Which statement correctly analyses the risk of high rainfall?

Excess surface runoff can also carry away fertile topsoil and increase soil erosion. Option A is incorrect because heavy rainfall is not always beneficial. Exam tip: While writing effects of rainfall, connect excessive rain with flooding, waterlogging and soil erosion.
