What are the key contents of geography in the second year of high school, and what are the knowledge

1. Progressive change in longitude:The degrees to the east increase to the degrees of east longitude, and the degrees to the west to the degrees of west longitude.

2. Progressive change of latitude:The number of degrees to the north increases to the north latitude, and the degree to the south increases to the south latitude.

3. The shape and length of the weft:Circles parallel to each other, the equator is the longest coil of latitude, which gradually shortens towards the poles.

4. The shape and length of the warp:All meridians are semicircles that meet the north and south poles and are all of equal length.

5. The judgment of the East and West Classics:The east longitude increases along the direction of rotation and decreases the west longitude.

6. Judgment of north and south latitudes:The degree increases to the north to the north latitude and to the south to the south latitude.

7. The division of the eastern and western hemispheres:20°W east to 160°E for the Eastern Hemisphere, 20°W west to 160°E for the Western Hemisphere.

8. Judgment in the east-west directionThe law of inferior arcs (e.g. 80° east longitude at 1° east longitude and 170° west longitude west longitude).

Summary of geography knowledge points in the second year of high school:1. Geographical location analysis:

Absolute Position Relative position.

1) Hemispheric position.

2) The location of continental borders or national borders.

3) Longitude and latitude location: high, low, mid-latitude, tropical, temperate, and cold zones.

4) Land and sea location.

5) Relative location: adjacent areas (national, economically developed areas); Transportation location (important straits, railway junctions, ports).

2. Describe the topographical characteristics of a place:

1) What terrain is the main one (five major terrains).

2) Undulating terrain (relative height, large and small).

3) Topography characteristics (east, west, north, south, middle, which is high and which is low).

3. Topographic distribution characteristics of a certain place:

Describe which direction is dominated by what terrain.

4. The basis for judging the topography:

1) Distribution of contour lines.

2) The direction of the river flow (as opposed to the contour convex direction).

3) The shape of the water system (centripetal is the basin, low in the middle and high on the periphery, radial is the mountain, high in the middle and low on the periphery).

5. Geomorphological (topographical) characteristics of some topographic areas in China:

1) Qinghai-Tibet Plateau: Snow-capped mountains and glaciers are widely distributed.

2) Yunnan-Guizhou Plateau: rugged and uneven, the land is not three miles flat.

3) Inner Mongolia Plateau: The ground is open.

4) Loess Plateau: fragmented, thousands of ravines.

5) Hengduan Mountainous Area: The mountains are high and the valleys are deep, and the mountains and rivers are intertwined.

The geography knowledge points of the second year of high school are summarized as follows:1. The density of the contour line: the denser the medium high line in the same picture, the steeper the slope; The denser the isobar, the stronger the wind; The denser the isotherms, the greater the temperature difference.

2. Convex direction and topography of the contour line: the place where the contour line protrudes to the high place is the valley, and the place where the contour line protrudes to the low part is the ridge.

3. The convex direction of the contour line and the river: The contour contour convex direction is opposite to the flow direction of the river.

4. The convex direction of the isotherm is the same as that of the ocean current: the convex direction of the isotherm is the same as that of the ocean current.

5. Determination of the direction on the map: in general, "up the north, down the south, left west, right east"; There is a map pointing to the target, and the arrow pointing to the target points to the north; The graticule map, the warp line indicates the north-south direction, and the insight is that the latitude line indicates the east-west direction.

1. The shape and size of the earthThe Earth is a sphere.

For the first time, a fleet led by the Portuguese navigator Magellan made it possible for a man to circumnavigate the globe.

2. Weft and warpParallel: A circle perpendicular to the Earth's axis and orbiting the Earth.

The parallels are unequal, and the equator is the largest coil of latitude.

Longitude: A semicircle that connects the north and south poles and intersects perpendicular to the parallels.

The warp threads are of equal length.

3. Latitude and longitude.

The law of latitude changes: from the equator (0° parallel) to the north and south poles. The maximum latitude is 90 degrees, at the South Pole, the North Pole.

The latitude north of the equator is called north latitude and is denoted by "n"; The latitude south of the equator is called southern latitude and is denoted by an "s".

4. The movement of the earth.

A natural phenomenon that occurs when the earth moves in what direction it turns.

The seasons in the Northern Hemisphere are reversed from those in the Southern Hemisphere (spring-autumn; Summer-winter).

5. Maps.

The three elements of a map: scale, direction, and legend.

Scale type: line segment scale, digital scale.
