The effects of weathering are best illustrated by natural structures found throughout the world. Types of Weathering With Examples 1. Physical/Mechanical Weathering. Frost Wedging Water, while passing over rock surfaces, can freeze in depressions. The ice thus formed exerts pressure on the rocks, leading to cracks and weathering.

Weathering is the process of the weakening and breakdown of rocks, metals, and manmade objects. There are two main types of weathering: chemical and physical. An example of chemical weathering is acid rain. Caused mostly by the burning of fossil fuels, acid rain is a form of precipitation with high levels of sulfuric acid, which can cause erosion in the materials in which it comes in contact.

Downstream effects of soil erosion include: siltation of watercourses and water storages; reduction in water quality of creeks, rivers and coastal areas. Eroded soil, which can contain nutrients, fertilisers and herbicides or pesticides, can be deposited where there is a reduction in the slope of the land. This can be in sediment traps, along

Abstract. Limiting global mean temperature changes to well below 2 ∘ C likely requires a rapid and largescale deployment of negative emission technologies (NETs). Assessments so far have shown a high potential of biomassbased terrestrial NETs, but only a few assessments have included effects of the commonly found nutrientdeficient soils on biomass production.
