• A rolling grassland scattered with shrubs and isolated trees • Can be found between a tropical rain forest and a desert • They are also • A savannah is also known found in a wide as tropical grasslands band on either side of the equator between 15-25 degrees N. and S. on the edges of a tropical
Climate Average Annual Temperature: season 93degrees
During dry
During wet season 61degrees Not enough rain falls on a savannah to support forests
Average Annual Precipitation = 59in. ď‚— More rainfall occurs during the summer vs. the winter
Seasons • Have warm temperatures year round.
There are two different seasons In this biome, ocean air masses are blocked by mountain ranges to the west and south. Which • Very wet allows polar air masses to • Lots of rain dominate in the winter • Hot and humid months and in the summer, continental air mass to dominate.
-Summer-
-Winter• Very long • Dry
Geology
• Savanna’s are distinguished by their warmer drier climates, and their seasonal
• Savannah are located in the dry tropics and the subtropics often bordering a rain forest. • This environment is intermediate between a grassland and a forest. • Savannahs are located in Africa, Madagascar ( an island off the east coast of Africa), Australia, South America, India, and the MyanmarThailand region of southeast Asia.
n o s a e S g n i w o r G Noun: The part of the year during which rainfall and temperature allow plants to grow. • The growing season in a savanna biome is year round (limited during seasonal drought)
• The longer the dry period the fewer the trees.
Soil • Porous, with rapid drainage of water.
• Has only a thin layer of humus (the organic portion of the soil created by partial decomposition of plant or animal matter), which provides vegetation with nutrients.
