What information does the geologic time scale provide? SELECT THREE options.

list of rock layers by age

end date of a geological period

places where dinosaurs roamed on Earth

reasons why organisms evolve into different species

information about when plants first appeared

Explanation:

The geological time scale gives us the following information:

-List of rock layers by age.

-end date of geological period.

-information about when plants first appeared.

A chronology of time periods which reflects  the relationship between geological strata and time. It gives information of various events that took place during the evolution of life on earth. It also gives us an idea about the age of rock. The geological time scale is divided into Eon , era , period and epoch.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
