✗ The International Date Line is a visible line drawn on the ocean surface.

✓ The International Date Line (IDL) is an imaginary line, mostly following the 180° meridian, where the date changes. It is not a physical line you can see.

Students might confuse it with other geographical features or imagine it as a visible line on the ground.

✗ The date changes when you cross the Prime Meridian.

✓ While the Prime Meridian (0° longitude) is the reference for time zones, the International Date Line (IDL) at approximately 180° longitude is where the date actually changes.

Both are significant longitudinal lines, leading to confusion about their distinct roles.

✗ Crossing the International Date Line always means adding a day.

✓ If you travel eastward across the IDL, you subtract a day (go back in time). If you travel westward, you add a day (go forward in time).

The concept of adding or subtracting a day can be counter-intuitive and easily mixed up, especially when considering the direction of travel.

✗ Maps are always better than globes because they show more detail.

✓ A globe is a more accurate representation of the Earth's shape and relative sizes of continents. However, maps can show much more detail for smaller areas and are easier to carry.

Students often think one is 'better' than the other without understanding their respective advantages and disadvantages.

✗ Places to the west of the Prime Meridian are ahead of Greenwich Mean Time (GMT).

✓ The sun rises in the east and sets in the west. Therefore, places to the east of the Prime Meridian are ahead of GMT, and places to the west are behind GMT.

The concept of 'ahead' and 'behind' in relation to east and west can be confusing, especially with the Earth's rotation.

✗ The Equator and the Prime Meridian are the same line.

✓ While the Equator is at 0° latitude, the Prime Meridian is at 0° longitude. They are distinct lines that intersect.

Both are 'zero' lines, leading to the misconception that they are the same or serve the same primary purpose.

✗ The Earth's rotation causes the different seasons.

✓ The Earth's rotation causes day and night and the apparent movement of the sun, leading to local time differences. The tilt of the Earth's axis (and its revolution around the sun) causes seasons.

Students often conflate the causes of day/night and seasons, attributing both to rotation.

✗ If a map scale is 1 cm = 1 km, then 2 cm on the map means 1 km in real distance.

✓ A map scale helps convert map distances to real distances. For example, if 1 cm on the map equals 1 km in reality, then 5 cm on the map equals 5 km in reality.

Students may understand the concept of scale but struggle with the actual calculation or misinterpret the ratio.
