Exam Questions

11)   What are the 3 types of rocks and how do each morph into the other classes (drawing a diagram works as well)?

Igneous – They become sedimentary through weathering and erosion into sediment before burial and lithification in the oceans. They become metamorphic rocks through heat and pressure.

Sedimentary – They become metamorphic through heat and pressure. They can become igneous after shifting into metamorphic rocks by melting into magma before cooling upon reaching the surface.

Metamorphic – They become sedimentary through uplift, then weathering and erosion before burial and lithification in the oceans. They become igneous by melting into magma and cooling upon contact with the Earth’s surface

22)   What is the chemical equation for photosynthesis?

6CO₂ + 6H₂O + Light Energy -> C₆H₁₂O₆ + 6O₂

33)   What is gross primary product (GPP) and how can it be calculated via satellite indexes?

Gross primary product is the rate at which ecosystems capture and store energy in biomass in a given period of time.  One formula for calculating GPP is:

GPP = LUE (light use efficiency) x PAR (photosynthetically active radiation x NDVI (normalized difference vegetation index)
