1 Name: Earth Science - Note Packet #7 Mr. LaFranca s - Period Aim: What are time zones and why are they important? Date: Stamp Area Do Now: Why do you think East Coast football games start at 1:00 and West Coast games start at 4:00? The shape of the Earth The Earth is shaped like a ball or a. To go completely around the Earth,. The Sun only shines on. But because the Earth spins or or West to East direction, sunlight will touch all of the. The position of the Sun and is different. Example: In the morning, the Sun is rising in Brooklyn, but setting in Tokyo, Japan. Time Zones Time on Earth is. Longitudes divide the Earth into 24 sections called. Each Time Zone equals a. 15 o x 24 = 360 o

2 Facts about Time Zones There are 24. Time Zones, which crosses through the city of Greenwich, England. Because Time Zones cross each other at the, the distance between them varies depending. Time Zones are not always (north and South). Sometime the Time Zone is in the same Time Zone. The divides the days of time. Example Monday and Tuesday.

3 Time Zones in the United States The US has 6 time zones 4 on the US mainland 1 for Alaska 1 For You can calculate the time of any city if you know How do we use Time Zones you cross to get to the city you wish to know the time. Example 1: It is 8:00 a.m. in Brooklyn, what time is it in Paris. Going East. Going West

4 Times of other Cities in Respect to your City. Depending of the location of other cities when compared to your location,. If the city is located East of your city and in a different time zone,. Example NYC is 12 p.m. and Rome is 6 p.m. If the city is located West of your city and in a different time zone,. Example NYC is 12 p.m. and LA is 8 a.m. If the city is located North or South of your city and is in the same time zone,. Example NYC is 12 p.m. and Boston is 12 p.m. and Miami is 12 p.m.

5 Questions: 1. Base your answer to the following question on Letters A, B, C, D, and X on the map below represent locations on Earth. The map shows the latitude-longitude grid. Solar time is based on the position of the Sun. If the solar time is 1 p.m. at location X, at which location is the solar time 5 p.m.? A) A B) B C) C D) D

6 2. Base your answer to the following question on the United States time zone map shown below. The dashed lines represent meridians (lines of longitude). The basis for the time difference between adjoining time zones is Earth's A) 1 per hour rate of revolution B) 1 per hour rate of rotation C) 15 per hour rate of revolution D) 15 per hour rate of rotation

7 3. Base your answer to the following question on passage and time zones map shown below. Time Zones In 1883, Earth was divided into 24 time zones. The United States (excluding Alaska and Hawaii) has four time zones, which are indicated by different shadings on the map. Each zone is roughly centered on lines of longitude that are 15 apart. These lines are shown as dashed lines on the map. Most locations within a time zone have the same time. This time is called standard time. As you move to the west, the time in each zone is one hour earlier than the previous time zone. When it is 1 a.m. in New York City, what time is it in Denver? A) 11 p.m. B) 11 a.m. C) 2 p.m. D) 2 a.m.

8 4. Base your answer to the following question on the map below. Letters A through F are locations on Earth s surface. When solar time at location E is 12 noon, solar time at location A is closest to A) 6 a.m. B) 8 a.m. C) 12 noon D) 4 p.m. 5. Base your answer to the following question on the map below which represents a view of the Earth looking down from above the North Pole (N.P.), showing the Earth's 24 standard time zones. The Sun's rays are striking the Earth from the right. Points A, B, C, and D are locations on the Earth's surface. Areas within a time zone generally keep the same standard clock time. In degrees of longitude, approximately how wide is one standard time zone? A) 7 º B) 15º C) 23 º D) 30º

9 Base your answers to questions 6 through 8 on the latitude and longitude system shown below. The map represents a part of the Earth's surface and its latitude-longitude coordinates. Points A through F represent locations in this area. 6. In respect to location A, which location has a clock that reads later in the day? A) B B) D C) C D) F 7. In respect to location D, which location has a clock that reads earlier in the day? A) B B) D C) C D) F 8. In respect to location A, which location has a clock that reads the same time of the day as location A? A) B B) D C) C D) F
