- The earth is divided into the Northern and the Southern Hemispheres by the equator.
- The word hemi/sphere in Greek means, literally, ‘half ball’.
- The Northern Hemisphere is the northern half of the Earth. It begins at 0° or the equator and continues north until it reaches 90°N latitude or the North Pole.
- The Southern Hemisphere is the southern portion or half of the Earth (map). It begins at the equator at 0° and continues south into higher latitudes until it reaches 90°S or the South Pole in the middle of Antarctica.
- The Northern Hemisphere has almost 90% of the planet’s land and the Southern Hemisphere has 90% water. So most of the world population lives in the Northern Hemisphere.
- The continents making up the Southern Hemisphere include all of Antarctica, around 1/3 of Africa, most of South America and nearly all of Australia.
- All of Europe, North America, Central America and the Caribbean plus the vast majority of Asia, about two-thirds of Africa, and a tenth of South America are in the Northern Hemisphere.
- All of the Arctic Ocean is in the Northern Hemisphere as well as the northern parts of the Pacific, Atlantic and Indian Oceans as well as many seas.
- Four oceans: South Atlantic, Indian Ocean, South Pacific, and most of Oceania are in the Southern Hemisphere.
- There are far fewer and less bright visible stars in the northern hemisphere compared to the Southern Hemisphere, making the Northern Hemisphere more suitable for deep-space observation, as it is not 'blinded' by the Milky Way.
- However, the earth’s tilt combined with clearer skies, makes for excellent viewing of the night sky from the Southern Hemisphere with brighter and more numerous stars.
- Climates in the Southern Hemisphere tend to be slightly milder overall than those in the Northern Hemisphere at similar latitudes except in the Antarctic which is colder than the Arctic.
- Because of the large presence of water in the Southern Hemisphere, climate in the Earth's southern half is milder overall than the Northern Hemisphere. In general, water heats and cools more slowly than land so water near any land area usually has a moderating effect on the land's climate. Since water surrounds land in much of the Southern Hemisphere, more of it is moderated than in the Northern Hemisphere.
- The Arctic is the area that is north of the Arctic Circle at 66.5°N. It has a climate with very cold winters and cool summers. In the winter, it is in complete darkness for 24 hours per day and in the summer it receives 24 hours of sunlight.
- Antarctica is the largest landmass in the Southern Hemisphere and it is the world's largest cold desert. Although it is the largest area of land in the Southern Hemisphere, it is not populated because of its extremely harsh climate and the difficulty of building permanent settlements there. Any human development that has taken place in Antarctica consists of scientific research stations- most of which are operated only during the summer.
- The Southern Hemisphere is significantly less polluted than the Northern Hemisphere because of lower overall population densities, lower levels of industrialisation, and smaller land masses.
- The majority of the Northern Hemisphere's population speaks one of just five languages: Portuguese, English, Spanish, French, or Indonesian, while there are countless languages in the Southern Hemisphere.
- When it is summer in the Northern Hemisphere, it is winter-time in Southern Hemisphere.
- The days & nights are of same length all year around on the equator. But days get shorter on poles during winter and longer during summer.
- The moon seems to be upside down in the Southern Hemisphere.
- Shadows move clockwise in north and anti-clockwise in south.

FUN FACTS ABOUT EARTH’S SOUTHERN AND NORTHERN HEMISPHERES

FASHION FADES, STYLE IS ETERNAL
When legendary designers such as Coco
Chanel said this, they were not joking. The world of fashion is ever changing
and trends come and go quickly. One moment it’s all about rocking the neons and
pastels and the next everyone is crazy about metallics and all that shimmers.
Some of you might still be wondering where exactly I’m heading to so let me
bring you out of the dark. True African Women, the most important thing ever is
to ALWAYS stay true to yourself, your roots, and, your STYLE!
In this day and age, a lot of us are,
to put in simple terms, FASHION SLAVES. We seem to wear whatever is trending
just for the sake of it being a fashion trend of the moment. Or, even worse, we
think that just because Solange or Oge Okoye look nice in something, we also
can automatically look equally fabulous in it be it fiery red box braids or a
bustier. It is important to note that celebrities should be your STYLE not FASHION icons. By that, ladies, I mean you should watch the way a
celebrity whose style matches yours dresses. For example, if you have a
versatile and elegant style like that of Genevieve Nnaji, then try emulating
her fashion choices, it is that simple.
As I’ve mentioned before, trends come
and go in a flash. No matter how many people are following the trend or how
gorgeous whatever is trending is, do not succumb to pressure. You should
only invest in trends that suit your style, your pocket and the life you lead.
Following a trend that will cost you a fortune or is not for your body shape
will leave you broke AND you will be a serious fashion disaster which you will
regret.
A very good example is the time when
Rihanna decided to dye her hair a sexy, fiery RED for her album, LOUD. This
made a lot of us feel like we could also rock an entirely RED hairdo. Some
looked A-M-A-Z-I-N-G while with some, it was actually scary. This is mostly for
that daring diva who not only has the LOUD personality, but the perfect skin
tone too.
Riri rocked it - could you?
YOUR HEALTH DURING PREGNANCY
Getting pregnant in the right context is always an
exciting experience; the right context being when you are ready emotionally,
physically, financially and socially. By this time the thought of bringing on
Earth a new life is both amazing and scary because this is not just playing
house anymore, it is the real thing. So this week we thought we would give our
fellow True African Women all over the world a few tips on how to keep healthy
before and during pregnancy so as to ensure that your baby is as healthy as
healthy gets.
