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
- Truck farming is a specialized form of agriculture that focuses on vegetables
- India's population experienced negative growth rate from 1911-1921
- The Bora is a cold and dry wind that blows down from the mountains in the region of the eastern shore of the Adriatic Sea
