What imaginary lines are boundaries of the Eastern Hemisphere?

Prime Meridian at 0 degrees and Prime meridian at 180 degrees?

Your latitudes are correct, but we only call 0 degrees the Prime Meridian.

What is the capital of the country that separates the North Sea from the Baltic Sea?

Is the country Denmark and the capital Copenhagen?

Oh so for the one above it is just 180 degrees longitude? and the prime meridian

Thank you!

Yes, you're right.

Yes, you're correct! The Prime Meridian at 0 degrees and the Prime Meridian at 180 degrees are the two boundary lines that define the Eastern Hemisphere.

To understand this concept, it's helpful to know that the Earth is divided into four hemispheres: Northern Hemisphere, Southern Hemisphere, Western Hemisphere, and Eastern Hemisphere. The Prime Meridian plays a crucial role in determining the division between the Eastern and Western Hemispheres.

The Prime Meridian, located at 0 degrees longitude, passes through the Royal Observatory in Greenwich, London. It is used as the reference point to measure all other longitudes. As you move eastward from the Prime Meridian, you enter the Eastern Hemisphere. Conversely, as you move west from the Prime Meridian, you enter the Western Hemisphere.

However, to fully enclose the Eastern Hemisphere, another boundary line is needed. This is where the Prime Meridian at 180 degrees longitude comes into play. It is exactly opposite the Prime Meridian at 0 degrees and is also known as the International Date Line. When you cross the International Date Line from east to west, you transition from the Eastern Hemisphere to the Western Hemisphere, completing a full circle around the Earth.

So, to summarize, the boundaries of the Eastern Hemisphere are the Prime Meridian at 0 degrees and the Prime Meridian at 180 degrees (International Date Line).
