Geography Emperor, junior high school geography questions

In fact, this is a transitional knowledge linked to high school.

First of all, the selection of b continental climate characteristics, China's main is from the coast to the inland, the southeast coastal area is greatly affected by the summer monsoon and the inland area is far from the sea, the water vapor is difficult to penetrate into the continental climate, the formation of a temperate continental climate, its main characteristics are:

1.Precipitation is less, and rain and heat are at the same time.

2.The seasonal variation of precipitation is large, and the interannual variation is also large.

3.The cause is that it is greatly influenced by the Eurasian continent.

4.Winters are affected by the high pressure of Western Siberia, which is very cold and dry.

If you answer a subjective question, ask about climate, start with the causes, characteristics, precipitation characteristics, precipitation variability, solar radiation, and of course, first you have to explain what type of climate it is.

It is recommended that you buy a high school geography atlas to plan for the future.

A and d can be ruled out that the climate of our country is not complicated, and it is mainly divided into the southeast monsoon climate zone and the northwest non-monsoon climate zone. The impact of the winter monsoon is only in the coastal areas, but not in the inland areas.

B and C are both correct, but B is more in line with the stem.

The continental characteristics of climate refer to the following: high temperature and rain in summer, cold and dry in winter, large temperature difference between summer and winter, and the temperature in winter is generally below 0°C.

Taking the temperate continental climate as an example, the vegetation zone is generally a temperate deciduous broad-leaved forest zone, because deciduous trees have large green leaves in high temperature and rain in summer, which is conducive to photosynthesis and transpiration. In autumn, the leaves of deciduous trees turn yellow and fall off, leaving only the trunk and some large branches, so that when the winter is cold and dry, it can reduce water evaporation and organic matter consumption, so as to survive the harsh winter. ）

b Continental climate characterized by hot and rainy summers and cold, dry winters. The annual temperature range is large, and the precipitation is unevenly distributed in the season.

The most striking feature of a continental climate is an annual or diurnal temperature variety. So choose B

bThe annual temperature range is large, and the precipitation is mainly concentrated in summer and autumn.

Option b The temperate continental climate is characterized by cold winters, hot summers, large temperature differences, and low precipitation, mainly concentrated in summer.

b] Continental characteristics? Characteristics are characteristics that are different from other things, and continental characteristics are the characteristics of continental climate that are different from other types of climate.

The continental climate is characterized by large daily and annual temperature differences, and low and concentrated precipitation.

The answer is that the continental characteristics of option B are "large annual temperature ranges and less precipitation".

b The most striking feature of continental climate is the annual or diurnal temperature range of temperature. In the annual variation of temperature, the warmest and coldest months occur in July and January, respectively (January and July in the Southern Hemisphere). The temperature rises quickly in spring and cools down quickly in autumn, and the spring temperature is generally higher than the autumn temperature.

In the diurnal variation, the maximum temperature occurs earlier, usually at 13 14 o'clock; The lowest temperatures generally occur around dawn. Another important feature of a continental climate is the low amount of precipitation and the uneven distribution of precipitation seasonally and regionally. The regions under the influence of continental climate, which are generally arid and semi-arid, generally have less than 400 mm of precipitation, or even less than 50 mm.

b Continental characteristics are characterized by large diurnal and annual temperature ranges, uneven seasonal distribution of precipitation, and low precipitation.

North of the Earth's equator is the Northern Hemisphere. All of them are located in the northern hemisphere, North America and Europe. Within this hemisphere, land occupies and sea occupies it.

Hemisphere south of the equator. The seasons in the Southern Hemisphere are opposite to those in the Northern Hemisphere. Within this hemisphere, the land area occupies and the ocean area occupies the area.

I.1Amazon rainforest slash-and-burn farming.

2.climate change (greenhouse effect), etc.

3.Start small, start now, take care of the planet, protect our home.

2. 1) The topography of Weifang City is high in the south and low in the north, and the terrain is dominated by plains.

2) Petroleum and underground brine resources Soil salt is seriously simplified, and the conditions for the development of agricultural production are poor.

3) Industrial waste (waste gas, waste water, waste residue) The forest coverage rate is low and excessive reclamation leads to soil erosion and deterioration of the agricultural ecological environment.

The second major question is guaranteed to be correct.
