As an expert in the field of geothermal energy and environmental science, I can provide a detailed explanation regarding the temperature conditions underground. The temperature underground is influenced by several factors, including the geothermal gradient, the season, and the local geological conditions.
Geothermal Gradient: The geothermal gradient is the rate at which temperature increases with depth in the Earth's subsurface. On average, for every 100 meters (or approximately 328 feet) you descend into the Earth, the temperature increases by about 25 to 30 degrees Celsius (or 45 to 54 degrees Fahrenheit). This increase is due to the heat generated from the Earth's core radiating outward.
Seasonal Variations: While the geothermal gradient provides a general trend, the temperature underground can also be influenced by seasonal changes. In winter, the surface air temperature drops significantly, but the temperature underground remains relatively stable. This is because the soil and rock act as insulators, retaining heat from the warmer seasons. As a result, it can feel warmer underground compared to the cold surface air.
Local Geological Conditions: The local geology plays a crucial role in determining the temperature underground. Different types of soil and rock have varying thermal conductivities, which affect how heat is transferred. For instance, clay has a higher thermal conductivity than sand, meaning that heat is transferred more efficiently through clay. Additionally, the presence of water can also affect the underground temperature. Water has a high heat capacity, meaning it can absorb and store a significant amount of heat, which can then be transferred to the surrounding soil and rock.
Heat Absorption by Fluids: As you mentioned, the liquid or solution circulating through pipes in the ground can absorb heat from the ground. This is the principle behind geothermal heating systems. These systems take advantage of the relatively stable and warmer temperatures underground to provide heating for buildings. The fluid circulates through a heat exchanger, which transfers the heat from the ground to the building's heating system.
In conclusion, whether it is warmer underground depends on the depth, the time of year, and the local geological conditions. Generally, underground temperatures are more stable than surface temperatures and can be warmer during the winter months due to the insulating properties of the soil and rock. The use of geothermal energy for heating is a testament to the consistent warmth that can be found underground.

In winter, when it is cold outside, the temperature underground is warmer than the air. The liquid, or solution, circulating through the pipes in the ground absorbs heat from the ground.
