Let's solve the problem step by step using the map provided in the worksheet.
The map shows the United States with lines of latitude (horizontal lines) and longitude (vertical lines). The task is to identify the state located at each given latitude and longitude coordinate.
Step 1: Understand the Coordinates
-
Latitude measures how far north or south a location is from the equator. It ranges from 0° at the equator to 90°N at the North Pole.
-
Longitude measures how far east or west a location is from the Prime Meridian. It ranges from 0° at the Prime Meridian to 180°E or 180°W.
On this map:
- Latitude lines are labeled: 30°N, 40°N, 50°N
- Longitude lines are labeled: 70°W, 80°W, 90°W, 100°W, 110°W, 120°W
We’ll use these grid lines to find the states.

Step 2: Solve Each Question
#### 1.
30°N latitude, 100°W longitude
- Find the intersection of 30°N and 100°W.
- This point is in
Texas.
✔ Answer: Texas
#### 2.
45°N latitude, 110°W longitude
- 45°N is just below the 50°N line (about halfway between 40°N and 50°N).
- 110°W is near the western edge of the U.S.
- This location is in
Montana.
✔ Answer: Montana
#### 3.
40°N latitude, 90°W longitude
- 40°N is the horizontal line passing through the middle of the U.S.
- 90°W runs through the central part of the country.
- This point is in
Illinois.
✔ Answer: Illinois
#### 4.
40°N latitude, 120°W longitude
- 40°N again.
- 120°W is on the far western side of the U.S., near California and Nevada.
- At this intersection, we're in
California (the northern part).
✔ Answer: California
#### 5.
30°N latitude, 95°W longitude
- 30°N is near the southern border of the U.S.
- 95°W is slightly west of 90°W.
- This location is in
Texas (southern part).
✔ Answer: Texas
#### 6.
40°N latitude, 80°W longitude
- 40°N is the same as before.
- 80°W is near the eastern U.S., passing through Ohio, Indiana, etc.
- This point is in
Ohio.
✔ Answer: Ohio

Summary:
Using the map’s grid of latitude and longitude, we identified the states by locating where each pair of coordinates intersects. Always follow the horizontal (latitude) and vertical (longitude) lines to pinpoint the correct state.
