Question

A large rock is broken into several smaller pieces. Compared to the rate of weathering of the large rock, the rate of weathering of the smaller pieces is

Answer 1

Greater

Step-by-step explanation:

Large rocks have less surface area for their volume than small rocks.

Therefore, a smaller portion of the rock is exposed to weathering.

It takes longer for the rock to wear away. The small rock has more surface

area for its volume, so it weathers away faster.every time the rock breaks into

smaller pieces its surface area or part exposed to weathering is increased.

Answer 2

Greater

Step-by-step explanation:

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

- Physical weathering is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

- Chemical weathering is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Since the large rock is broken into several smaller pieces. comparing this rate of weathering of the large rock, the rate of weathering of the smaller pieces will be greater.
