    Study Notes

    Weathering and Erosion

    • Climatic factors play a significant role in the process of weathering.
    • Erosion is the removal and transportation of rock or soil particles from one location to another.
    • Residual or in situ deposits refer to deposits that remain in their original location after weathering.
    • The process that comes after weathering and before deposition is erosion.
    • After weathering and erosion, the rocks and soil particles are transported to a new location and deposited.
    • The primary function of erosion is to shape the land by removing and transporting rocks and soil particles.
    • Weathering contributes to the formation of residual or in situ deposits.
    • Erosion specifically involves the removal and transportation of rock or soil particles from one location to another.
    • Mass Wasting is a process that occurs when there is a sudden movement of rock or soil down a slope.
    • Transportation is a stage that comes after erosion, where the rocks and soil particles are transported to a new location.

    Rock Types

    • Regional metamorphic rocks have a non-foliated or foliated texture.
    • Igneous rocks are products of solidification of molten material from the earth's depth.
    • Coarse-grained and rough rocks are characteristic of intrusive igneous rocks.
    • Fine-grained and smooth rocks are characteristic of extrusive igneous rocks, which are formed from lava.

    Metamorphic Rocks

    • High-grade metamorphic rocks subjected to more temperature and pressure with increasing depth can partially melt to form new magma.
    • Regional metamorphic rocks originate from pre-existing rocks, such as shale or basalt.

    Course Information

    • The field of study of GES 111 is Physical Geology.
    • GES 111 Physical Geology is powered by the University of Nigeria.
    • GES 111 Physical Geology is instructed by Dr. A. O. Eze.
    • GES 111 Physical Geology is a course specifically designed for students from the Departments of Geology, Geography, and Environmental Science.

    Organic Chemistry

    • The product of the cleavage reaction when dialkyl ethers are heated with strong acids is an alkyl halide and an alcohol.
    • A 1° alkyl group tends to undergo SN2 displacement in the cleavage reaction of ethers.
    • When excess HBr is used in the cleavage reaction of ethers, it leads to the formation of alkyl bromides.
    • A 3° alkyl group tends to undergo SN1 displacement in the cleavage reaction of ethers.
    • The cleavage of ethers with strong acids can proceed by an SN1 or SN2 mechanism, depending on conditions and ether structure.
    • The IUPAC name for C2H5OC2H5 is ethoxyethane.
    • The best synthesis method for a 1° halide is the Williamson ether synthesis.
    • Methyl ether is a gas at room temperature.
    • Ethers have a lower boiling point than isomeric alcohols due to weaker intermolecular forces.
    • Ethers are less soluble in water than isomeric alcohols due to weaker hydrogen bonding.
