- Oceanic plates are relatively very young as they are formed at spreading centers and destroyed at convergent margins.
- Continental masses have very high absolute ages.
- The oldest rock on earth such as the Kabala Gneiss have been dated to be about 3 billion years.
- Other rocks have yielded ages close to the formation of the earth.
- We can conclude that the continents began to form immediately after the earth was formed.

Earth's rotation causes day time and night time. When the earth is tilted towards the sun, the area tilted towards the sun receives more radiation, and is probably in summer/spring. When the earth is tiled away from the sun, the area tilted away receives less sunlight, so it is probably in fall/winter.
