How to do the glacier constant snow belt vegetation hand copied newspaper

The formation of glacial rivers is mainly due to the continuous erosion of glaciers and the surface under the action of gravity during the melting process of glaciers, as well as the formation of downcutting. When summer comes, the melting of glaciers forms seasonal surface rivers, and the erosion of river water is based on the continuous downward cutting of glaciers and rock spikes mixed in the river, coupled with the erosion of the source of the river, thus forming glacial rivers, and glacial rivers are seasonal.

The formation of alluvial fan plains is mainly due to the continuous development of estuarine deltas. Such as China's long-horned delta and the Pearl River Delta. All of them are alluvial fans formed by the sediment of rivers and extending to the ocean, mainly a large amount of sediment and magazines brought from the upstream.

The formation of the estuarine delta is the initial state of the development of the alluvial fan plain, that is, the prototype.

Glaciology belongs to the category of geographical sciences and is part of ice science, the science of ice in general. It includes the study of the conditions and characteristics of glacier formation, survival and development, the composition, structure and physical properties of glaciers, the geological and geomorphological effects of glaciers, the geographical distribution of glaciers, and the various interactions between glaciers and the geographical environment.

Suddenly I found that my love exploded today, hey

The list of physical geography courses is as follows:

Introduction to Earth, Surveying and Cartography, Meteorology and Climatology, Fundamentals of Geology, Soil Geography, Hydrology, Geomorphology, Plant Geography, Integrated Physical Geography, Introduction to Environmental Science, Physical Geography of China, Physical Geography of the World.

If the school is different, there may be some differences in the curriculum.

Physical geography is one of the branches of geography. The science of studying the natural environment or its components. According to the characteristics of the research, physical geography can be divided into two groups of sub-sciences: comprehensive and sectoral.

Comprehensive sub-sciences include integrated physical geography, regional physical geography, paleogeography, etc. Sectoral sub-sciences include geomorphology, climatology, hydrology, biogeography, glaciology, etc. Physical geography in the narrow sense only refers to comprehensive physical geography, and departmental physical geography has gradually developed into an independent discipline.

Physical geography in the narrow sense refers only to comprehensive physical geography.

The courses include Introduction to Earth, Surveying and Cartography, Meteorology and Climatology, Fundamentals of Geology, Soil Geography, Hydrology, Geomorphology, Plant Geography, Integrated Physical Geography, Introduction to Environmental Science, Physical Geography of China, Physical Geography of the World, etc.

To put it simply, geography covers a wide range of areas, such as geology, astronomy, maps, GIS, geomorphology, urban geography and human geography, etc., but geology is relatively more professional, mainly studying strata, ores, etc., and other aspects are rarely involved but have a higher degree of specialization.

If you want to study glaciers, there is no special major at the undergraduate level, and you can find out which scientific research institutes are good at glacier research, and you will generally specialize in research at the master's and doctoral levels.

Geography and geology can be examined, but the two majors have different directions for glacier research, geology is mainly Quaternary geology to study glaciers, geography includes two major blocks, physical geography and human geography, it rarely studies the earth from the nature and movement of matter, geology is the study of the earth's material composition, structure, structure, formation and evolution of science.

A glacier is a landscape in which a large amount of ice accumulates to form a river-like landscape. In alpine or polar regions that are frozen all year round, glaciers are formed by gravity or interglacial pressure that results in snow that slides down the slopes.

Glaciers are formed by the accumulation of snow for many years, which is formed by ice formation such as compaction, recrystallization, and refreezing. It has a certain shape and layer, and has plasticity, under gravity and pressure, produces plastic flow and block sliding, and is an important freshwater resource on the surface. International Glacier Inventory Regulations:

All perennial snowdrifts and ice bodies with an area of more than square kilometres should be included in the glacier inventory.

Glaciers are a form of water that is transformed by snow through a series of changes. To form a glacier, there must first be a certain amount of solid precipitation, including snow, fog, hail, etc. Without enough solid precipitation as a "raw material", it is equivalent to "cooking without rice", and it cannot form a glacier at all.

Glacier definition: A natural ice body with a certain shape and self-movement formed by metamorphism after years of snow accumulation in cold regions.

To put it simply, Quaternary glaciers caused the separation of originally continuous biological populations. As a result, the large population was divided into small species of large cherry blossoms that could exist with a certain degree of reproductive isolation, thus bringing about diversity. Wish.

The answer to this question is DThe number of vegetation types has increased.

To explain: First of all, you need to be clear that the background of the continued large-scale melting of the world's glaciers must be global warming, or at least the increase in the temperature of the glacier Earth.

Melting glaciers lead to a rise in sea levels, which inundates coastal plains and reduces their size. Therefore a error.

After the glacier melts, the fresh water brought by the glacier melt will greatly increase the amount of fresh water on land, so it is bfalse.

Melting glaciers indicate higher temperatures, which in turn lead to lower air pressure at the poles. (hot low pressure, cold high pressure), so c is wrong.

The continued large-scale melting of glaciers around the globe indicates that the temperature is rising, and at the same time the surface water is increasing, which will inevitably increase the type of vegetation on the planets around the world.

Choice C is because the glaciers melt on a large scale, the altitude of the polar regions will decrease, and the natural air pressure will also increase. aObviously wrong, the plains shrink when there is more water; b is a meaningless option, because it has no effect on the freshwater on land, and it will increase if it is just to be said, because the larger the ocean area will increase the moisture; D is even more incorrect, the land area is less, and the vegetation type will be reduced.

This "like geography problem" geography knowledge is very solid, learn!

Upstairs is the right solution. Pick D

On the third floor, don't just see that the source of fresh water is atmospheric precipitation, and glacial meltwater is also an important one.

As the temperature rises, the polar high pressure will definitely weaken. For example, the equatorial low pressure is the same!
