Which theory describes the collective effects of changes in Earth's movements on its climate over thousands of years?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Milankovitch theory.
The Milankovitch theory outlines how changes in Earth's movements affect its climate over extended periods. Developed by Serbian mathematician Milutin Milankovitch, the theory highlights the role of variations in Earth's orbital shape, tilt, and axial precession in determining how solar energy is distributed across the planet. These astronomical changes influence climate trends and are associated with the onset of glacial and interglacial phases. By studying these cycles, scientists gain insights into past climate variations, which aids in enhancing our understanding of contemporary climate models and their implications for the environment.
