The ground is heated by the sun's rays penetrating the Earth's atmosphere and warming the surface. The heat is absorbed by the ground and retained, which contributes to the overall temperature of the Earth's surface.
Groundwater heated by magma can form geysers, where the pressure from steam and boiling water builds up underground until it forcefully ejects through the surface in a powerful spray. This process is what creates geothermal features like geysers and hot springs.
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.

A Geyser can develop. It can also be a source of energy, i.e. Hydrothermal Energy.

The process of bubbles escaping the surface of a heated liquid is called boiling. It happens when the liquid reaches its boiling point and the vapor pressure equals the atmospheric pressure, causing bubbles to form and rise to the surface.

Superheated water from under the ground is known as geothermal water. It is heated by the Earth’s internal heat and can reach temperatures higher than the boiling point at the surface due to high pressure conditions. Geothermal water is often used in geothermal power plants for electricity generation or in geothermal heating systems for homes and buildings.

Hot springs or geysers are created when groundwater gets heated by hot intrusive rocks and can ascend via fractures in the crust. In the most extreme case so called phreatomagmatic eruptions take place. When magma ascends and reaches groundwater at shallow depths, the resulting steam expands dramatically and fractures the overlying rock thus producing a conical hole in the ground. These volcanic craters are referred to as maars.
If it is heated.
The air just above the ground is typically heated by conduction, as the ground absorbs heat from the sun and transfers it to the air molecules in direct contact with the ground surface. This process creates warm air near the surface, which then rises due to its lower density compared to the surrounding cooler air.
When magma cools you get intrusive igneous rock. Think of other ig words you know. Ignite, ignition they all mean heat. Igneous rocks are formed from rocks that have been heated so much they melt. When they cool they make new, igneous, rocks. If it's magma that cools that means it's still under the earth's crust so the igneous rock is intrusive. If it's lava that cools after flowing down a volcano it's an extrusive igneous rock that's formed.
