Name: Earth Science - Note Packet #6 Mr. LaFranca s - Period Date: Aim: What are Latitude and Longitude? Do Now: Using the map, where is this location? Stamp Area X The shape of the Earth The Earth is in shape. Unlike a map which has edges, a sphere has no. It is continuous. How can you locate something on the Earth? Because the Earth is so large, imaginary lines have been made to. These smaller pieces of Earth make it easier to.
Latitude Lines Latitude lines are imaginary lines that run. They divide the Earth into Hemispheres Facts about Latitude Lines Latitude lines touch each other. They are. They are separated by increments of degrees. The is the largest Latitude. Except for the Equator, all Latitudes has an equal but. Ex- 10 o N latitude has an opposite 10 o S latitude.
Latitude
Longitude Lines Longitude lines are imaginary lines that run. They divide the earth into Hemispheres Facts about Longitude Lines Latitude lines cross each other at. They are separated by increments of degrees. There are 2 special longitudes ( ) Except for the Prime Meridian and International Date Line, all Longitudes has an equal but. Ex- 10 o E longitude has an opposite 10 o W longitude
Longitude Lines of longitude are numbered east from the Prime Meridian to the 180 line and west from the Prime Meridian to the 180 line.
Prime Meridian The Prime Meridian (0 ) and the 180 line split the earth into the. Places located of the Prime Meridian have an longitude (E) address. Places located of the Prime Meridian have a longitude (W) address. INTERNATIONAL DATE LINE 180 SEPARATES 2 CALENDAR DAYS. America to Asia Asia to America
How do Latitude and Longitude work together By combining latitude and longitude, any location can be pinpointed A location s coordinates ( N or S, E or W) Application North America is in the Hemisphere because it is north of the Equator. North America is in the Hemisphere because it is west of the Prime Meridian.
Fractions of a Degree LONGITUDE AND TIME The world rotates (spins) 360 in 24 hours. 360 / 24 hours = per hour The world has time zones, each apart. THERE IS A 1 HOUR TIME DIFFERENCE FOR EVERY 15 OF LONGITUDE Greenwich, England is the logical starting point for time zones The world rotates west to east ( ), time zones to the east are of the those time zones to the west
Questions: 1. Base your answer to the following question 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. How are latitude and longitude lines drawn on a globe of the Earth? A) Latitude lines are parallel and longitude lines meet at the poles. B) Latitude lines are parallel and longitude lines meet at the Equator. C) Longitude lines are parallel and latitude lines meet at the Equator. 2. The diagram below shows latitude measurements every 10 degrees and longitude measurements every 15 degrees. What is the latitude and longitude of point X? A) 40 S 45 E B) 50 N 45 W C) 60 S 30 W D) 75 N 30 E
3. The lines on which set of views best represent Earth s latitude system? 4. Base your answer to the following question on the information, map, and cross section below. The map represents a portion of Earth's surface in the Pacific Ocean. The positions of islands, earthquake epicenters, active volcanoes, and the Tonga Trench are shown. Lines of latitude and longitude have been included. The cross section shows earthquakes that occurred beneath line XY on the map. Depth beneath Earths surface is indicated by the scale along the left side of the cross section, as are the range of depths for shallow, intermediate, and deep earthquakes. Distance from the trench is indicated by the scale along the bottom of the cross section.
