Geography in the first year of high school asked me to tell me the complete idea

First of all, would you calculate the local solar elevation angle at the winter solstice?

Secondly, do you understand what it takes to not block the sunlight in the back building?

This is a type of problem about the distance between the buildings, in order to keep the north building of our country from being blocked from the sun, it is necessary to consider the shadow formed by the south building. On the summer solstice, the height of the sun, the shadow of the building is short; On the winter solstice, on the contrary, the shadow of the building is long. Therefore, it is necessary to consider the shadow of the building formed by the height of the sun on the winter solstice.

The shadow of the building and the distance between the buildings have to be calculated by mathematical trigonometric functions.

4. Select C A as the morning line, draw the shadow part to represent the night, you can know that the polar night phenomenon occurs near the South Pole, that is, the sun directly hits the Northern Hemisphere, choose C

5. Select D, the two corresponding meridians add up to 180 °, the time difference is 12 hours, the time of point B is 10 o'clock, because point A is the morning line, the time is 6 o'clock, the difference between the two meridians in the figure is 30 °, the difference is two hours, so that point B is 10 o'clock in the morning, then the time corresponding to it is 22 o'clock on the 4th, and the difference is 12 hours.

There are a lot of answers that need to be answered, I'm sleepy, and I'll play tomorrow when I'm done. Take a nest first.

The first chapter of the earth's movement is difficult (if you are not in Shandong, then it is also the focus), this part of the knowledge requires a certain amount of spatial imagination, I hope that your spatial imagination ability is enough, and then it is to do questions, on the basis of understanding the basic knowledge of the textbook, by doing questions to deepen the knowledge of the textbook, expand the knowledge of the textbook.

All the content of the second chapter is both key and difficult, it is recommended to be patient when learning, understand the knowledge points one by one, do not leave questions to do, and memorize the climate types very skillfully on the basis of understanding, and will use them flexibly.

The difficulty and focus of the third chapter is on ocean currents, which requires the combination of two maps, one is the current pattern map and the other is the world current distribution map, and the name of the current needs to be combined with the name of the area through which it flows as much as possible.

The first rush shouted next to the fourth chapter and the fifth chapter doesn't seem to be too difficult.,It's okay to memorize.,Of course, the natural zone in the fifth chapter must be combined with the climate type.,Remember the climate type.,Remember the natural zone.。

That's all I can help you here, I hope you can learn it well.

The geography book makes it very clear, study geography as half a science, read more and think more.

First of all, it is necessary to clarify the body of knowledge - the physical geography part.

1 Earth Movement - Overview of the Earth, Concept of Rotation and Revolution, Meaning - Method: Read the map, substitute the text with the picture. Practice appropriately. The first year of high school shouldn't be too difficult.

2 Atmosphere - composition, thermal conditions, the simplest form of movement and its application;

Three-circle circulation (the origin and movement of the distribution of the air pressure belt and wind belt).

Common weather systems (frontal systems - air masses, frontal structures, differences between cold and warm fronts) (low-pressure cyclones, high-pressure anticyclones: horizontal and vertical movement conditions, impact on weather, specific applications) Method: Diagram method, draw by yourself and talk while drawing, explain to yourself clearly, typical exercises.

3 Hydrosphere - Distribution, Types and Significance of Movement Cycles, Human Influence Links and Evaluation of Ocean Currents: Causes i.e. Dynamics, Flow Direction, Nature - Cold and Warm, Impacts: Climate, Navigation, Fisheries, Pollution, etc.

4 lithosphere - stratification, basis, and characteristics of the internal structure of the earth.

Crustal composition, lithospheric composition, rock types and transformations.

Macro-plate movement, direction and influence - key map reading map, explain the large landform form, method: know the location of geographical things without rote memorization, look at the map to remember the micro - geological structure - fold - anticline meaning and judgment. Results of the action of internal and external forces - illustration of the method.

Fault-structure, the formation of surface morphology. Illustrate.

Establish good confidence first, it is a bit difficult to build up geography in the first year of high school! 1.Remember the basic forms of the earth's movements2The significance of the revolution of the earth3Able to distinguish common weather systems.

eg.1) Frontal system – cold front and warm front (Fig., name cold front warm front.

Concept The cold air mass actively moves towards the warm air mass The warm air mass actively moves towards the cold air mass.

Weather characteristics - before the transit Single air mass control, sunny weather Single air mass control, low temperature and sunny weather.

Weather characteristics - during transit Cloudy, rain and snow, windy, cooling Continuous precipitation Cloudy, rainy and snowy, windy, cooling Continuous precipitation.

Weather characteristics - after the transit The air pressure rises, the temperature drops, the weather is sunny The temperature rises, the air pressure drops, and the weather improves.

Precipitation distribution Precipitation generally occurs after the front Precipitation generally occurs before the front.

Atmospheric examples Northern summer heavy rain, winter and spring gales, cold waves, sandstorms Northern summer heavy rain, winter and spring gales, cold waves, sandstorms.

2) Low-pressure and high-pressure systems—cyclones and anticyclones (taking the Northern Hemisphere as an example, figure Cyclone Anticyclone.

Barometric pressure Low barometric pressure (low in the center, high in the periphery) High atmospheric pressure (high in the center, low in the periphery).

Horizontal movement Convergence of the center in the direction of the periphery (north and south direction) The center diverges in all directions (north and south direction).

Vertical movement rises and falls.

Weather Mostly cloudy and rainy Mostly sunny Dry weather.

Examples: Typhoons, drought in the Yangtze River basin, "high autumn and cool" weather in the north.

4.For the type of climate to remember more about its characteristics, it is easy to confuse a few southern comparisons, think of the Mediterranean climate with the temperate oceanic climate, the savannah climate and the tropical monsoon climate. There are also some that only the northern hemisphere has and the southern hemisphere does not!

Summarize the knowledge points in a book, memorize them, do geography-related questions, and read more atlases.

Beijing time, 120°E, 12:40. At 12 o'clock in the place, then, 40 minutes later than Beijing, the corresponding longitude difference is 10 degrees (for every 15 degrees of longitude, the time difference is 1 hour, and for every 1 ° difference in longitude, the time difference is 4 minutes). So the place is 110°E.

It is the same east longitude, and the greater the degree, the earlier the time.

The same is the west longitude, the greater the degree, the later the time.

East longitude is always earlier than west longitude.

Very simple, first of all, I want to explain that the longitude of Beijing is 120 degrees east longitude, and every 15 degrees is 1 hour apart, combined with the topic, the difference between the two places is 40 minutes, that is, 2 3 hours, the longitude difference is 10 degrees, combined with the principle of east plus west subtraction, so the longitude of the desired location is 120 degrees east longitude - 10 degrees east longitude = east longitude 110 degrees hope to adopt
