Division of seven temperature zone of that earth

The seven temperature zones of the earth are divided according to the characteristics of temperature and climate. They are tropical zone, north temperate zone, south temperate zone, north frigid zone, south frigid zone, north subtropical zone and south subtropical zone.

This gives us an idea of the tropics. Tropical refers to the region with the longest sunshine time and the highest temperature on both sides of the equator. Therefore, the tropical climate is characterized by high temperature, rainy and high humidity. Tropical rain forest is the most common vegetation type in tropical areas, because the climatic conditions here are very suitable for plant growth.

Followed by the north temperate zone and the south temperate zone. These two temperature zones are located in the north and south of the tropics, and the sunshine time and temperature are relatively low. The climate characteristics of the north temperate zone and the south temperate zone are distinct seasons and large seasonal variation of precipitation. There are various vegetation types in these areas, from tropical rain forests to cold coniferous forests.

Then the northern cold region and the southern cold region. These two temperature zones are located in the northernmost and southernmost parts of the earth, and the temperature is very low because of the shortest sunshine time. The climatic characteristics of the northern and southern cold regions are covered with snow and ice almost all year round. There are few kinds of creatures here, and only some animals and plants that adapt to the cold environment can survive.

Finally, the north subtropical zone and the south subtropical zone. These two temperature zones are located between the north temperate zone and the north frigid zone and between the south temperate zone and the south frigid zone. Their climate is characterized by high temperature and rain in summer and mild and little rain in winter. The vegetation types here are mainly evergreen broad-leaved forest and deciduous broad-leaved forest.

Impact of global climate change:

1, natural environment: climate change leads to changes in the natural environment. Global temperature rise leads to the melting of polar glaciers, which in turn leads to sea level rise, which will pose a serious threat to coastal cities and island countries. At the same time, climate change will also have an impact on biodiversity, and many species may become extinct because they cannot adapt to the new environment. In addition, climate change will trigger more extreme weather events, such as floods, droughts and storms. , will pose a threat to human living environment and the safety of life and property.

2. Agriculture and food security: Climate change has a great impact on agricultural production and food security. On the one hand, climate change will lead to an increase in extreme weather events such as drought and floods, which will adversely affect agricultural production and reduce food production. On the other hand, with the increase of temperature, the incidence of diseases and insect pests will also increase, which will bring greater challenges to agriculture. In addition, soil degradation and desertification caused by climate change will also have a negative impact on agriculture.

3. Socio-economy: The impact of climate change on socio-economy cannot be ignored. First, climate change will affect the production and distribution of energy. Extreme weather events such as drought and flood will destroy energy infrastructure such as hydropower stations and nuclear power plants, thus affecting energy supply.

Secondly, climate change will also have an impact on transportation, such as extreme weather events, such as ice and snow and floods, which will lead to traffic disruption and delay. Finally, climate change will also have an impact on tourism. Extreme weather events such as drought and flood will destroy tourist attractions and facilities, thus affecting the income of tourism.
