Describe the relationship between global climate change and rock weathering Draw a typical toil profile. What Is the difference between weathering and erosion? Can you relate the two in a formula? List and describe the mechanisms by which rocks are (a) physically weathered and (b) chemically weathered. Draw a typical soil profile, What three general factors govern the physical properties of sod? What three factors are used to classify a soil in the USC system? Define each of the following symbols as used in the Unified Soil Classification: How is the consistency of a soil measured for pyrotechnical purposes? To an engineer, what is meant by "ground conditions"? To an engineer, what is meant by "rockhead*? Is this surface always well defined? What is a practical definition of rock (vs soil) for an engineer? Comparing residual to transported soils, which tends to have the greatest variations in engineering index properties (IE physical properties) with depth? What was the transportation agent for each of the following transported soils? (a) terminal moraines (b) sand dunes (c) loess (d) alluvium (e) colluviums Describe the landslide risk of each of the following. (a) A very large sand dune (b) A 5-m high vertical cut in losses (c) A cut in a shale deposit that clips toward the cut Describe the geological sediments formed by weathering of the following rock types: (a) granite (b) basalt (c) Sandstone (d) siltstone (e) shale (f) limestone Describe the engineering classification of weathered rock (Grade I to Grade VI)

Explanation / Answer

the rock weathering will leads to the cooling of global climate.

the silicate rock weathering is mainly done by the carbonic acid which is formed by the reaction of atmospheric carbon with the rain water. so for the weathering to occur at greater rates, more cabon dioxide has to be removed from atmosphere. since co2 is a green house gas, the decreased amount of co2 in atmosphere will leads to glbal cooling
