How did the desert oasis and mirage come about?

A mirage is a true embodiment of another space. Under the movement of matter, it is reflected in our space. A type of mirage occurs at sea.

The air humidity here is large, and the air humidity in the space within a certain range is relatively large, and the thickness is relatively large, so that a large area of water vapor can form a huge lens system by mistake under the movement. It's like a giant magnifying glass and microscope, reflecting the scene of another dimension of the microscopic world into our space. The human eye can see it.

In addition, the mirage that people see is sometimes in motion, and the matter of the space is in motion. In the desert or elsewhere, if matter can form a huge microscopic observation system under motion, people can observe another space, which is called a mirage.

In addition, mirages often occur after rain, when the air humidity is high and it is easy to form a lens system.

In places such as calm seas, rivers, lakes, snowfields, deserts or the Gobi, there are occasionally illusions such as tall buildings, city outlines, and trees in the air or "underground", which is called mirage, also known as "mirage". The ancients attributed the mirage of the genus of the dragon to exhale into the outline of the tower, hence the name. <>

In the bare desert with drought and little rainfall, you can also find an oasis full of water and grass and green trees. How did this oasis come about? In the summer, the snow and ice in the mountains melt and flow down the slopes to form rivers.

When the river flows through the desert, it seeps into the sand and becomes groundwater. This groundwater gushes out of the ground after flowing along impervious rock formations to the low-lying areas of the desert. In addition, rainwater from afar seeps into the ground and can also merge with groundwater to flow into the low-lying areas of the desert.

Or due to changes in the earth's crust, impermeable rock formations are fractured, causing groundwater to flow along the cracks to low-lying desert areas and wash out of the ground. With water in this low-lying area, all kinds of organisms emerge, develop and reproduce. <>

On a calm sea, it is common to see distant images of ships, islands, or castle towers reflected in the sky. When the wind blows, these images disappear, and this is what people call a mirage. This is because the light rays travel in a straight direction within a uniform medium of the same density.

When the air temperature is abnormally distributed in the vertical direction, it will cause an abnormal air density, so the light from the object will be refracted or fully reflected in the air, and the phenomenon of mirage will appear.

A mirage is a hallucination caused by a heat, exhaustion, and extreme lack of water. There are basically no mirages in the city.

There are also mirages in cities, but they are more common in the desert, where people tend to reach their limits, resulting in a lack of clarity, and the wide sky over the desert is conducive to the formation of mirages.

Possibly, a mirage is an illusion that occurs when people are too hot, and if the temperature in the city reaches fifty or sixty degrees, it is possible to see a mirage in the city.

Mirage is an optical phenomenon in which hot air rises on the sandy or stony surface, and light refraction will form a mirage, which can also occur in the city, and once appeared in the sky over the city of Xiamen.

Mirages often occur in seaside and desert areas, as well as in polar ice fields. The reason for this is that the drastic temperature gradient changes heterogeneously, which causes the light to refract significantly at the temperature difference. When the optical fiber is refracted and there will be a strange scene in the air or on the ground, also known as a mirage, which is what we call a mirage.

There are upper and lower mirages. Now is the meaning of manifestation.

Upper mirages are often found in areas such as snowy fields and cold oceans. These areas are cooled near the surface, creating a dramatic temperature gradient of hot at the top and cold at the bottom. Due to the refraction of the atmosphere, the scene of the ground is lifted upwards and displayed in the air, and it seems that distant objects appear to be at a certain height in the sky, and even distant scenes below the horizon can be seen.

Mirages often occur over waters, land, seashores, and highways that are strongly warmed by the sun. The warming of the earth's surface creates a violent temperature gradient of cold at the top and hot at the bottom, so that the physical scene on the ground is refracted below the ground. This mirage is often inverted, and the scene has strong shaking.
