Aquifers and Mass Wasting
Factors considered when identifying potential aquifers
Depth to water table: Water table refers to that depth below the earth's surface below which there is permanent availability of water. Potential aquifers are mostly located in the region where the water table is relatively closer to the surface of the earth.
Presence of highly permeable soils: Permeability of the soil influences the ability of rainwater or rather surface water to infiltrate into the lower layers of the earth. A region whose soil is permeable is most likely to have critical aquifers. On the other hand, a region with impermeable soil limits water into infiltration to form aquifers.
Presence of flat terrain: Terrain refers to the degree at which the land slopes. Surfaces with flat terrain discourage surface run-off and instead enhances water infiltration into the lower layers of the earth. As a result, the aquifer formed is critical in the sense that it permits its recharge.
Presence of a permanent river: this serves as a supply of water to the aquifer during both...
The following are some of those factors that should be avoided.
Avoided those areas that are potentially polluted (toxins and heavy metal) by industrial waste as well as dumping from human activities.
Areas characterized by intensive agricultural activities should also be avoided. This is because of the high levels of salinity and pesticides used in such activities can percolate into the aquifer making it unsuitable for human use.
Areas close to the ocean, fault lines, and those containing high proportions of clay must equally be avoided. Such areas tend to have high degrees of salt conditions that are not appropriate for human conditions.
How climate influences mass wasting
Mass wasting refers to downward movement of materials under the influence of gravity. Climate is one of the factors…

Weathering is a process that happens to surface rocks based on the particular environment in which the rock is located. The two types of weathering are physical and chemical. Chemical weather is a process in which the internal crystals of rocks undergo chemical changes based on environmental conditions. If rock is exposed to water over a long period of time, for instance, it breaks down and often sand and clay
Weathering and erosion are similar processes that occur over time, impacting the nature and appearance of landscapes. The two processes both affect rocks. Erosion is defined by the movement of air, water, or ice on rock formations, or on the force of gravity on rocks as in landslides. On the other hand, weathering simply breaks down or even chemically changes the composition of rocks without necessarily moving them. Weathering and
Planning and Reflection During my student teaching experiences I kept a journal, which greatly helped me to organize my thoughts and clarify the areas in which I most needed to improve. My mentor also pointed out for me the key areas that need improvement. Therefore, as I look forward to a professional career as a teacher, I will be able to draw on these early experiences. I will remember what works
LANDFORMS Barrier island beaches generally develop where: a The coast is composed of hard rock b the nearby land has a rugged topography of hills and mountains c the sea floor deepens rapidly offshore d The sea floor remains shallow for a long distance offshore During storms in winter: a There is a higher percentage of fine-grained sand on beaches b More erosion occurs in bays than on headlands c Beaches are eroded d Beaches are
ASEAN The study will be delving into: What ASEAN constitutes and what remains beyond its scope? The aim of this study will be handing out a wide-ranging presentation of the present stance of ASEAN and its accomplishments till date, along with its challenges. The paper is intended as a suggestion for a master-plan that can be employed as a future pathway where ASEAN political-security support must be going towards in
Both, ironically, are forms of pressure that also cause heat and changes. Water for instance, is so abundant on earth that it drives much of weathering and erosion. Precipitation, acidic soil water and groundwater dissolve mineral and rocks; serpentinization from heated seawater causes destruction of volcanic rock or changes in other seabed rocks; and the presence of water and carbon dioxide change rock as well. This is the manner
