  2. Savanna – Characterized by a mix of grasslands and sparse trees, with distinct wet and dry seasons.
  3. Desert – Defined by very low precipitation and can be hot or cold.
  4. Temperate Grassland – Features large open spaces of grasses and few trees, with moderate rainfall.
  5. Temperate Deciduous Forest – Consists of trees that lose their leaves in the fall, with moderate temperatures and rainfall.
  6. Taiga (Boreal Forest) – Characterized by coniferous forests and cold climates.
  7. Tundra – Known for its cold, treeless landscapes with permafrost.

These biomes vary in terms of temperature, precipitation, and vegetation, reflecting the diverse environments found on land.
