iii) Temperature, humidity and precipitation also affect the type of vegetation and wildlife. In hot wet regions of Assam and Kerala, elephants and tropical evergreen trees are found. In high mountains, coniferous forests can be seen. In Alpine, tundra region mosses and lichen grow and snow-leopards are found.
iv) Varyingamount of rainfall from 20 cm to 300 cm. Duration of rainfall period also varies and gives variety of vegetation.
v) The variation in duration of sunlight at different places due to difference in latitude and altitude, season and duration of the day also affect vegetation. Due to longer duration of sunlight, trees grow faster.
