Question

Слой земли 2 состоит из песка или другого материала,легко пропускающего воду. Слои 1 и 3 наоборот,водонепроницаемы. Объясните действие этого колодца. Почему вода бьёт из него фонтаном?

Answer 1

Потому что водонипроницаемые пласты давят на воду и она фонтанирует.

Answer 2

Explanation of the Well's Action

The action of the well described, where water is shooting out like a fountain, can be attributed to the different layers of the earth. According to the information provided, Layer 2 of the earth consists of sand or other materials that easily allow water to pass through, while Layers 1 and 3 are impermeable to water.

When water enters the well, it seeps through the permeable Layer 2 until it reaches the impermeable Layers 1 and 3. At this point, the water is unable to penetrate these layers and starts to accumulate. The accumulation of water creates pressure within the well. When the pressure becomes too high, the water is forced to escape through the well, resulting in a fountain-like effect.

The presence of impermeable layers above and below the permeable layer creates a confined aquifer, where water is trapped and under pressure. When a well is drilled into this confined aquifer, the pressure forces the water to rise to the surface, causing the water to shoot out of the well.

Verification of Information

The explanation provided above is based on general knowledge of how wells work and the information provided in the question. While there are no specific search results that directly support this explanation, it aligns with the general principles of hydrogeology and the behavior of confined aquifers.
