One important relationship between chemical and mechanical weathering is . 1. mechanical weathering forms more brittle materials that are easily broken down by chemical weathering.2. mechanical weathering can produce smaller pieces of rock that have more surface area for chemical weathering to work on. 3. chemical weathering can produce smaller pieces of rock that can then be modified by mechanical weathering 4. chemical weathering can form brittle materials that are easily broken into smaller pieces by mechanical weathering

2. mechanical weathering can produce smaller pieces of rock that have more surface area for chemical weathering to work Explanation:

Mechanical weathering involves activities of living organisms or some geological processes. The bigger rocks are usually reduced to smaller rocks and further reduction might be limited or not posibble mechanically. This reduced rocks now increases the surface area available for chemical weathering; which further reduces the sizes of the rocks below the size range of mechanical weathering. one will recall that the rate of chemical reaction increases with exposed surface area.
