OUTLINE ANSWERS WITH BULLETS AND/OR 1-20. How can lakes exist at elevations above the groundwater table? 1-22 Why are naturally filled-in lake locations often thought of as areas that offer poor support for building foundations? 1-24. In glacially affected areas, what types of glacial deposit:s are possible good sources of sand and gravel for the construction industry? 1-28 a. Briefly explain the geological differences between a transported soil and a residual soil deposit and climatic conditions are deposits? and climatic conditions are formations? b. What combination of geographic, geologic, topographic associated with, or responsible for, transported soil c. What combination of geographic, geologic, topographic associated with the presence of residual soil 1-29. Formations of residual soil typically have strength-related characteristics distinctly different from deposits of transported soils. Briefly describe the significant differences.Explanation / Answer
Answer:
1-20:
Lakes, sometimes, happen uniform at promotions above the groundwater table. Such conditions arise when watercourses of water flow into a basin area where the ground is rather impervious. The impervious earth prevents the water from permeating and mixing with the groundwater. Therefore, the water gets collected and forms lakes.
1-22:
The soils at positions of filled-in lakes are mostly collected of fine-grained silt and clay. These
particles were placed in the central regions of the lakes after the waters calmed down, such
as during terms of low inflow, because of which, the soil cover was built up by alternative
layers of these particles. These layers remained weak and compressible if no stresses, such as
overlying glaciers, acted upon them. Consequently, these lakes form sites that offer poor
support for building foundations.
