Chemical weathering and mechanical weathering can be influenced by plants. Plants contribute to mechanical weathering when their roots growth through cracks and crevasses in soil or rock. Overtime the roots will break rocks apart. Some plants produce and secrete organic acids that can change the chemical composition of rocks causing them to weather. Mechanical weathering breaks rocks into smaller pieces while chemical weathering changes the composition of the rocks.

Answer
<u>A rapid improvement in standard of living can mean rapid economic growth with increased population in towns resulting to damaged environment in form of pollution.</u>
Explanation
When the standard of living is associated with rapid growth of the economy, a common scenario is migration of people to urban areas to work and operate businesses. The urban areas will experience increased populations with inadequate housing. The environment will be suppressed because more forests will be cleared to give out spaces for new housing projects. In addition to that, the pollution levels will increase because more wastes will be generated.
