Groundwater . a) an abrupt change is the composition of the sediment It fills the pores and fractures in underground materials such as sand, gravel, and other rock, much the same way that water fills a sponge. a) very coarse granite pegmatite Yes, water below your feet is moving all the time, but not like rivers flowing below ground. Groundwater moves very slowly through relatively impermeable materials such as clay and shale. a) spring water The amount of water a material can hold is directly related to the porosity since water will try and fill the empty spaces in a material. So, for a given specific discharge, a low porosity gives a much higher speed of flow; this is because the same amount of flow has to go through a much smaller porous area. d) dissolving some parts of the rock and carrying the material away Lecture notes Dr. J.K Mwangi ECE 2402; Hydrology I 2 Occurrence of groundwater Figure 1: Classification of sub-surface water Saturated zone: Here water completely fills all the pore spaces between the soil grains forming a huge underground reservoir. a) sunlight and photosynthesis holds exclusive rights to this article under a publishing agreement with the author(s) or . b) reverse b) surface waves d) conducting seismic surveys to investigate rock layers d) cool air rising from the equator and flowing east and west a) effervescence Shasta b) past changes in climate This is referred to as secondary porosity, to distinguish it from the intergranular, or primary, porosity. b) 100 meters Porosity is the percentage of void space in a rock. b) volcanic eruptions d) in a subduction zone or accretionary prism, sudden movement of a fault can cause a tsunami when: After dissolution, porosity was greater than before dissolution, increasing by 0.140%, 0.038%, 0.042%, and 0.126%, respectively .

Groundwater flows at right angles to the equipotential lines in the same way that water flowing down a slope would flow at right angles to the contour lines. a) metallic bond Porosity is the percent of open spaces or voids within a volume of soil or rock. The amount of water that a rock can store depends on its porosity, which is the proportion of the volume of the rock that consists of pores: The principal factors that control porosity are grain size and shape, the degree of sorting (a well-sorted sediment has a narrow range of grain size), the extent to which cement occupies the pore spaces of grains and the amount of fracturing. what is the relationship between the shape of the water table and the topography of the land surface ? b) an increase in snow cover causes the atmosphere to heat up whcih causes more evaporation a) mid-ocean ridges e) metamorphism, A rock is subjected to differential stress, then it means that: b) the amount of sediment in rivers c) a transform fault to a subduction zone 2. forms cone of depression The amount of water a material can hold is directly related to the porosity since water will try and fill the empty spaces in a material. d) water cannot erode unless it is carrying sediment For example, to determine the effective porosity of a granular earth material, a sample volume is collected, allowed to dry completely, and then water is introduced slowly to the base of the sample (so that air can escape from the top).
