Study Notes
Atmosphere and Global Wind Patterns
- The atmosphere is composed of various gases with differing abundances.
- Atmospheric layers are defined by temperature gradients, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
- Global wind patterns are driven by intense solar radiation at the equator, density differences, and the Coriolis effect.
- Watersheds are characterized by area, length, slope, soil type, vegetation, and divides with adjacent watersheds.
Sun's Energy and Earth's Surface
- Insolation (incoming solar radiation) is the Earth's primary energy source, varying with season and latitude.
- The angle of sunlight directly influences radiation intensity. The equator receives the most direct sunlight.
- Seasonal variations in solar radiation are dictated by Earth's tilt and its orbit.
- Earth's axial tilt drives seasonal changes and differing daylight hours.
El Niño/La Niña Effects
- El Niño and La Niña are Pacific Ocean phenomena linked to varying ocean surface temperatures.
- These phenomena affect global rainfall, wind patterns, and ocean currents.
Terrestrial Biomes
- Biomes have distinct plant and animal communities adapted to specific climates.
- Major biomes include taiga, temperate rainforests, temperate seasonal forests, tropical rainforests, shrubland, temperate grassland, savanna, desert, and tundra.
- Natural resource distribution (water, timber) depends on climate, geography, latitude, altitude, nutrient availability, and soil characteristics.
- Biome distribution is dynamic and can shift due to global climate changes.
Aquatic Biomes
- Freshwater biomes (streams, rivers, ponds, lakes) are crucial drinking water sources.
- Marine biomes (oceans, coral reefs, marshes, estuaries) are oxygen producers and CO2 absorbers.
- Marine resources (fish) distribution depends on salinity, depth, turbidity, nutrients, and temperature.
Plate Tectonics
- Convergent boundaries form mountains, island arcs, earthquakes, and volcanoes.
- Divergent boundaries create seafloor spreading, rift valleys, volcanoes, and earthquakes.
- Transform boundaries cause earthquakes.
- Plate boundary maps can help predict locations of volcanoes, earthquakes, etc.
- An earthquake arises when stress releases along a locked fault.
Soil Formation
- Soil forms from weathered and transported parent material.
- Soils are categorized by horizons based on composition and organic matter.
- Soil erosion occurs from wind and water.
- Soil protection safeguards water quality through filtration.
Soil Composition and Properties
- Water-holding capacity varies across soil types, impacting land productivity and fertility.
- Soil horizons' size and composition affect soil porosity, permeability, and fertility.
- Several methods assess soil chemical, physical, and biological properties to aid in decisions like irrigation and fertilizer needs.
- A soil texture triangle helps identify and compare soil types.
