Columbian Exchange and Ecological Change · US History

The practice of 'slash-and-burn' agriculture in the Americas was often replaced by European farmers with:

  1. The use of iron plows and domesticated draft animals
  2. Total reliance on gathering wild berries
  3. Hydroponic farming in coastal areas
  4. The construction of large stone terraces in the plains
Show answer and explanation

Correct answer: The use of iron plows and domesticated draft animals

European farming techniques involved deep tilling with metal plows and the use of animals like oxen. This shifted the landscape from a patchwork of forest and clearings to large, permanent open fields.
