Knowledge points on the earth's surface

The face of the earth refers to the characteristics and forms of the earth's surface, including topography, climate, hydrology, biology and natural landscape.

topography

Mountain: The hills and mountains on the earth's surface are a landform, including geophysical phenomena such as plate movement and crustal movement. These mountains are often formed by plate collision, crustal uplift, geological processes and other factors.

Plain: Plain is a relatively flat and wide area on the earth's surface, which is usually formed by river alluvial and transgression. Plain area is usually rich in agricultural resources and population distribution, and it is an important area for human activities.

Desert: Desert is a kind of landform in the arid area of the earth, among which the Sahara desert is the most representative. There are many reasons for the formation of desert, including geographical location, climate, landform structure, human activities and so on.

climate

Climate is a kind of weather phenomenon appearing on the earth's surface, which is influenced by many factors, such as geographical location, land and sea distribution, atmospheric circulation and so on. Climate types are diverse, including tropical rain forest climate, tropical desert climate, temperate maritime climate and polar climate.

Global climate change is also an important knowledge point, and the impact of human activities on climate and global warming is an important direction of current scientific research.

hydrology

Hydrology refers to the water cycle on the earth's surface and the characteristics of rivers and lakes. Water is the source of life, and hydrological characteristics are of great significance to human life and ecosystem.

Rivers are an important part of hydrological characteristics, and the formation of rivers, basins and valleys is also the focus of hydrological research.

Biological and natural landscape

There are rich and colorful biological communities and natural landscapes on the earth's surface, and these natural resources are an important foundation for human survival and development. Biodiversity refers to species diversity, genetic diversity and ecosystem diversity.

Natural landscape refers to the unique natural geographical phenomena on the earth's surface, such as forests, grasslands, wetlands and glaciers. These natural landscapes are not only of scientific value, but also important places for people to visit.

Expand knowledge:

Natural disasters refer to abnormal phenomena in the natural environment, such as earthquakes, volcanic eruptions, floods and typhoons. These disasters may bring serious loss of life and property to human beings, so they are also important knowledge points for disaster prevention and mitigation.

Environmental protection is one of the important problems facing mankind at present, and the protection of natural resources and the sustainable development of ecological environment is also an important direction of current scientific research. Environmental protection involves not only natural science, but also sociology, economics and management.

Sustainable development refers to a development model that can meet the current human needs without damaging the ability of future generations to meet their needs. The core of sustainable development is the coordination between economic development and environmental protection, emphasizing long-term planning and management of natural resources protection and utilization, and promoting long-term economic and social development.

Climate change and environmental problems are global and transnational, and international cooperation plays an important role in dealing with these global challenges. Global environmental governance needs the participation of governments and international organizations to jointly deal with global environmental problems through policy formulation, international cooperation and technology promotion.

In a word, the knowledge of the earth's surface involves all fields of the earth's surface, including topography, climate, hydrology, biology and natural landscape. By deeply understanding the face of the earth, we can better understand the evolution process and natural laws of the earth, and also provide scientific basis and support for environmental protection and sustainable development.
