Unit 4: Sources and Flow of Energy TEST CORRECTIONS

The (a)   is the thinnest part of the geosphere and makes up about 1% of the earth's total volume.

• Mantle

• Crust

• Core

• Lithosphere

Deep water ocean currents that flow as warm waters from the Gulfstream lose thermal energy, decrease in density, and sink in the Northern Atlantic. The waters then flow southward and eventually into the Pacific where they are heated again and rise. Energy flows through this system due to —

• Conduction

• Convection

• Radiation

• Deposition

​ (a)   Every energy transfer or transformation increases the entropy of the universe. The increased entropy takes the form of an increase in the amount of heat.

​ (b)   Energy is neither created nor destroyed, only transformed or transferred.

• 2nd Law of Thermodynamics
• 1st Law of Thermodynamics
• Entropy 
• Radiation
