Final answer:
Heat energy on Earth is mainly distributed through convection, as seen in the movement of ocean currents, and by radiation and conduction. The correct answer is B) By the movement of ocean currents.
Step-by-step explanation:
Heat energy is distributed and cycled through Earth's spheres by several processes, which can be observed in our environment. The energy from the Sun, which is generated by nuclear fusion, reaches Earth in the form of radiation, including ultraviolet, visible light, and infrared rays. This energy is then absorbed by Earth's surface and re-radiated back into space as heat. One of the key mechanisms by which this heat is moved around within Earth's systems is through convection, where warm material rises and cooler material sinks, creating currents. This can be seen, for example, in the movement of ocean currents which distribute heat around the globe and in the magma convection beneath the Earth's crust.
The correct answer to the question 'How does heat energy get distributed and cycled through Earth’s spheres?' is B) By the movement of ocean currents and additionally by other mechanisms such as radiation, conduction, and convection. Conduction involves the transfer of heat through direct contact, while radiation is the emission of energy as electromagnetic waves. Together, these processes facilitate the movement of heat and support Earth's climate system and life.
