Why is it that the rocks on the mountain are usually full of cracks, but the foot of the mountain is

The cracks in the rocks on the mountain are formed by weathering over many years of wind and sun.

On rainy days, the rain washes down the rocks on the mountain.

The rocks on the mountain were weathered and blown to the foot of the mountain.

Because it must have been a broken stone from the rocks of the mountain.

Because of the frequent human activities at the foot of the mountain.

Because of the long period of time, there will be a certain amount of geological movement.

Because sometimes there is some geological movement.

Gravel will fall down the mountain,

There will be a lot of natural forces at work on the mountain.

Gravel fell from the mountain.

1. The role of cold and heat.

2. The role of running water.

3. The role of plants.

4. Animal activity.

There are three types of rocks in nature, stacked rocks and igneous rocks.

and metamorphosis rocks. Igneous rocks are the path of magmatic intrusion or eruption, according to the chemical composition, mineral composition, there are many varieties, such as granite, andesite, basalt.

Wait. Metamorphosis is a variety of rocks that are subjected to high temperature and high pressure, such as marble and gneiss.

Stacked rocks are rocks formed by weathering, denudation, re-migration and accumulation, such as sandstone, conglomerate, etc. These different varieties of rocks make up the mountains of the various mountainous areas. The details of what type of rock you are are depend on the state of practice.

Some volcanoes erupt into mountains, then igneous rocks are dominant.

Regardless of the type of rocky mountain range, the rock itself produces some fissures, especially igneous rocks, which are called cleavage in geology, such as basalt hexagons.

Cleavage. In addition, due to the influence of the geotic stress field, the plate is extruded, and the rock will burst, and the rock will form cracks or faults.

These crevices further provide a thin spot for weathering. Weathering is the process of rock synthesis under natural conditions such as wind, light, water, acids, etc. As a result, cracks along the slopes are most susceptible to weathering, and the product of weathering – debris – can roll down to the base of the hill by gravity, or accumulate at the base of the hill under the wash of the current.

Lives in South America.

The ancient Indians used water to freeze and split mountains and rocks. When the temperature drops below zero, the water in the crevices freezes, and at the same time exerts great pressure on the rocks that prevent them from shrinking, so that the rocks are split.

When you go out, you must pay attention to safety, some slack mountains, in heavy rainfall.

, mudslides will be generated.

Large rocks may also suddenly loosen and roll down to the bottom of the mountain. Therefore, the homework before the tour is essential, when visiting a certain mountainous area, you must do the geological and climatic homework there in advance, just in case, to yourself, to your family!

Due to the change in temperature, the mountain rock expands and contracts in heat.

Make the mountain unavoidable to present gaps. It is not uncommon for precipitation in nature to flow into the cracks of mountains and freeze in the cracks. Therefore, it is normal for gravel to appear at the foot of the mountain.

Because the rocks on the mountain have been weathered, they are full of cracks, and after a long period of weathering, the rocks on the mountain will crumble and slowly accumulate at the base of the mountain.

This is due to gravity, which causes the rock to roll downward, and in the process of tumbling, it collides, and the whole structure disintegrates.

This is because for the rocks on the mountain, they have been exposed to wind and sun for many years, and have been formed by a series of weathering, and in this process, the rocks will slowly break up, and under the action of relative gravity, they will be piled up at the foot of the mountain to form gravel.

Many people say that Guilin's mountains and rivers are the best in the world, but in fact, Guilin's water is indeed the best in the world, but the mountains are not necessarily. If you go to the 700 Lane in Guangxi, you don't think so, because it is the sea of mountains. When you stand on the top of the mountain and look at it, the entire 700 alleys are vertical and horizontal, and thousands of peaks are showing, towering high and low.

At this time, the mountain seems to have an aura, and the illusion is endless.

Those who have never been to 700 Lane may not be able to appreciate the suffocating churning in their lifetime. According to the data, there are more than 9,000 peaks above 800 meters above sea level in Qibai Lane, with an average of 19 per square kilometer, which can be said to be one of the most dense areas in the world. It's a great place for hikers and hikers, but if you want to climb the mountains, it will take you more than 20 years.

Lotus Mountain is one of the thousands of stone mountains in 700 lanes, located in Shuangfu Village, Duyang Town, Dahua County, surrounded by 5 big stone mountains in the east, west, south and north at an altitude of more than 1,000 meters, from a distance, it resembles a lotus. The strange thing is that among the thousands of stone mountains in Qibai Lane, the top of the mountain is bare, but this Lotus Mountain is different, although it is one of the highest mountains in Qibai Lane, but the top of the mountain is full of trees. What's even more interesting is that there is a spring here, and over the years, droughts and floods have not dried up.

Passing through the archway gate at the foot of Lotus Mountain, climbing up from the bottom of the mountain, the mountains you see along the way are bare at first, not a single big tree grows, and even the dwarf miscellaneous trees are very few. But when you walked more than ten kilometers of mountain road and climbed to the top of the mountain out of breath, you suddenly saw a small mountain village in the alley of a few square kilometers below.

Dozens of houses are criss-crossed, nestled in the lush woods, with herds of farmhouses, mountains of cattle and sheep, smoke curling from cooking, and a few children chasing after each other. The Buddhist hall, the scripture building, and the pavilion on the mountain are hidden in the green trees and flowers. Could this be the legendary "paradise"?

It's like trekking hundreds of miles in the vast desert Gobi and suddenly seeing an oasis, how can it not be amazing that there is such a wooded place hidden on such a barren mountaintop?

Although it is on the top of the high mountain, there is a spring on the top of Lotus Mountain, called "Smart Spring", the spring water is crystal clear, drought and flood do not dry up, I don't know where these water comes from. Local residents go up to the mountains to collect spring water as a medicinal solution to drink or bathe, and it is said that it can also cure diseases with local Chinese medicine.

Many tourists may want to ask, most of the mountains here have the word "lane", such as "lane ear mountain", why is it called Lotus Mountain? Could it be that the mountain alleys are full of lotus flowers?

Local villagers told me that the topography resembles a giant lotus flower blooming brightly. It is surrounded by 5 mountain peaks, and these 5 peaks are like 5-petal lotus flowers, with such a magical alley (basin) in the middle.

In the evening, standing on the Lotus Mountain, the distant peaks are like thousands of galloping horses, galloping in the sunset. With such beautiful mountains and thousands of "lanes", don't you want to come and see them?

This is well understood, there are two ** in the rock cracks in the mountain: 1tectonic joints, fractures produced by stress in rocks (generally with a specific direction and very neat); 2. Weathering fissures, as the name suggests, are cracks formed by weathering without a specific direction (generally the cracks are smaller).

As the weather progressed, the cracks grew larger and larger, and some of the stones rolled down from their original heights and piled up at the foot of the mountain.

Because the impact force of the stones at the foot of the mountain is greater, especially when there is a flood, the large stones are washed down from the mountain by the flood, and the major impact force formed is easy to break the stones. Moreover, the earth is in constant motion, and when the earth's crust moves violently, the stones on the mountain will roll down, breaking the stones at the foot of the mountain.

Due to the high position of the stones on the top of the mountain, they are less affected by the human factors below the mountain, and it is easier to preserve them completely. The stones at the foot of the mountain have been damaged by pedestrians or other factors, and it is not easy to preserve them intact.
