Southern Hemisphere
Definition
The Southern Hemisphere is the half of the Earth that is south of the equator. The equator is an imaginary line that divides the Earth into two equal halves, the Northern Hemisphere and the Southern Hemisphere.
The Southern Hemisphere includes the following continents:
- Antarctica
- South America
- Africa
- Australia
- New Zealand
The Southern Hemisphere also includes the following islands:
- Madagascar
- New Caledonia
- Fiji
- Tonga
- Samoa
The Southern Hemisphere has different seasons than the Northern Hemisphere. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. This is because the Earth is tilted on its axis, and the Southern Hemisphere gets less sunlight in the winter.
The Southern Hemisphere also has different weather patterns than the Northern Hemisphere. The Southern Hemisphere is generally warmer than the Northern Hemisphere, and it has more rain. This is because the Southern Hemisphere is closer to the equator, and the equator receives more sunlight than the rest of the Earth.
How can the word be used?
The Southern Hemisphere has a warmer climate than the Northern Hemisphere.
Different forms of the word
Noun: The half of the Earth that is south of the equator.
Adjective: Relating to or located in the Southern Hemisphere.
Etymology
The etymology of the word "Southern Hemisphere" can be traced back to the Latin word "hemisphaerium", which means "half of a sphere". This word is made up of the prefix "hemi-", which means "half", and the noun "sphaera", which means "sphere".
The word "Southern Hemisphere" first appeared in English in the 16th century. It was originally used to refer to the half of the Earth that was south of the Tropic of Capricorn. However, the definition of the Southern Hemisphere has since been expanded to include all of the Earth that is south of the equator.

AQA Science Exam Question and Answer
Question:
Describe the unique features of the Southern Hemisphere's night sky, including prominent constellations and celestial phenomena, and explain how these differ from those observed in the Northern Hemisphere.
Answer:
The night sky in the Southern Hemisphere offers a different celestial panorama compared to the Northern Hemisphere. One of the most noticeable distinctions is the presence of the Southern Cross (Crux), a well-known constellation not visible from most Northern Hemisphere locations. The Southern Cross serves as a prominent navigational and cultural marker in the southern skies.
Another remarkable sight is the Magellanic Clouds, two satellite galaxies of our Milky Way, which are easily seen from Southern Hemisphere latitudes. These irregular galaxies are not visible in the Northern Hemisphere due to their southern location.
Additionally, the Large and Small Magellanic Clouds offer breathtaking views of nebulae, star clusters, and other celestial objects that are unique to the Southern Hemisphere. The Southern Hemisphere also provides optimal views of the centre of the Milky Way, where a concentration of stars, gas, and dust creates a striking and rich tapestry of cosmic wonders.
Observing the night sky from the Southern Hemisphere provides a fresh perspective on the cosmos, offering access to constellations and celestial phenomena that are inaccessible to observers in the Northern Hemisphere. The contrasting views between the two hemispheres enrich our understanding of the universe and contribute to the fascination of astronomy.
