Read the topographic and climatic map of Australia and the climate distribution map of Africa to complete the following questions (1) _ _ line passes through central Australia; _ _ _ _ _ line passes through (1) As can be seen from the picture, the Tropic of Capricorn runs through central Australia. Africa is located in the western part of the old hemisphere, across the equator. Most of them are located in the tropics.

(2) The Australian mainland is low-lying, which can be clearly divided into three topographic regions from west to east. The west is a vast and flat plateau with an altitude of 200-500 meters, accounting for about 60% of the mainland area. The central plain accounts for about 25% of the total area of the mainland and is one of the largest internal flow basins in the world. When a well is dug in the low-lying area of the central plain, groundwater can automatically flow out of the ground and become a artesian well. Therefore, it is also called "great artesian basin". Artesian well water is not suitable for farmland irrigation because of its high salt content, but it can be used as drinking water for livestock. The eastern mountainous area starts from Cape York Peninsula in the northeast in the north and reaches the east coast of southwest Victoria in the south. It is an arc zone composed of a series of long and narrow mountains and valleys, also known as the Great Watershed. In 2000, the total population of Australia was 65,438+0,965,438+0.8 million, and most of them lived in climate.

(3) The annual precipitation in the tropical grassland climate zone is much less than that in the tropical rain forest climate zone, and the annual distribution of precipitation is very uneven, with more rain for half a year and less rain for half a year. In the rainy season, the prairie is lush and full of vitality. In the dry season, the weather is hot and yellow everywhere. There are no lush forests here, but there are some drought-tolerant solitary trees on the vast grassland. Many animals migrate in order to survive and chase water.

So the answer is: (1) retreat south; Equator; Heat; (2) Plateau; Great artesian basin; Groundwater; Southeast coast; Mild and moist; (3) North and South; (4)B。
