Study Notes
Global Systems
- Global systems are complex and interconnected
- Weather refers to atmospheric conditions at a specific time and place
- Climate refers to average weather conditions over many years (at least 30)
- Evidence can be anecdotal (personal experiences) or scientific (data and measurements)
- Different climates can be classified as narrow (not varying much), moderate (mild), or wide (large variations)
The Biosphere
- The biosphere is the narrow zone around Earth supporting life
- It contains the atmosphere (all air), hydrosphere (all water), and lithosphere (all land)
- Biotic components are living things (plants, animals, bacteria)
- Abiotic components are non-living things (rocks, water, sunlight)
The Atmosphere
- The atmosphere is comprised of four layers: troposphere, stratosphere, mesosphere, and thermosphere
- The troposphere is closest to Earth's surface and contains most of the atmosphere's gases
- The stratosphere contains the ozone layer, which protects from UV radiation
- The mesosphere is a layer of decreasing temperature, where meteors burn up
- The exosphere is the outermost layer, where the atmosphere merges with space
- Temperature changes with altitude in complex patterns in certain atmospheric layers (inversion)
Electromagnetic Spectrum
- The Sun is the source of all energy on Earth
- Solar energy radiates in waves of various wavelengths, creating different types of radiation (electromagnetic spectrum)
- Different types of radiation (e.g., gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves, radio waves)
- Energy from the Sun is not all reflected/re absorbed by the Earth's surface
Earth's Axis Tilt
- Earth's axis is tilted at 23.5° relative to its orbital plane
- This tilt is the reason for seasons
- Earth's axial tilt, its orbit around the sun, and its revolution cause different amounts of sunlight to reach Earth's surfaces throughout the year
Latitudes
- Earth is divided into different latitudes
- The angle of incidence is the angle between the sun's ray and Earth's surface, affecting the amount of energy received.
- The lower the angle of incidence, the more spread out the energy, and the less energy received per unit area (and therefore, the colder the area)
Albedo
- Albedo is the percentage of solar radiation reflected by a material
- Different materials/surfaces have different albedos, influencing how much sunlight is absorbed or reflected
- High albedo materials reflect more light and tend to be cooler; low albedo materials absorb more light and tend to be warmer
- Clouds, snow, water have different albedos
Greenhouse Effect
- The greenhouse effect is a natural process where gases in the atmosphere trap heat, keeping Earth's temperature suitable for life
- This effect is caused by natural sources and intensified by human activity
- The most relevant greenhouse gases are carbon dioxide, Methane, water vapor, and nitrous oxide
Net Radiation Budget
- The net radiation budget is the balance between incoming and outgoing radiation
- Incoming radiation is solar energy reaching Earth
- Outgoing radiation is the thermal energy Earth emits back into space
- Heat is continuously transferred from hot to cold regions on Earth
Thermal Energy Transfer
- Thermal energy can transfer through radiation, conduction, and convection
- Radiation occurs in gases; conduction occurs in solids; convection occurs in fluids
Effects of Thermal Energy Transfer in the Atmosphere
- Differences in air pressure & temperature cause convection currents
- The Earth's rotation affects wind patterns (Coriolis effect)
- Wind patterns are influenced by pressure gradients and the Coriolis effect
Thermal Energy Transfer in the Biosphere
- The amount of heat required to raise the temperature of a substance is the specific heat capacity
- Q = mc∆T (where Q is thermal energy, m is mass, c is specific heat capacity, and ∆T is the change in temperature)
Phase Changes
- During a phase change, the temperature of a substance remains constant
- Heat absorbed during phase changes is called heat of vaporization or heat of fusion
- The phases include solid, liquid, and gas.
- Changes between phases include evaporation, condensation, melting, freezing, sublimation, and deposition
Heating Curve of Water
- A heating curve of water shows the temperature changes as heat is added
- Different parts of the curve represent different phases and the energy required to change from one phase to another
Biomes
- Biomes are geographical areas with specific climates, influencing the types of plants and animals that live there
- Biomes are influenced by factors like sunlight, precipitation, and temperature.
