Answer:
1). Penguins have to keep high body temperatures to remain active. They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather. They also huddle together with their friends to keep warm. ... Penguins tightly packed feathers overlap to provide waterproofing and warmth.
2). The sea has a greater heat capacity than land, so the surface of the sea warms up more slowly than the land's. ... The air above the sea has a relatively higher pressure, causing air near the coast to flow towards the lower pressure over land.
