Globe and latitude and longitude network PPT, part 2 content: longitude and longitude

Self-learning

Observe the globe, read and think about the picture, and complete the following questions.

1.What is a meridian?

On a globe, the semicircular arc connecting the north and south poles

2. What are the characteristics of the shape, length and indicated direction of the meridian?

Shape: semicircle

Length: all equal

Direction: Indicates north-south direction

1. What is longitude?

In order to distinguish each meridian, people marked the meridian with degrees. This is longitude.

2. Which meridian does longitude start from?

prime meridian

3. Starting from the prime meridian, in what directions are the longitudes arranged?

Arranged in east-west direction

What is the range? What are the rules?

0°～180° Starting from the prime meridian, it gradually increases eastward and westward.

Globe and latitude and longitude network PPT, the third part: lines of latitude and latitude

collaborative inquiry

1.What is latitude?

2. Is the latitude line a circle or a semicircle?

What direction do parallel lines indicate?

Are the lengths of the parallels equal?

3. Which is the longest parallel?

What is the pattern of changes in the length of latitude lines?

gradually shortens from the equator to the poles

4. How many lines of latitude are there on the globe?

Countless

Globe and Latitude and Latitude PPT, Part 4: Exploration and Application

1. The maximum latitude is _____, and there are _____ lines of latitude.

2. The smaller the latitude, the latitude line _____; the larger the latitude, the latitude line _____.

3. If you walk straight ahead along a certain latitude, can you return to the starting point without changing the direction?

able. Parallels of latitude are circles that circle the earth in the east-west direction. If you keep moving forward along a certain latitude, you can return to the starting point.

4.The dividing line between the northern and southern hemispheres is _____. Does northern latitude have to be in the northern hemisphere, and southern latitude has to be in the southern hemisphere?

Tip: Yes. The equator is the dividing line between north and south latitudes, and the dividing line between the northern and southern hemispheres, so northern latitude (N) must be in the northern hemisphere, and southern latitude (S) must be in the southern hemisphere.

[Student Assistance Weibo] Interpretation of North and South Latitude and East and West Longitude

(1) If there is an equator (0° latitude) in the label, then north of the equator is north latitude (N) and south of the equator is south latitude (S).

(2) If the equator (0° latitude) does not appear in the label, the value increases north to north latitude (N) and south to south latitude (S).

(3) If there is a 0° longitude in the label, then the east longitude (E) of the 0° longitude is the east longitude (E), and the west longitude (W) is the west longitude.

(4) If the 0° longitude does not appear in the label, the value increases eastward to east longitude (E) and westward to west longitude (W).
