Grade 5 students discover the International Date Line at 180 degrees longitude and learn how it connects to Earth's 24 time zones in this engaging social studies worksheet. Through sentence correction, fill-in, and short answer practice, Grade 5 learners explore how each time zone spans 15 degrees of longitude, why the Date Line crosses the Pacific Ocean, and how crossing it changes the calendar day during travel.

Latitude and Longitude
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The International Date Line follows the meridian at zero degrees longitude across the Pacific.
Rewrite: The International Date Line follows the meridian at 180 degrees longitude across the Pacific.
2. Fix the sentence:
Earth has 12 standard time zones, each spanning 30 degrees of longitude on the globe.
Rewrite: Earth has 24 standard time zones, each spanning 15 degrees of longitude on the globe.
3. Fix the sentence:
When you cross the Date Line traveling west, you subtract one day from the calendar.
Rewrite: When you cross the Date Line traveling west, you add one day to the calendar.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The International Date Line runs near the 180-degree meridian through the Pacific Ocean.
2. Each standard time zone covers 15 degrees of longitude around our spinning planet.
3. The Prime Meridian at 0 degrees longitude passes through Greenwich, England, near London.
4. Crossing the Date Line going east means you go back one calendar day on your trip.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why was the International Date Line placed at 180 degrees longitude in the Pacific Ocean?
It was placed there because 180 degrees is opposite the Prime Meridian and runs mostly through open ocean, avoiding confusion in populated land areas.
2. How does longitude help create time zones for navigation and daily life on Earth?
Longitude divides Earth into 24 sections of 15 degrees each, with each section representing one hour, allowing places to set local time based on the sun's position.
