    Study Notes

    Seismic waves

    • S waves travel only through solid materials
    • P waves travel through solid, liquid and gaseous materials

    Earth's Structure

    • Earth's core is made up of nickel and iron
    • Oceanic crust is thinner than continental crust
    • The upper portion of the mantle is called the asthenosphere
    • The inner core is solid while the outer core is liquid
    • The lithosphere is made up of the crust and upper mantle

    Rocks

    • Igneous rocks are formed when magma or lava cools and solidifies
    • Metamorphic rocks are formed under the action of pressure, volume, and temperature
    • Quartz can be white, green, red, or yellow due to impurities
    • The Mohs Hardness Scale measures the resistance of minerals to scratching
    • The order of hardness for the minerals listed is: Talc (1), Gypsum (2), Feldspar (3), and Diamond (4)
    • Sedimentary rocks are formed through the process of lithification.
    • Geyserite, chalk, and shale are all organically formed rocks
    • Sandstone is a chemically formed rock
    • Granite is primarily made up of silica and aluminum
    • Marble is a metamorphic rock
    • Sandstone, conglomerate, and limestone are examples of sedimentary rocks
    • Syenite, slate, and schist are examples of metamorphic rocks
    • Sedimentary rocks are characterized by layers of varying thicknesses

    Plate Tectonics

    • Orogenic processes involve mountain building
    • Epeirogenic processes involve uplift or warping of large parts of the Earth's crust
    • Plate tectonics involves the horizontal movement of crustal plates
    • The supercontinent Pangaea was surrounded by a single ocean called Panthalassa
    • The Cocos plate exists between Central America and the Pacific plate
    • The Nazca plate exists between the Asiatic and Pacific plate
    • The Arabian plate primarily covers the Saudi Arabian landmass
    • The Himalayan mountains are formed by a continent-continent convergence boundary between the Indian plate and the Eurasian plate
    • The Mid-Atlantic Ridge is formed by a divergent plate boundary

    Landforms

    • The Polar fleeing force is related to the rotation of the Earth
    • The Pacific plate is primarily oceanic
    • The Eurasian plate is primarily continental
    • The Arabian plate, Pacific plate, Antarctica plate, and Eurasian plate are all major plates
    • Youth stage landforms are dominated by downward cutting
    • Gorges are deep valleys with steep sides
    • Canyons have steep, step-like side slopes
    • A gorge is wider at the top than the bottom
    • A canyon's width is relatively consistent
    • Gullies, rills, gorges, and canyons are formed by running water
    • Lapies are irregular surfaces with sharp pinnacles, grooves, and ridges
    • Alluvial fans in humid areas have gentle slopes, while those in arid areas have steep slopes
    • Natural levees are found along the banks of large rivers
    • Meanders are landforms formed by running water
    • Point bars, or meander bars, are found on the concave side of a river's meander
    • Stalagmites rise up from the floor of caves
    • Caves, bars, spits, and beaches are all erosional features
    • Cirques are deep, long, and wide troughs or basins with steep concave walls
    • Drumlins are smooth oval-shaped ridge-like features composed of glacial till
    • Playas are salt lakes
    • Barchans are crescent-shaped dunes
    • Wind causes deflation, abrasion, and attrition

    Atmosphere

    • Water vapor content in the atmosphere decreases from the equator to the poles
    • Dust particle concentration is higher in equatorial and polar regions than in subtropical and temperate regions
    • Air density is highest near the Earth's surface and decreases with altitude
    • The Coriolis force deflects winds to the right in the northern hemisphere and to the left in the southern hemisphere
    • The Intertropical Convergence Zone (ITCZ) is where the trade winds from either side of the equator converge
    • An occluded front occurs when an air mass is fully lifted above the land surface.

    Weather

    • A cold front forms when a cold air mass moves towards a warm air mass
    • A warm front forms when warm air moves towards a cold air mass
    • A tropical storm requires a large sea surface with temperatures greater than 27°C, the Coriolis force, and small variations in vertical wind speed
    • Cirrus clouds are formed at high altitudes (8,000-12,000 m)
    • Stratus clouds are layered clouds that cover large portions of the sky

    Oceans

    • The Labrador Current is a cold current in the North Atlantic Ocean.
    • The Falkland Current is a warm current that flows along the Chilean coast of the South Pacific Ocean
    • Dew forms under clear skies, calm air, high relative humidity, and cold nights
    • The dew point must be above the freezing point for dew to form
    • Fog and mist are both forms of condensation, but fog has a higher moisture content
    • Seamounts, mid-oceanic ridges, and submarine canyons are all minor relief features in the ocean

    Tides

    • Spring tides occur when the Sun and Moon pull the Earth gravitationally in the same direction
    • Two high tides and two low tides occur each day, known as a semi-diurnal tide
    • The Moon is closest to Earth at perigee

    Solar System

    • The inner planets are those located between the Sun and the asteroid belt
    • Eons are the longest units of geological time

    Human Geography

    • The concept of human development was introduced by Dr. Mahbub-ul-Haq
