because they have own safety to cover our body
Explanation:
penguins can easily live in Polar regions because they have a thick layer of fat which keeps them warm as well as they have feathers which trap air inside to keep them warm.
During the day, the sun heats up both the ocean surface and the land. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse.
As you blow into the mouth of the bottle the air is moving fastest - so is at the lowest pressure. Inside the bottle, the air is moving more slowly - so a higher pressure. As the pressure is higher inside the bottle than in the mouth this pushes the paper out
