The meridian of 45 degrees east passes through what four continents

Europe, Asia, Africa, Antarctica

To determine which four continents the meridian of 45 degrees east passes through, you can refer to a map or globe.

Here are the steps to find the answer:

1. Start by identifying the 45 degrees east longitude line on a map or globe.
2. Follow the longitude line from the North Pole to the South Pole, crossing various territories.
3. As you trace the line, observe which continents it passes through.

Based on the above procedure, the meridian of 45 degrees east passes through the following four continents:

1. Europe: The countries it crosses in Europe include Norway, Sweden, Finland, Estonia, Russia, Belarus, Ukraine, and Greece.
2. Asia: It then continues to run through Russia, Kazakhstan, China, and Indochina.
3. Africa: The line passes through Sudan, South Sudan, Democratic Republic of the Congo, and Angola.
4. Antarctica: Finally, the meridian intersects with the continent of Antarctica.

Remember, longitude lines are vertical lines that run from the North Pole to the South Pole, whereas latitude lines are horizontal lines that run parallel to the equator.
