1, water, gold, fire, wood, earth, Neptune, Pluto around the outside; Only the earth is alive, and the warm air, liquid and water are caused by fate. nine planets

2. The equator is slightly bulging and the poles are slightly flat. From west to east, time began to change. North and South are parallel lines, which are relatively equal circles. Things are longitude lines, which form parallel circles separately; The equator is the longest, and polarization is the focus. -Characteristics of the Earth

3, 20 degrees west longitude, east longitude 160 degrees, the whole line runs through the eastern and western hemispheres. The northern and southern hemispheres are divided, the equator is zero latitude, the temperate zones of the four seasons are obvious, and the north and south are opposite. -East, West, North and South Hemisphere Division

4. Identify the direction of the map and put it in front of you; From north to south, from left to west and from right to east. The plot is easy to distinguish, but the latitude and longitude network is difficult; Weft refers to the north-south and east-west warp circles. In the polar projection, the orientation is special: for the northern hemisphere, the four Nan Zhou in the north, the east and west of the northern latitude circle, rotate counterclockwise. For the southern hemisphere, north and south around the heart; South latitude circle east and west, rotate clockwise. -Use a map to determine the direction

5, the surface covers an area, Asia, Europe, Africa, South. Asia and Europe are integrated, and Ulagao adds points to both sides. Asia and Africa were originally connected, and the Suai Canal was dug; Asia and North America are separated by water, with the Bering Strait in the middle; China, the United States, the North and the South all came to help, and the Bana Canal was blocked. -The boundaries and locations of the seven continents
