• The second agricultural revolution saw advancements in machinery and tools.
• The third agricultural revolution (Green Revolution) introduced GMOs and GEOs.

Economic Sectors

• Tertiary sector focuses on providing services (e.g., healthcare, education, law, retail).

Break-of-Bulk Points

Weber's Least Cost Theory

• Weight-gain industries (e.g., soda bottling, machinery) locate closer to markets due to the increased weight of the finished product compared to raw materials.
• Weight-loss industries (e.g., copper, steel production) locate closer to raw material sources because the finished product weighs less than the raw materials.
