A's Writing Assignment Science - Week 22

A's writing assignment for science this week:

Arctic and Antarctic

The arctic is the North Pole and the Antarctic is the South Pole. Since the north and south poles are opposite each other, when one is in summer, the other is in winter. In the summer, the sun never sets, and in the winter, the sun never rises.

In the South Pole, the whole continent is filled with 8,000 feet deep ice sheet. In the winter, the average temperature is -76oF. Even in those cold climates, more than 80 species of plants survive there. Most of these plants are mosses.

In the South Pole, there are 7 different breeds of penguins. Penguins eat fish, and are mostly eaten by seals. In the artic, the biggest and strongest animal is the polar bear. They can grow up to 10 feet tall and can weigh about 2,000 pounds. Females are much smaller than males. There are more than 20,000 polar bears in the arctic.
