Read the Australian topography and climate map and the "Africa Climate Distribution Map" to complete the following questions (1) The ______ line passes through central Australia; the ______ line passes through

(1) It can be seen from the picture that the Tropic of Capricorn passes through central Australia. Africa is located in the western part of the Eastern Hemisphere, stretching north and south of the equator. Most of the two places are located in the tropics;

(2) The Australian continent has a low and flat terrain, and the continent can be clearly divided into three major terrain regions from west to east. The west is a broad and flat plateau, generally 200 to 500 meters above sea level, accounting for about 60% of the continental area. The central plain area accounts for approximately 25% of the total continental area and is one of the largest endorheic basins in the world. When wells are dug in low-lying areas in the middle of the plain, groundwater can automatically flow out of the ground and become artesian wells, so it is also called the "Great Artesian Basin". Artesian well water has high salinity and is not suitable for irrigating farmland, but it can be used as drinking water for livestock. The Eastern Mountains start from the Cape York Peninsula in the northeast to the east coast of southwestern Victoria in the south. It is an arc-shaped area composed of a series of narrow mountains and valleys, also known as the Great Dividing Range. In 2000, Australia's total population was 19.18 million, most of whom lived in the southeastern coastal zone with a warm and humid climate;

(3) The annual precipitation in the savanna climate zone is far less than that in the tropical rainforest climate zone, and the precipitation is The distribution is very uneven throughout the year, with more rain in half the year and less rain in the other half. In the rainy season, the prairie is green and full of vitality. In the dry season, the weather is hot and dry, and everything is dry and yellow. There are no lush forests here. On the vast grassland, there are occasionally some drought-tolerant solitary trees. Many animals migrate in order to survive and chase water sources. The savanna climate zones in Africa and South America are the main habitats for herbivores such as zebras, giraffes, and wildebeests. Lions, cheetahs, hyenas, etc. that feed on these animals also appear here from time to time.

So the answer is: (1) South Tropical; Equator; Hot; (2) Plateau; Large Artesian Basin; Groundwater; Southeast Coast; Mild and Humid; (3) North and South; (4) B.
