Explanation:
Carbon dioxide and other greenhouse gases in the atmosphere prevents long wave radiation from leaving the earth and in the process, it raises global temperatures.
- Greenhouse gases helps to maintain the fair balance in temperature on the earth surface.
- They keep the temperature of the earth in balance by preventing it from losing all of the heat it gains.
- Radiation from the sun reaches the surface as short wave radiations.
- When they get absorbed and re-emitted, they produce long wave thermal radiations.
- In the atmosphere, the radiations are cut off and causes warming due to their interaction with greenhouse gasses there
- When the amount of these gases in the atmosphere become more than normal, more heat becomes trapped.
- This leads to an anomalously high surface temperature on earth.

Unlike the hippo's ancestor, whale ancestors moved to the sea and evolved into swimming creatures over a period of about 8 million years. Fossils of gigantic ancient whales called Basilosaurus were first mistaken for dinasaur fossils but were later recognised as mammals.
An example could be oil (olive, almond)
