Як діють гейзери??ответ срочно надо​

Answer 1

Ответ:

При підніманні води вгору по каналу тиск її меншає і вода закипає; при цьому швидко зростає пружність пари, яка, долаючи тиск води в каналі, викидає воду. З початком фонтанування гейзера вся вода в каналі закипає і вивергається за рахунок значного збільшення об'єму пароводяної суміші. Викинута вода, дещо охолоджена, частково падає в чашу гейзера. і попадає в його канал. Більша частина води просочується в канал з бічних порід, нагрівається (а в нижніх частинах каналу перегрівається), і знов відбуваються утворення пари і викид пароводяної суміші.

How do geysers work?

Geysers are natural geological features that periodically erupt hot water and steam into the air. They are formed when underground water becomes superheated and erupts through a vent to the surface. Here's a detailed explanation of how geysers work:

1. Underground Water Reservoir: Geysers are typically found in areas with volcanic activity, where there is a reservoir of underground water. This water is heated by geothermal energy from the Earth's interior.

2. Heat Source: The heat for geysers comes from magma chambers or hot rocks deep beneath the Earth's surface. This heat warms the water in the underground reservoir.

3. Confining Pressure: The underground water is under significant pressure due to the weight of the overlying rocks. This pressure prevents the water from boiling at its normal boiling point.

4. Superheating: As the water is heated, it reaches a temperature above its boiling point but remains in a liquid state due to the confining pressure. This is known as superheating.

5. Nucleation Sites: Within the geyser's vent, there are small channels or constrictions that act as nucleation sites. These sites provide a starting point for the formation of steam bubbles.

6. Trigger Mechanism: The eruption of a geyser is triggered by a combination of factors, such as the accumulation of steam bubbles, the pressure build-up, and the release of a small amount of water from the vent.

7. Eruption: When the pressure becomes too great, the superheated water rapidly boils, creating a surge of steam and water that is expelled through the vent. This eruption can reach heights of tens of meters.

8. Recharge Period: After an eruption, the geyser's underground reservoir needs time to recharge with water and heat. This period can vary from minutes to hours or even days, depending on the geyser.

9. Cycle Repeats: Once the reservoir has recharged, the cycle of heating, superheating, and eruption begins again.

It's important to note that each geyser has its own unique characteristics, and the specific details of their eruptions can vary. The famous Old Faithful geyser in Yellowstone National Park, for example, erupts approximately every 90 minutes and can reach heights of up to 56 meters.
