically weathered faster (2) these rocks are resistant to all kinds of erosion (3) these rocks are not easily eroded (4) not easily worn down

Description : Granite, quartzite areas have upstanding look because – (1) mechanically weathered faster (2) these rocks are resistant to all kinds of erosion (3) these rocks are not easily eroded (4) not easily worn down

Last Answer : (4) not easily worn down Explanation: Granite is high in quartz, a mineral very resistant to weathering. Similarly, quartzite is harder than steel.

(3) Detergents give lather even with hard water Explanation: Soaps are made of materials found in nature. Detergents are synthetic a big drawback of washing with soap is that the minerals in water react with those in soap, leaving an insoluble film. Detergents react less to minerals in water and for all practical purposes are the product of choice for laundry, unless you have very soft water. On the other hand, soap will combine with the magnesium and calcium ions in hard water to create an insoluble residue that can clog drains and stick to clothing.
