Slide 3. Activation of knowledge

Interview with students. What is the shape of the earth? The most accurate, three-dimensional model of the earth is a globe. The teacher examines the globe with the children, remembers the real size of our planet, compares it with the size of other planets in the solar system.

Where else have we met with the image of our land?

slide 4. We recall the definition of a geographical map - this is a reduced image of the earth's surface on a plane, built in any projection and scale. The map is a means of scientific knowledge in geography and other earth sciences. There are maps by scale - small, medium and large. The most significant details are selected for the image on the maps, if they do not fit the scale, they are marked with off-scale signs. When building maps, the sphericity of the earth is taken into account, but distortions are inevitable on them.

Slide 5. According to the method of depicting the earth's surface and the subject matter, maps are different: general geographical, thematic, complex, contour, and others. We will get to know them in more detail next year.

slide 6. Learning new material.

To navigate on a geographical map and on a globe, to find the exact location of objects on the earth's surface allows a degree grid. The degree grid is the lines of parallels and meridians on the globe and map, they allow you to determine the address of any point on the earth's surface. The definition is written in a notebook.

Let's remember which lines you already know. The pole is the point at which the earth's axis intersects with the earth's surface. There are two poles on Earth - north and south. The equator is the line of intersection of the globe with a plane passing through the center of the Earth perpendicular to the axis of its rotation. This word comes from the Latin word "equus", which means "equal". The equator divides the globe into northern and southern hemispheres. Its length is 40,076 km. The prime meridian passes through Greenwich, a suburb of London, where the observatory is located. The north, south pole, the line of the equator and the zero meridian are located and shown by students on the map. Let's get acquainted with other lines, there are so many of them on the map.

Slide 7. A meridian is a line conventionally drawn on the earth's surface from one pole to another along the shortest path. All meridians are equal in length and their length is 40,000 km. And 1 degree of the meridian averages 111 km. The definition is written in a notebook.

slide 8. Parallels are lines that are conventionally drawn on the earth's surface parallel to the equator. The longest parallel is the equator; the length of the parallels from the equator to the poles decreases. The definition is written in a notebook.

slide 9. Geographic latitude is the angle between the plumb line at a given point and the plane of the equator. The definition is written in a notebook. It varies from 0 degrees at the equator to 90 degrees at the pole. Distinguish between northern and southern latitudes, abbreviated NL. and y.sh. Any point south of the equator will have a south latitude, north of the equator will have a north latitude. To determine the geographical latitude of any point means to determine the latitude of the parallel on which it is located. On maps, the latitude of parallels is signed on the right and left frames.

Work with the textbook. Students are jointly invited to determine the geographical latitude of objects: the cities of Moscow, London, Vladivostok, Cape Agulhas, the village of Mirny.

slide 10. Check the answers against the table.

Slide 11. Longitude is the angle between the plane of the meridian passing through a given point and the plane of the prime meridian. The definition is written in a notebook. The initial (zero or Greenwich) meridian passes through the Greenwich Observatory, located near London. To the east of this meridian, the longitude of all points is east, to the west - west. Longitude varies from 0 to 180 degrees. E.d. is abbreviated. and h.d. To determine the geographical longitude of any point means to determine the longitude of the meridian on which it is located. On the maps, the longitude of the meridians is signed on the upper and lower frames, and on the map of the hemispheres - on the equator.

Work with the textbook. Students are invited to determine the geographical longitude of cities: Moscow, St. Petersburg, Washington, Santiago, Canberra.

slide 12. Check the answers in the table

slide 13. Latitude and longitude of any point on the earth's surface leave its geographical coordinates. The term "longitude" and "latitude" have come down to us from ancient sailors, who gave a description of the length and width of the Mediterranean Sea. The one that corresponded to the length of the Mediterranean Sea became longitude, and the one that corresponded to the width became the modern latitude.

Practical work. Students are jointly invited to determine the geographical coordinates of the volcanoes: Kilimanjaro and Krakatoa, Mount McKinley. Find objects by geographical coordinates: the city of Paris, islands: Easter, Sri Lanka.

Cards are distributed in 2 versions, on which the task is given to determine the geographical coordinates of 5 objects (cities, mountain peaks, volcanoes, islands) and find 2 objects at the given coordinates.

slide 14. The guys check the answers according to the table on the slide.

On the final stage students reflect.

slide 15. Homework. Determine the geographical coordinates of three cities of your choice.
