The earth’s temperature is kept constant by the balance of heat loss and the heat gained from the sun. The atmosphere naturally constitutes greenhouse gases. The heat that is being trapped by this process increases with the increase in the concentration of greenhouse gases in the air. Global WarmingSeveral human ... Read More

Elephants live in hot, harsh environments, with intermittent droughts and surrounded by predators. Elephant’s adaptation helped them to survive harsh conditions.\r\rElephant’s adaptation features are as follows:\r1) Structural adaptation: Sweat glands are absent in elephants, thus they flap their ears to cool themselves.
