You are going to design a clock to represent the different geologic eons throughout Earth's history. Here are the steps you need to take to complete your geologic time scale clock: Research how long each eon lasted. You also might want to include the three eras of the most recent eon.
Knowing that each hour of the clock is about 375 million years, determine how many hours each eon takes up on our 12-hour clock. For example, if an eon took 750 million years, that would take up two hours of the clock.
Within each eon, identify major events and the types of life that dominated the earth during that time.
How you design your clock is up to you. You can use a computer program to design your Clock of Eons or you can go old school and use poster board and markers. Let your imagination soar and create a Clock of Eons that will surely impress! Upload your clock in the box below.

here you go hope it heps "horace mann"

the correct answer for the first is d

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.

the answer is true sir
