Answer:
Groundwater systems are formed by the permeable layers of soil and rock that allow water to flow through them. When this water is heated by the Earth's internal heat, it can rise to the surface and release heat into the air above. In the case of a school, if the school is located near a groundwater system, the heated water from the system can potentially heat the air in the school. This occurs because the warm water rises and releases its heat into the air, causing the air temperature to increase. This is known as geothermal heating and it is a natural process that can be harnessed for heating purposes. If the school is designed to take advantage of this heating source, it can provide a more energy-efficient and environmentally friendly solution for heating the air in the school.
