What is a glacier, can you push big rocks where there is a glacier

China's glaciers are mainly in the Qinghai-Tibet Plateau and the Tianshan Mountains in Xinjiang.

A glacier, or glacier, is a river-like landscape in which a large amount of ice is piled up. 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. Moved by gravity.

When gravity reaches a certain point, it can propel huge stones to travel hundreds or even thousands of miles.

A glacier is a natural body of ice that exists on the surface of the polar or alpine region for many years and has a state of movement along the ground.

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.

A glacier is a huge flowing solid, which is a huge glacier ice that is recrystallized and accumulated by snow in alpine regions, and the main factor of gravity makes the glacier ice flow and becomes a glacier. Glaciation involves erosion, transport, accumulation, etc., which create many terrains and form a variety of landforms in areas that have undergone glaciation. In addition, if the volume of glaciers is replaced by water, it accounts for all the amount of water on the planet except seawater.

In polar and alpine regions, the climate is very cold, and the snow is covered all year round, and when the snow accumulates on the ground, if the temperature drops below zero, it can be affected by its own pressure or recrystallized to produce snow particles, called granular snow (firn). When the snow layer increases, the snow particles are buried deeper, and the ice crystals become thicker and thicker, and the density of the snow particles increases due to the continuous decrease in the volume of air between the snow particles, making the snow particles more dense and forming blue glacial ice.

Summary. There are no glacial rocks in Antarctica. Because what we call glacial stone in China is actually a kind of granite.

There are no glacial rocks in Antarctica. Because what we call glacial stone in China is actually a kind of granite.

In China, the so-called glacial stone refers to granite with special texture stripes.

However, the foreign glacial stone refers to the stone that is transported by ice and drifts on the sea surface. Because the meaning of the object is different, it cannot be confused.

Degree. The thicker the ice, the greater the pressure, the greater the kinetic energy, and the faster the movement. When the temperature is higher, the ice is more active and moves faster. (3) The smoothness of the ground. The smoother the surface, the less resistance the glacier will move and the faster it will move, on the contrary, if.

If the ground surface is rough and uneven, the resistance is greater and the movement is slower. (4) Ice melt content. If the temperature rises, part of it.

When the ice melts into water, the melt ice content increases, the mobility increases, and the glacier moves faster (5) The glacier carries rock fragments.

impact. The more rock fragments a glacier carries, the greater the pressure, the stronger the kinetic energy, and the faster it moves.

Glaciers, as the name suggests, rivers of ice also. The difference is that the river flows like a rabbit. Originally written from.

Antarctic Glacier Facet

Glaciers are a huge erosive force, and Iceland's glacial rivers contain five times as much sand as non-glacial rivers and can be 10 or 20 times more erosive than ordinary rivers. Glaciers rely mainly on the erosion of the surface of the earth by rock fragments contained in the ice, especially at the bottom of the glacier. During the process of glacier sliding, it constantly grinds the glacier bed, an action often referred to as gouging.

In addition, the protrusion of the rock mass is loosened under the glacier due to the development of joints, which may be frozen together, and the rock is pulled out and taken away when the glacier moves, which is called erosion.

Glacier ice flows slowly down the slopes of mountains under the action of gravity (of course, very slowly), and in the process of flowing, it gradually solidifies, and finally forms glaciers.

Glaciers have a huge carrying capacity to float boulders from erosion (erodion, abrasion, ice wedges) on the ice and carry them to a distance – the carrying role of glaciers.

Glacier movement, usually the glacier is the movement of the whole block, which is relatively large, so it can move to drive boulders.

A large number of loose rock chips and debris from the slopes of the mountains will enter the glacier system, and the rock chips that are transported are called moraines, which can be divided into different types of transportation according to their different positions in the glacier

1) Moraine: The moraine exposed on the surface of the glacier.

2) Moraines: moraines sandwiched within glaciers.

3) Moraines: moraines that accumulate at the bottom of glacial valleys.

4) Lateral moraines: moraines that accumulate on both sides of glaciers.

5) Middle moraine: After the confluence of two glaciers, their adjacent side moraines are combined into one, and the middle of the glacier after the merging is called the middle moraine.

6) Terminal moraine (tail moraine): The moraine that follows the glacier and surrounds the end of the glacier is called the terminal moraine.

7) Receding moraine: Because the glacier will retreat in the process of retreating, there will be local short stays, and each stay will cause a receding moraine.

8) Drift rocks: The transport of glaciers can not only move moraines far away, but also move huge rocks to very high parts, and these huge rocks are called boulders, and their lithology is completely different from the bedrock near the place. Glaciers have a strong carrying capacity, but on the other hand, they have a poor ability to pan.
