Compass Directions navigational instrument that shows _________in a frame of reference directions on the Earth “Never Eat Soggy Wheat”

Latitude - or FLATitude - EAST/WEST Reference line: ______________ The Equator NORTH/SOUTH Measure __________________ Lines that run _______________ of equator How to remember: ladder

Latitude How far North or South something is from the equator! (90°N) Increasing from 0° at equator to 90°N at NP Northern Hemisphere Increasing from 0° at equator to 90°S at SP Southern Hemisphere (90°S)

Any location north of the equator is a NORTH LATITUDE

Any location south of the equator is a SOUTH LATITUDE

How can we measure latitude without a GPS? POLARIS!!!

Polaris star located directly above the POLARIS: a _____________________ (also called the North Pole “North Star”) Angle from the horizon to Polaris gives an observer their ___________ latitude Only works in the Northern Hemisphere. . . WHY

Polaris Zenith

Polaris

What would be this observers latitude?

What would be this observers latitude?

At what altitude would we see Polaris in the Night Sky here in Greenville, NY?

Longitude NORTH/SOUTH Prime Meridian (0°) – Reference line: ______________ Lines that run ______________ passes through Greenwich, England EAST/WEST Measure ______________ of Prime Meridian Meet at the POLES! Way to remember: Orange

The Royal Observatory, Greenwich, England

Longitude Lines of longitude go up to 180° east or south of Prime Meridian and meet at the International Date Line _______________________

Any location west of the prime meridian is a WEST LONGITUDE

Any location east of the prime meridian is an EAST LONGITUDE

How can we measure Longitude without a GPS?

Longitude without a GPS noon (12 pm) Sun at highest point at ____________ 24 It takes ____ hours for the Earth to rotate 360° 15°per hour Sun moves across the sky at ___________ So longitude can be measured simply with a clock!

Orange cut through lines of longitude Orange cut through lines of latitude

Is it possible to walk around the globe crossing all 360° of longitude in a minute? If so, where? Is it possible to walk across all lines of latitude in a minute? If so, where?

By combining latitude and longitude, any point can be pinpointed

Why do we need a grid system?

A location’s coordinates: _______ °N or °S, _______ °E or °W Example: Detroit 42°N 83°W

What are the coordinates of location A? What are the coordinates of location B? What are the coordinates of location C? 0° W 15° W 30° W 45° W 60° W 75° W 90° W 105° W 75° N B 60° N 45° N 30° N 15° N A C 0°
