Explanation:

The above mentioned are the characteristics of Savanna.The above mentioned statements are correct regarding Savannah.
Savanna, also spelled savannah, vegetation type that grows under hot, seasonally dry climatic conditions and is characterized by an open tree canopy (i.e., scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground). The largest areas of savanna are found in Africa, South America, Australia, India, the Myanmar (Burma)–Thailand region in Asia, and Madagascar.
Climates across the world became steadily cooler during that period. Lower ocean surface temperatures reduced water evaporation, which slowed the whole hydrologic cycle, with less cloud formation and precipitation. The vegetation of mid-latitude regions, lying between the wet equatorial areas and the moist cool temperate zones, was affected substantially.
