Geography calculation questions in high school year, do you also have calculation questions in high

Without further ado, this is a theoretical data calculation. Because it is a geographical calculation in the first year of high school, there are not many factors to consider. The question obviously examines that for every 1,000 meters of increase in atmospheric temperature, the temperature drops by 6 degrees Celsius.

This is related to the distribution of the Earth's atmosphere and the composition of each layer, which is divided into three layers: troposphere, stratosphere, and upper atmosphere. The thickness of the troposphere varies from place to place on Earth, from about 15 km near the equator, to about 12 km at mid-latitudes (30-60) and 8 to 10 km at high latitudes.

In the troposphere, the temperature decreases with altitude, but in the stratosphere it increases with altitude (the stratosphere is mainly composed of ozone, which absorbs a lot of ultraviolet rays and is very hot), while the upper atmosphere is dominated by electric ions, the air is thin and the temperature is very low. So this question should be taken into account, and the answer is that the temperature is about 50-52 degrees.

The thickness of the troposphere varies throughout the planet, about 15 kilometers near the equator.

The air was thin, indeed 50 to 52 degrees as the two upstairs said.

The answer is obviously a rigid formula! It's unrealistic, and I persuade the landlord not to look at it. Everything starts with reality!

Actions speak louder than words.

There is only one truth.

The landlord can't help it

It is China's limited education system

Deeply sympathetic

For every 100 meters of elevation, the temperature drops by 6 degrees.

Within a certain altitude, for every 1,000 meters of altitude increase, the temperature drops by 6 degrees Celsius. Therefore, the temperature at 15000 meters is 30-6 * (15000 1000) = -60 degrees Celsius.

Upstairs, your calculation formula is correct.

The air temperature decreases as the altitude rises.

But you ignored it.

At an altitude of about 12 km, the temperature rises, and at an altitude of 50 km, the temperature decreases again.

It's an S-shaped distribution map.

I went to check the information at an altitude of 12 kilometers, the temperature was around minus 60 °C, at a distance of 15 kilometers, the temperature was about 50-52 degrees, thank you Alas, there is no help, the answers are all wrong.

I guess you won't believe me, go check the professional information yourself.

It would be a mistake to use the dead formula here.

Your answer, alas, is also wrong.

In the first year of high school, geography is so simple? Speechless.

There are calculation questions.

1. Calculation of the earth's motion.

Question types: time calculation, solar altitude angle calculation, morning and dusk line calculation, date line calculation, yellow-red intersection angle calculation, etc.

Characteristics of the questions: difficult, less test score (up to 4 points), less connection with other knowledge. (If you can't give up directly in the third year of high school).

2. Calculation of contours.

The values of each point on the same contour line are equal.

Two adjacent contours can be equal or one difference d.

Contours generally do not coincide, and all contours are closed, but they are not necessarily closed in the same image due to frame limitations.

When a contour is closed, it is likely to be a high or low point. (greater than the big one, smaller than the small one).

Contour convex or concave indicates higher or lower than the surrounding value, and the greater the concave or convex curvature, the greater the change. (Convex height is low, convex low is high, high and low refers to the level of the value).

Yes, the main thing is to calculate the time.

(1) 20°S, (70°N-90°N is the polar night, which means that the sun shines directly for 20°S, and 155°E from 10°W to the east is the day hemisphere, and the midpoint is the direct meridian of the sun).

2) Southwest.

1) (20°S, 72 5°E) (4 points) The direct point of the sun is located on the **meridian of the diurnal hemisphere, and the range of the diurnal hemisphere is from 10°W to 155°E, and its **meridian is 72 5°E meridian; Judgment of latitude: since the meridian of 72 5°e is the meridian where the direct point of the sun is located, only the cd segment is the night at this time, that is, the range of the polar night; The cd spans latitude 20°, so the sun shines directly at 20°s.

2) Southwest (2 minutes) 15:10 (2 minutes) 155°E east to 160°E and 20°W east to 10°W (4 minutes).

3) 6 (2 points) Southeast (2 points).

1.Calculation of local time: time of the desired place = time of known place + - longitude between two places 15°) * 1 hour.

The desired location is used with "+" to the east of the known location and "-" to the west

2.Scale bar = distance on the graph Actual distance.

3.Calculation of day length: Daylight length = sunset time - sunrise time = (12 - sunrise time time) * 2

-12) *2 at sunset place

4.Calculation of the solar altitude angle at noon: 90° - the latitude difference between the point sought and the point of direct light.

(1) 110°W is 18:00, because it is the intersection of the dusk line and the equator, then 120°E is 9:20.

2) Point C is 69°N, and the date is around the summer solstice.

A At this time, it should be the summer pasture of the Tianshan Mountains, the altitude is higher, not below the spruce forest, so it is wrong B around the summer solstice, and it is not explained.

c. Around the summer solstice, it is not explained.

d North China flood season, soil salinity is low, right.

The question is the difficulty of the third year of high school, if you can't understand this explanation, then your level is really a bit poor. The key is how to swing this line on the globe, so that the application of the basics is later.

(1) From the inscription, it can be seen that 110°W is the midpoint of the dusk line, and it is also the intersection point with the equator, that is, 18 o'clock at 110°W. Beijing time: 9:20

2) If point C is 69°N, it means that there is a polar day north of 69°N, and summer is summer in the Northern Hemisphere, and the answer is D.
