In the Northern Hemisphere, on July 13, the days and nights are shorter and shorter as you get closer to the direct point of the Sun or longer to the Arctic Circle.

- Look at the closer you get to the Arctic Circle, the longer it gets!

On June 22, the sun shines directly on the Tropic of Capricorn, and the polar day is in the upper circle of the Arctic Circle, and the polar night is in the upper circle of the Antarctic Circle. For more than a month before and after June 22, the days get longer the farther north and the closer you get to the Arctic Circle, the longer the days become.

In fact, after March 21 and September 23, the days are longer and the nights are shorter in the Northern Hemisphere, and the closer you get to the Arctic Circle, the longer the days become. It's just that the length of the days and the shortness of the nights in late March, April, and early to mid-September are not obvious, and it is not easy for people to feel them without instrumental recording.

So, comparing the length of day and night is not to look at the position of the direct point, but.

Take a look at the solar terms – the seasons (mainly to see the summer solstice, summer or the winter solstice, winter). The summer solstice (summer) gets longer and shorter nights the further north you go; The winter solstice (winter) gets longer and shorter nights and shorter days the further north you go.

Second, look at the distance from the Arctic Circle. The summer solstice (summer) gets closer to the Arctic Circle, the longer the days and the shorter the nights; The winter solstice (winter) gets closer to the Arctic Circle, the longer the nights and the shorter the days.

Inarticulate. In summer, the higher the latitude in the Northern Hemisphere, the longer the daylight.

It's not about the point of direct fire.

If it is 20 degrees north latitude, then the day at 25 degrees north latitude is obviously longer than the day at 19 degrees north latitude, so it is wrong to get closer to the point of direct light. And at the same latitude, the day length is the same.

So according to your question, the closer the Arctic Circle is, the longer it gets.

Of course, the higher the latitude, the longer it is.

The closer you get to the point of direct sunlight, the longer it gets. Northern summers, for example, have more sunlight on the summer solstice than elsewhere on the equator.

In July, it's summer in the Northern Hemisphere, and the farther north you go, the longer the daylight. In the Arctic Circle, the sun does not set at all.

1. The straight-line distance is about 1200 kilometers.

2. It passes through Tianjin, Jinan, Shijiazhuang, Zhengzhou, Hefei, and other cities, and the provinces include Hebei Province, Henan Province, and Hubei Province.

3. I'm sorry, I really don't know what mountains and rivers I have. There's no need to be so detailed about this geography. Allow me to be lazy.

4. Take the train from Wuhan to Beijing, there are two places to get on the train, Wuchang and Hankou. It takes 10 hours for a direct train, 13 hours for a T80, and about 2 hours for a plane.

It's not that you're not geographically good, it's lazy!

1. Just find a map and measure the straight-line distance with a ruler, and multiply it by the scale.

2. You can count it on the map.

3. It can also be seen by looking at the map.

4. Check a plane (non-stop) casually, look at the departure time and arrival time and come out.

It's the same with trains. This is all found in online merchants. Compared to you, you can surf the Internet.

To add, there are too many rivers to cross, countless big rivers and small rivers, there must be a standard.

Select B, C, and D

1) There are many types, including almost all types of natural disasters in the world. Among all kinds of disasters, floods, droughts and ** are the most harmful.

2) Disasters occur frequently, intensively, and with serious losses. China is known as "three years old one starvation, six years old one decline, twelve years old one famine".

3) The spatial and temporal distribution is wide, and the regional combination of disasters is obvious. The spatial distribution and regional combination of natural disasters in China have a strong correlation with the regional differences in natural and socio-economic environment. In terms of macro distribution, the droughts that mostly occurred in spring and autumn were mainly distributed in Northwest China, the Loess Plateau and North China. The heavy rains and floods that mostly occur in summer are mainly distributed in the vast eastern monsoon region, concentrated in the seven major river basins. Forest fires are mainly distributed in the northeast and southwest forest areas, and most of them occur in the dry season of winter and spring. **Mainly distributed in the active tectonic belts of southwest, northwest and north China; Low temperature frost damage and ice and snow disasters are particularly prominent in the Qinghai-Tibet alpine current area. Typhoons and storm surges mostly occur in the southeast coastal areas.

Southwest is accompanied by heavy rain and causes landslides, collapses, debris flows and flash floods. The spatial distribution of natural disasters also shows a certain degree of conjugation.

BC The main characteristics of natural disasters in China are that there are many types of disasters, wide distribution areas, high frequency of occurrence, and heavy losses.

That's a good calculation.

Point C is the sunrise at 6 o'clock, point B is the sunrise at 4 o'clock, and point A is the sunrise at 2 o'clock, with a difference of 2 hours each. Point C is on the equator, day and night are equinox, and the length of day and night is 12 hours.

The sunrise at point B is 2 hours earlier than that at point C, and of course the sunset is 2 hours later than point C, and the day length is 12 4 16 hours of sleepiness.

The sunrise is 2 hours earlier than the point B, and the sunset is 2 hours later, and the day length is 16 4 20 hours. Correspondingly, the length of the night is only 4 hours.

It means that this is summer in the Northern Hemisphere, and point A is very close to the Arctic Circle.

21. (3) The river flows radially from the middle to the periphery;

4）d，e。

22. (1) Volga River;

3) There are many species and uneven distribution, mainly distributed in the Asian part, rich in mineral, forest and water energy resources.
