Study Notes
Climate Study Guide
- Atmospheric Dust: Composed of soot, pollen, and microorganisms.
- Biosphere: The thin layer of Earth that supports life, encompassing all living things and their environment. Divided into three components.
-
Atmosphere: Composed of a mixture of gases.
- Nitrogen (78.08%): Crucial for plant growth.
- Oxygen (20.95%): Necessary for cellular respiration in living organisms.
- Other gases (0.97%): Examples include water vapor and carbon dioxide.
- Rises over 500km from Earth's surface.
-
Atmospheric Layers: Divided into four layers: troposphere, stratosphere, mesosphere, thermosphere.
- Troposphere: Average temperature 15°C, 80% of atmospheric gases are here, nearly all life is in this layer.
- Stratosphere: Temperature increases with altitude, contains most of the ozone layer.
- Mesosphere: Temperature decreases with altitude; clumps of cells exist.
- Thermosphere: Temperature increases with altitude, auroras occur here.
- Lithosphere: Includes the crust and upper mantle (rigid outer layer of Earth). Contains a 100km depth of plants, animals, and microorganisms. Warmed by solar and geothermal energy (from the core).
- Hydrosphere: All water on Earth (liquid, solid, and vapor). 97% is saltwater, 3% is freshwater (e.g., ice, glaciers, polar caps). Warmed by solar radiation.
- Water Exists in 3 Parts of Biosphere: Water vapor in the atmosphere, water in soil, groundwater/water in the lithosphere.
Conditions Affecting Tree Rings
- Warm and Wet Conditions: Wider and denser rings indicating more water and faster growth.
- Cold and Dry Conditions: Narrower rings, thinner and less defined wood, indicating scarce water availability.
- Insulators: Materials that resist heat flow, trap heat, or slow its transfer (e.g., snow, air gaps, wood).
- Conductors: Materials that allow heat to pass through them easily (e.g., metals).
Insolation and Earth's Surface
- Insolation: The amount of solar radiation that strikes a particular region of Earth's surface.
- Equator Receives Most Insolation: Direct solar radiation results in maximum insolation.
- Albedo: The percentage of solar radiation reflected by a surface. Darker surfaces have lower albedo (absorb more); light surfaces have higher albedo (reflect more).
- Angle of Incidence: The angle at which the sun's rays strike the Earth's surface. The angle affects the intensity of solar radiation.
Greenhouse Effect
- Greenhouse gases in the atmosphere trap heat from the sun, warming the Earth's surface.
- Prevents infrared radiation from escaping, keeping Earth warmer.
- Water vapor is a major contributor.
Wind and Ocean Currents
- Wind Currents: Redistribute heat and moisture globally, influencing weather patterns.
- Ocean Currents: Move heat across the globe, influencing coastal climates and marine ecosystems.
- Both (wind and ocean currents) are critical for regulating Earth's climate and supporting weather extremes.
-
Angle of Inclination: Earth's tilt (23.5 degrees) affects the distribution of solar radiation and seasons.
- Coriolis Effect: The deflection of objects from a straight path due to Earth's rotation.
-
Convection Currents: Are driven by the unequal heating of a fluid, creating a continuous cycle of rising warm fluid and sinking cool fluid. Occurs in atmosphere, oceans, and Earth's interior.
- Examples of Scientist Activities: ice samples, tree rings, fossil records.
- Net Radiation: Incoming and outgoing radiation, balance of energy.
Heat Transfer and Energy
- Q = mcΔT: Formula for calculating heat transfer.
- Specific Heat: The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
- Heat of Fusion/Vaporization: Energy required to change substance state (solid to liquid, liquid to gas).
- Open System (Biomes): Exchange both energy and matter with the surroundings.
