The southern part of Russia is mountainous in Asia, but the Trans-Siberian Railway was built along the southern mountainous region because of some differences in climate.

The north, near the Arctic Circle, was colder and froze the railroad. It is said that when it is cold in Russia, the iron rods outside can freeze off!

Due to the limitations of natural and technical conditions, it is not always suitable to go to Antarctica.

Target. The time for expeditions and expeditions to Antarctica should be chosen in the winter of the Northern Hemisphere, because the Antarctic region is at this time.

It is summer, which is the season with the longest polar day or daylight and the highest temperature. Midsummer on the coast around the Antarctic continent.

The highest temperature in the region can reach 7° 8, and the lowest temperature is -17, which is warmer than Beijing in January; Same.

When the summer in Antarctica is mostly sunny and sunny, it is the "best season" for scientific investigations, and the annual material and personnel replacement are mainly carried out in this season. The first scientist in our country.

The time to build a station in Antarctica is also to choose this season.

Largest: Russia, Canada, China, the United States.

Most populous: China, India, USA, Indonesia.

February is cold in the Northern Hemisphere but warm in the Southern Hemisphere, so it should be in February.

1.The largest areas are Russia, Canada, the People's Republic of China, and the United States.

The most populous are China and India, but I don't know about the future.

2The north is close to the Arctic Ocean, the temperature is low, and most of it is frozen soil, which is not conducive to the construction of railways!

3 Our country is in the northern hemisphere, the northern hemisphere is in winter in February, and the southern hemisphere is summer in February! More daylight hours than night time is conducive to the work of scientific research personnel!

Russia, the United States, China, Australia.

1.The water vapor contained in the breath turns into small droplets. Because the temperature on the glass is low, the water vapor condenses.

2.The weather is cold and the temperature is low, the water vapor contained in the air is close to saturation, the evaporation is small, and the moisture in wet clothes is difficult to be evaporated into water vapor.

3.Rivers, groundwater, after treatment, tap water.

Supplement: Because the darker the color, the more heat absorbs from the sun's rays. If the outer wall of the louver box is painted black or dark, its temperature will rise rapidly in the sun, so that the air temperature in the box will increase, and the air temperature and humidity we measure are not the temperature and humidity of the air in the shade, but the temperature and humidity after being heated by the sun, which is not representative.

The outer wall of the louver box is painted white, and the sunlight projected on the louver box will be reflected off by the white surface, so that the air in the box will not be baked very hot due to the heating of the box wall, and the measured temperature and humidity are representative, so the outer wall of the louver box must be painted white.

Dear, the first three questions are biology questions, right? The seventh grade book is on the winter vacation paradise.

Saturation of condensation.

Ground floor. Rivers.

Supplements red endothermic (infrared).

The temperature will be higher than the actual temperature.

1 A white mist will appear on the surface of the glass because the air exhaled by the human body is hot and contains a lot of water vapor. When it encounters glass with low temperatures, water vapor condenses, and white fog appears.

2 There are several conditions for clothes to dry quickly: large air circulation; Large humidity difference; The temperature is higher. In a cold and humid environment, it is difficult for the moisture of wet clothes to be carried away by the air, but it is easy to condense moisture.

3 The main sources of water used for human activities are rivers, lakes and groundwater.

The louver box is used to measure the air temperature and humidity, and the paint white is mainly to reflect the sunlight to avoid the high temperature of the box and interfere with the temperature measurement. The red color just absorbs the heat of the sun, which will increase the temperature of the box.

white, Arab, Islamic; Mecca, the holy city.

Jewish, Jewish; Persia, Islam; Islamic. Azerbaijan, Armenia, Georgia, Arabia.

Security, Legal, Diplomatic, Finance.

1. The people in the Middle East are mainly white, and the residents of most countries and regions are mainly Arabs and believe in Islam; Mecca in Saudi Arabia is revered as the "Capital of Religion" and "Holy City".

2 The Jews (also known as the Hebrews) were concentrated in Israel, and believed in Judaism; The Persians are mainly found in Iran and believe in Islam; Turks are mostly Muslims. The three countries mentioned above, as well as Georgia, Armenia and Azerbaijan, which became independent from the Soviet Union, are not Middle Eastern countries.

3 The EU member states are closely linked to each other, and they maintain considerable consistency in the fields of agriculture, currency, fisheries, **, politics, diplomacy, etc.

Hello, the answer you want is:1yellow, Arabic; Islam; Mecca, the religious capital of "Al-Quds".

2.Jew; Judaism; Persia; Islam, Islam, Georgia, Armenia, Azerbaijan, Arab countries.

3.political, economic, military, and cultural .

On the way, fill in the names of the stars, fill in the Earth's axis, equatorial plane, the Earth's orbital plane (ecliptic plane), the direction of the Earth's rotation (drawn with arrows), and note the number of angles between the Earth's axis and the orbit - as shown in the figure.
