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.
