Study Notes

Climate Regulation

  • Global warming refers to the increase in the earth's average air temperature, which may cause changes in crop production regions and increases in extreme weather.
  • Greenhouse gases are associated with global warming, and reducing carbon dioxide is a potential solution.

Climate

  • Climate is the typical long-term weather in a region, influenced by several factors: solar energy, bodies of water, land forms, elevation, and air masses.
  • Precipitation and temperature are important features of climate that affect agriculture.

Climate Classification

  • The Greek system is a very limited and general basis for today's climate classification systems.
  • The Koppen system divides the earth into climatic regions based on temperature and precipitation, with five major climate types: tropical, dry, moist mid-latitude with mild winters, moist mid-latitude with cold winters, and polar climates.

The Sun's Energy

  • The sun is the driving force behind climate, and the quality, duration, and intensity of its energy influence plants.
  • The solar energy received is influenced by latitude, season, and time of day.
  • Seasonal and day-length effects are caused by the interaction of the earth's inclination, yearly orbit, and daily spin.

Light Effect on Plants

  • Light affects plants in three ways: light quality (420-460 & 620-680 nm), light duration, and light intensity.

Our Atmosphere

  • The atmosphere is a gaseous layer extending up to 70 miles, composed of the troposphere, stratosphere, mesosphere, and thermosphere.
  • The atmosphere has four functions: source of water vapor, protection from radiation, selective passage of radiation, and temperature regulation.
