Test core:
Globe: people imitate the shape of the earth and reduce it in a certain proportion to make a model of the earth - the globe.
(1) The earth axis - the imaginary axis of the earth's rotation (2) The poles - the earth axis passes through the earth's center and intersects the earth's surface at two points. The point pointing to the North Star is called the North Pole; The opposite of the North Pole is called the South Pole.
(3) Equator - a large circle on a globe that is equidistant from the north and south poles.
Longitude and latitude lines: Longitude and latitude lines are drawn on the globe and map in order to determine the position and direction on the earth. There is no longitude and latitude line on the ground. The line connecting the north and south poles is called longitude. The line perpendicular to the longitude is called the weft line. A weft line is a circle of unequal lengths. The longest latitude line is the equator. Because longitude indicates the north-south direction, it is also called meridian. According to international regulations, the longitude passing through the original site of the British Greenwich Observatory is called the 0 ° longitude, also called the prime meridian. On the earth, the longitude indicates the north-south direction, and the latitude indicates the east-west direction.
(1) Latitudinal line: a circle circling the earth in the east-west direction.
(2) A line connecting the north and south poles and perpendicular to the latitude line.
