Eon - Half a billion years or more Epoch - Tens of millions of years Era - Several hundreds millions of years Age - Millions of years 11) List three ancient calendars Egyptian Calendar, Aztec and Stonehenge 12) List two ancient clocks and how they worked. Sun clocks - Their moving shadows formed a type of sundial, giving people the ability to partition the day into morning and afternoon. Water clocks - Markings on the inside surfaces measured the passage of "hours" as the water level rose to meet them. These clocks were used to determine hours at night, but could have been used in the daylight as well. 13) What was a revolution of timekeeping? Accurate Mechanical Clocks to Quartz clocks. 14) What allows for standard more accurate clocks? There are no gears or escapements to disturb their regular frequency. 15) What are time zones? A region on earth that has a uniform standard time for commercial, legal and social purposes 16) What is the prime meridian? The vertical line that marks the zero degree longitude measurement on the globe of the Earth. The line intersects the the latitude lines that are horizontal. 17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii? Toronto - 11:00am London - 4:00am Moscow - 8:00pm Tokyo - 1:00am Hawaii - 6:ooam 18) What is Daylight Saving Time? Do we use this in Saskatchewan? During late winter we move our clocks one hour ahead and "lose" an hour during the night, in fall we move our clocks back one hour and "gain" the hour back. We don't use it in Saskatchewan. 19) Is there a year zero? No 20) Are we starting a new decade in 2010 or 2011? 2011 21) What is linear time? Linear time is a major feature of our Western cultural world view, initiated by Newton some 300 years ago. It portrays time as an absolute physical reality, and says that the passage of time is independent of consciousness, which means that it doesn't matter what you think, feel or do or how you look at time, it will always stay the same. 22) What is cyclical time? Time that is based from moving cycles

Geological Time Playlist We learned: - Earth is divided into four geologic eras; Precambrian, Paleozoic, Cenozoic, Mesozoic - Precambrian is the oldest division of time - Paleozoic is the era of geologic time charcterized by the appearance of primitive fishes, land plants and primitive reptiles - Mesozoic - relating to the third era of geologic time - Cenozoic - relating to the latest area of time - Mammals survived during Cenozoic area - Plate tectonics is the puzzle of continents - Pangea was the super continent, meaning all lands - Alfred Wegener came up with the theory of Plate Tectonics (Continental Drift Theory) in 1911 - Mid-ocean ridges are underwater mountain systems

How were the creatures and plants on earth formed? Why are the eras named after Greek words? Why do plate tectonics move?

I think the point of watching these videos is because you don't do it often so it might stick in your head better, also just to learn new information that you might not have known.

48/48 great work
