All six listed factors drive dynamic changes on Earth’s surface: solar electromagnetic radiation (weathering and climate), internal geothermal energy (volcanism), gravitational force (tides, mass wasting), plate movements (orogeny, earthquakes), Earth’s rotation (Coriolis effects, diurnal tides) and revolution (seasonal energy variation). Hence every item contributes, making option (d) correct. ([edukemy.com](https://edukemy.com/blog/upsc-prelims-2013-question-68/?utm_source=openai))
