Earth, system of meridians and parallels on geographical maps and globes, used to measure the geographic coordinates of points earth's surface- longitude and latitude. All points of a given meridian have the same longitude, and all points of the parallel have the same latitude. In geodesy, the figure of the Earth is taken to be an oblate ellipsoid of revolution, on which the meridians are ellipses passing through the earth's poles, and the parallels are small circles, the planes of which are perpendicular to the axis of rotation of the Earth and parallel to the earth's equator. Due to the compression of the earth's ellipsoid, the linear distance between parallels drawn through equal number degrees, increases slightly from the equator to the poles. On the Geoid, meridians and parallels are curves of double curvature, although they are very close to ellipses and circles, respectively.

Earth degree network– a system of meridians and parallels on geographic maps and globes, used to count the geographic coordinates of points on the earth’s surface - longitudes and latitudes - or to plot objects on the map according to their coordinates.
To create a degree network, certain reference points are required. Ball shape The earth is determined by the existence on the earth's surface of two fixed points –poles. An imaginary axis around which the Earth rotates passes through the poles.
The main elements of a map's degree grid - poles, equator, meridians and parallels.
Geographic poles – mathematically calculated points of intersection of the imaginary axis of rotation of the Earth with the earth’s surface.
Equator - an imaginary line on the earth’s surface, obtained by mentally dissecting the ellipsoid into two equal parts (Northern and Southern Hemisphere).
All points of the equator are equidistant from the poles. The plane of the equator is perpendicular to the Earth's axis of rotation and passes through its center. The hemispheres are mentally separated by many more planes, parallel to the plane equator.
The lines of their intersection with the surface of the ellipsoid are called parallels .
All of them, like the equatorial plane, are perpendicular to the axis of rotation of the planet. You can draw as many parallels on a map and globe as you like, but usually educational maps they are carried out at intervals of 10-20°. The parallels are always oriented from west to east. The circumference of the parallels decreases from the equator to the poles. At the equator it is greatest, and at the poles it is zero.
When the globe is crossed by imaginary planes passing through the Earth’s axis perpendicular to the equatorial plane, great circles are formed - meridians .
Meridians can also be drawn through any points of the ellipsoid. They all intersect at the pole points. The meridians are oriented from north to south. Average length arc 1° meridian: 40,008.5 km: 360° = 111 km. The length of all meridians is the same. The direction of the local meridian at any point can be determined at noon by the shadow of any object. In the Northern Hemisphere, the end of the shadow always points north, in the Southern Hemisphere it always points south.
Degree network necessary for calculating the geographic coordinates of points on the earth’s surface - latitude and longitude.
Geographic coordinates.
Geographic coordinates are geographic latitude and longitude.
Geographic latitude– the distance along the meridian in degrees from the equator to any point on the Earth’s surface.
The origin is the equator. The latitude of all points on it is 0. At the poles the latitude is 90°. North of the equator is counted northern latitude, to the south - southern.
Geographic longitude– the distance along the parallel in degrees from the prime meridian to any point on the earth’s surface.
All meridians are equal in length, so it was necessary to choose one of them for counting. It became the Greenwich meridian, passing near London (where the Greenwich Observatory is located). Longitude is measured from 0° to 180°. To the east of the prime meridian up to 180° eastern longitude is measured, to the west - western longitude. Thus, using a degree network, it is possible to accurately determine geographic coordinates - quantities that determine the position of a point on the earth’s surface relative to the equator and the prime meridian.
Degree network Earth, a system of meridians and parallels on geographic maps and globes, which serves to measure the geographic coordinates of points on the earth’s surface - longitudes and latitudes. All points of a given meridian have the same longitude, and all points of the parallel have the same latitude. In geodesy, the figure of the Earth is taken to be an oblate ellipsoid of revolution, on which the meridians are ellipses passing through the earth's poles, and the parallels are small circles, the planes of which are perpendicular to the axis of rotation of the Earth and parallel to the earth's equator. Due to the compression of the earth's ellipsoid, the linear distance between parallels drawn through an equal number of degrees increases slightly from the equator to the poles. On the Geoid, meridians and parallels are curves of double curvature, although they are very close to ellipses and circles, respectively. A. A. Mikhailov.

Objective of the lesson: form a concept about the degree grid, determine how it looks on the globe and maps, form a concept about the difference between the images of meridians and parallels on it.
Tasks:
- Developmental:
- develop the ability to work with a map;
- develop practical skills finding meridians and parallels on the globe and map, characterizing their features;
- develop interest in the subject being studied.
- Educational:
- cultivate a desire to expand your horizons;
- stimulate interest in working with maps and atlases.
Equipment: textbooks, atlases, wall map of the hemispheres, globe, presentation ( Appendix 1 ), handouts.
Basic concepts: map, globe, equator, hemispheres, axis, degree grid, meridians, parallels.
Lesson type: combined.
PROGRESS OF THE LESSON
– Good morning, Guys! Today I’m in a great mood, I’m glad to meet you.
How are you guys in the mood? ( Appendix 2
. Distribute in advance). Show the symbol that matches your mood.
One poet said: “Consider that you have lost a day in which you did not smile.”
And so that he is not lost, look at each other and smile, mentally wish him success.
(This technique allows the teacher to assess the emotional state of students at the beginning of the lesson).
1. Geographical warm-up - repetition
Teacher: What are the terms of the topic: Site plan - scale - do we know?
Working with terms:
II. Call stage
– Name and show these hemispheres on globes. Today the equator passes here (the teacher “lays” the equator around the class: he puts the tape in the hands of two students so that it passes between the groups and two of them end up on one side of the line, and two on the other.)
– Open the textbook on page 28. Write in your notebook: Helper lines – longitudinal and transverse lines (parallels and meridians) make up the degree grid, with which you can determine the position of any object on our planet. ( Appendix 6
)
Decreasing to the north and south,
They managed to preserve the circle shape.
They are all parallel to each other,
That's why they are called parallels.
The biggest one is called the equator,
The small one is the pole point.
Everyone from the east is moving to the west,
And they are used to search for latitudes.
Write in your notebook: Parallel – These are conditional lines drawn parallel to the equator.
The whole globe is crossed,
Converge at the poles.
Gradually moving
Hands on any clock.
Across land, oceans
The meridians ran.
Write in your notebook: Meridian – a conventional line drawn through the poles.
– What are the helper lines called? (Meridians and parallels).With the help of meridian lines and parallels on the map, you can determine the direction and indicate the position of parts of territories and objects.
Make a syncwine:
- 1 option with the word meridians,
- Option 2 with the word parallels.
– The Prime Meridian is... (Greenwich meridian)
- Today it passes here (the teacher “lays” the Greenwich meridian around the class in a similar way to the equator.) The zero meridian is the Greenwich meridian. Its longitude is 0°.
From the Greenwich meridian we begin counting in degrees, following strictly along the parallel to the west or east. To the west of the prime meridian, all points have western longitude (W), to the east - eastern longitude (E). Western and eastern longitudes are measured from 0° to 180°. Russia is located in both hemispheres - Eastern and Western, since the territory of our country is crossed by the 180th meridian.
