Answer:
The incorrect statement is - Energy is created and destroyed when it changes forms.
Explanation:
The conduction or transfer of energy required close contact between particles of the molecules therefore conduction does not take place in gases as they are not in direct contact with their molecules. Radiation involves waves that may generate due to the electromagnetic field.
Convection describes the transfer of energy by movement of dense fluid or fuel to warm the colder are it explains how a heater warms up the inside of a car. The third option is incorrect as energy can not be formed or destroyed in any circumstances or system it will just change it form.
<span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them.
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
Sorry its so long but that the answer i think >:) ur welcome
