PLEASE DRAW IT FOR ME IDK WHAT TO DO 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:

1. Research how long each eon lasted. You also might want to include the three eras of the most recent eon.
2. 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.
3. 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.

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
