Geologists have divided the earth history into time units that are largely based on the earth's biotic composition. The modern geological time scale includes both relative and absolute age dating and represents the most up-to-date assessment of the earth's history.

Answer: Heat produced from the electric ice cream maker killed the grass
Explanation:
The principle behind refrigeration of the ice cream maker is that
- air from the atmosphere is collected into the condenser,
- it is mixed with refrigerant gases like liquid nitrogen
- then it becomes cool, and freezes the prepared cream to become iced
- then, the HEAT generated during this conversion is ejected from the electric ice cream maker in form of hot air.
This hot air directed towards the grass will kill its living cells, thus it turns yellow over time
