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. So, they are not easily worn down and ... and vice versa. So quartzite, though hard and chemically inert, can be fractured by physical weathering.
