North Pole: refers to the northern end of the earth's rotation axis, which is the point at 90° north latitude. The Arctic region refers to the area near the North Pole and within the Arctic Circle at 66°34′ north latitude. In winter, the sun is always below the horizon and the sea is completely frozen. In summer, when temperatures rise above freezing, the edges of the Arctic Ocean melt, allowing plants to grow and bloom, providing food for animals such as reindeer and musk oxen.

The Two White Hats of the Earth PPT, Part 4: Sentence Analysis

When it falls, the hot water will turn into ice, and it will crackle when it hits the ground, like setting off firecrackers.

"Crackling" is the sound made when water turns to ice and falls to the ground.

Without this cold air, the temperature in some places would remain high, and people would become "roast ducks."

"If... then..." is a hypothesis about an event that has not happened

The Two White Hats of the Earth PPT, Part Six: Expanding Application

Polar bears are the world's largest terrestrial carnivores, also known as white bears. The skin is black, and the hair is usually white in appearance because of its transparent hair.

Polar bears are huge in size and have a ferocious temperament. Their vision and hearing are equivalent to humans, and their sense of smell is extremely sensitive, seven times that of dogs. When running, the fastest speed can reach 60km/h, which is 1.5 times the speed of the world's 100-meter champion.

In recent years, due to rising global temperatures, the ice floes in the Arctic have begun to melt. Perhaps in the near future, polar bears will lose their home and become extinct like other animals. I hope that we humans can protect the environment and protect the home of polar bears.
