Globe and latitude and longitude PPT, part 2 content: new lesson learning

globe:

People made a model of the earth based on the shape of the earth and reduced it to a certain proportion.

(1) Earth’s axis: The axis on which the Earth rotates.

(2) Two poles:

North Pole: Point to a point near Polaris

Antarctica: The point opposite to the North Pole

(3) Longitude and latitude

Two opposing warp lines can form a large circle called a warp loop. Any meridian loop can split the Earth into two equal hemispheres. Internationally, the longitude circle composed of 200 longitude west and 1600 longitude east divides the eastern and western hemispheres.

Why don't people use the prime meridian as the dividing line between the eastern and western hemispheres?

Globe and Latitude and Latitude PPT, Part 3: Discussion Summary

Summarize the definition of meridian and its characteristics.

Definition

A semicircle (also called a meridian) that connects the north and south poles and intersects the latitude lines perpendicularly

shape

Semicircle, two opposing longitudes form a meridian loop, and each meridian loop can bisect the earth

length

All longitudes are equal in length

interrelationship

All meridians intersect at the North and South Points

interval

The distance between any two longitudes is greatest at the equator and decreases toward the poles

Indicate the direction

Indicate north-south direction
