Main sources of internal heat are Magmatism and Radioactivity.

Source from which energy can be obtained to provide heat, light, andpower. Sources of energy have evolved fromhuman and animal power to fossil fuels, uranium, water power,wind and the Sun.
The primary sources of energy on Earth are the sun and the Earth's internal heat. Solar energy drives weather patterns, ocean currents, and photosynthesis in plants. The Earth's internal heat, from radioactive decay and residual heat from its formation, powers geothermal energy sources.
Earth's internal energy sources include residual heat from its formation, radioactive decay of elements like uranium and thorium in the mantle, and the heat generated by the solidification of the inner core. These sources drive processes like mantle convection, plate tectonics, and volcanic activity.
What is internal and external sources?
The two main sources of Earth's internal heat energy are residual heat from the planet's formation over 4.6 billion years ago and the decay of radioactive isotopes within the Earth's mantle. The heat generated by these processes contributes to the movement of tectonic plates and drives geological activity on the planet.
The sun
Examples of heat sources could be grouped into two (2) based on there origin. They are; 1. Natural Heat Sources. The natural heat sources could be sub-divided into two; a. External Source, e.g Sun. b. Internal Source, e.g Geothermal, i.e. Magma. 2. Man-made Heat Sources. These includes heat generated from; a. Electricity, e.g Electric Cooker and Oven. b. Fire, e.g Coal.
The main sources of heat within Earth are residual heat from its formation, radioactive decay of elements like uranium, thorium, and potassium, and heat generated by ongoing mantle convection. This internal heat contributes to processes like plate tectonics, volcanism, and the formation of geothermal energy.
An ectothermic organism relies on external sources of heat to regulate its body temperature. Examples include reptiles, amphibians, and many invertebrates.
The internal energy sources of Earth's systems include geothermal energy, radioactive decay in the Earth's core, and heat generated from the planet's formation. These energy sources drive processes like plate tectonics, volcanic activity, and the Earth's magnetic field.
external or internal sources
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
Two categories of heat sources are natural heat sources and artificial heat sources. Natural heat sources include the sun, geothermal energy, and volcanic activity. Artificial heat sources include electric heaters, gas heaters, and oil heaters.
