Navigation Activity 2
1. What were three methods of determining latitude and which one was the most accurate?
a. Astrolabe
b. Cross-staff
c. Back-staff – most effective
2. Which was more difficult to determine, latitude or longitude? Explain.
Longitude was harder to determine because the concept of time was always against them. And the sun was always moving so it made it harder to grasp the length of space between 2 locations.
3. What two devices helped navigation become more accurate? Explain.
Sextant and Chronometer
4. Which way do lines of latitude run and what do they measure?
They run from east to west and measure the distance north and south of the equator.
5. Which way do meridians run and what do they measure?
Lines of longitude, called meridians, run in a north-south direction from pole to pole and measure degrees◦
6. How far is it from your home town to Sarasota, Florida, our point of origin for our journey?
It is 2 hours and 55 minutes
164 miles (264 km) (143 nautical miles)
Initial heading from Pembroke Pines to Sarasota: northwest (304.3 degrees)
Initial heading from Sarasota to Pembroke Pines: east-southeast (123.3 degrees)
14001 NW 4th St. apt 102 Pembroke Pines FL, 33028 to Sarasota FL
7. What is the exact location of your town using latitude and longitude?
26:00:35N 80:20:26W
8. List two real life situations in which an exact position, determined down to the seconds of latitude and longitude, would be important.
