Techniques used to estimate geological time include using radioactive dating, observing rock sequences, and comparing fossils to correlate the rock sequences at various locations. Deductions can be made based on available data and observation of models as to the age of rocks/fossils.

- explain the transfer of Earth's internal heat in the mantle (crustal movement, hotspots, geysers);
- describe the interacting components (convection currents) within the Earth's system.
The outward transfer of Earth's internal heat drives convection circulation in the mantle. This causes the crustal plates to move on the face of the Earth.
