CHAPTER 6: BIOMES 1 SECTION 6.1 WHAT IS A BIOME? A BIOME IS A LARGE REGION CHARACTERIZED BY TWO FACTORS: CLIMATE AND PLANT LIFE. CLIMATE IS THE WEATHER CONDITIONS (TEMPERATURE AND PRECIPITATION) IN AN AREA OVER A LONG PERIOD OF TIME.

2 PLANT LIFE THE TWO MAIN FACTORS THAT DETERMINES WHAT TYPE OF PLANTS GROW IN A BIOME ARE TEMPERATURE AND

PRECIPITATION. 3 LATITUDE VS. ALTITUDE LATITUDE ALTITUDE THE DISTANCE THE HEIGHT OF AN
