RELATIVE DATING is a way to estimate the order of geologic events by using rock layers, index fossils or other methods.
Relative dating is used by geologists to arrange geological events in sequential order. Relative dating usually use six principles to determine the relative age of any rock or fossil. The principles are: principle of superposition, principle of original horizontality, principle of lateral continuity, principle of cross cutting, principle of inclusions and principle of fossils succession.
Answer:
Answer is a natural process.
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.
