GGR107H1 Lecture Notes - Soil Structure, Photosynthesis, Water Cycle
Document Summary
Latitude and reflection impacts the production of food -> if you"re farther north or south from the equator, there will be limited solar energy. Temperature increase of temperature = greater growth; can still have solar radiation but the temperature needs to be fairly warm - too hot = decrease levels in growth. Importance of seasonality becomes more extreme the further you go - in the greenhouse, the growing season is short and you won"t produce much. Hydrological cycle simple cycle connection between levels of precipitation and levels of evaporation (most water unavailable to use) Balance between precipitation and evapotranspiration increase in temperature = increase in evaporation. The formation of one inch of soil takes approximately 500 years (much variation) Underlying rock is broken down through physical (force > compression, movement of rock structures in earth"s surface), chemical (associated with water), or biological (plant growth, micro-organisms, worms) weathering. Factors: climate, organisms, topographical relief, parent material, time (ex. mountains, plateaus)