BEFORE THE PREGNANCY
In
many cases, people do not usually plan to get pregnant, especially if is the
first time. People usually get caught up in the excitement of the moment and
before they know it, they are moms to be. If they are fortunate, the guy
responsible takes responsibility, but in most cases, this is how single
parenthood happens.
In
a perfect world, raising a child would be as easy as 1 2 3, but the world is
not perfect, hence there is nothing easy about raising a child. They can be
little angels, but on many occasions, they are little terrors. So to make sure
you do not end up at the psych ward, you need to make sure you are ready to
have a child, and plan for one.
One
year before, get a physical exam. Talk with your regular doctor to find out how
your health may affect your ability to conceive and carry a baby to term. Make
sure that, in your physical exam, you address your blood pressure readings and
your blood sugar levels.
Healthy
pregnancy begins before you become pregnant. It actually begins long before you
even think about motherhood. Take a moment to learn what you can do now to make
sure any future pregnancies are planned and healthy.
DURING THE PREGNANCY
It
is always important to be actively concerned about your health, but even more
so when you are pregnant. It is imperative because your baby depends on you to
create the best environment for its every development. Therefore, you should:
·
Eat well-balanced meals each
day.
·
Drink plenty of fluids -- at
least eight to 10 glasses a day -- avoiding caffeine and artificial colouring.
·
Not drink alcohol.
·
Not smoke or allow yourself to
be exposed to second-hand smoke.
·
Exercise – Exercise can ease
and prevent aches and pains of pregnancy including constipation,
varicose veins, backaches, and exhaustion.
Active women seem to be better
prepared for labour and delivery and recover more
quickly.
·
Get adequate sleep -- at least eight
hours a night. If you're suffering from sleep disturbances, take naps during
the day and see your physician for advice.
·
Wear comfortable, non-restricting shoes
and put your feet up several times a day to prevent fatigue and swelling of the
feet, legs, and ankles.
·
Not take over-the-counter medications or
herbal remedies without first consulting your obstetrician or midwife.
·
Not
partake in anything that can raise your body temperature too high (hot tubs,
saunas or steam rooms). These have been implicated as possibly increasing the
risk for birth defects.
·
Avoid
exposure to Pesticides,
insecticides, herbicides, fungicides and other toxic chemicals. These can harm
the unborn baby to various extents depending on the toxicity and duration of
exposure. They can also cause delays in development especially if the foetus is
exposed to them in the first trimester.
·
It is also advisable for pregnant women
to avoid exposure to x-rays and other types of radiation. Although the risk is
not much x-rays can be more harmful during early pregnancy. Therefore inform
your doctor or dentist about your pregnancy so that x-ray can be postponed if
possible. Studies have shown that even low levels of exposure to strong electromagnetic
fields can cause some cell damage. Therefore pregnant women must avoid electric
blankets as well as standing too close to the TV or in front of the microwave
for long durations.
After all has been said and done, it
is important for you to have a good relationship with your obstetrician and
ensure that you ask for his/her advice on everything you do during this period.
AFRICAN FOLKTALES
Since
ancient times, storytelling in the African culture has been a way of passing on
traditions, codes of behaviour, as well as maintaining social order. The
African storyteller was a poet, singer, historian, musician, comedian, an
entertainer, an archive and so much more. It was through him that knowledge,
history, and experiences were able to be passed from one generation to the
next.
What is storytelling? One
might ask. How is it different from reading a story or reciting a piece from memory?
Storytellers in Africa were performers who entertained, inspired, and educated
their audiences. They knew how to captivate the audience with more than just
words. The storytellers would use gestures, singing, facial expressions, and
impersonations to arouse the audience. When a story was told, the audience would
participate in accounts of past deeds, beliefs, taboos, and myths.
Animals, mainly in the form of tricksters, play a
prominent role in African storytelling because African people live in close
proximity to wild animals that share their land.
The animal tricksters differ from culture to culture. The hare is the most
prominent trickster among the people of East, Central, and Southern Africa. The
tortoise is the trickster hero in many parts of Nigeria. The spider is the
animal trickster in Liberia, Sierra Leone, and the Gold Coast. Each culture has
its own unique way of describing and utilizing its trickster. Animal tricksters
have exceptional qualities, mental agility, and extraordinary capabilities.
They are portrayed as lazy, greedy, talented, clever, and mischievous. They
deceive friends, acquaintances, and adversaries in pursuing their own selfish
ends. The storyteller’s audience appreciates the wit that leads the animal
trickster from one victory to another.
In many of the tales Africans attributed human
feelings and desires to particular animals and derived ethical ideas from their
behaviour. A common African trickster tale is about Pride Coming before a Great Fall. The
deer bragged about running faster than any animal at the meeting of all
animals. According to the deer, he could run over twenty-six miles. Although
the tortoise accepted the challenge, he arranged for thirteen of his family
members to be stationed at every other mile. At the beginning of the race the
deer teased the tortoise because he was behind him. As each of tortoises family
members shouted ahead of the deer, he ran more rapidly. The deer died of
exhaustion two miles before the end of the race. The folktale teaches that too
much arrogance has severe consequences.
In the ancient times, storytelling was one of
the most valued forms of entertainment. Often, people were told the stories by
the light of the moon around a village fire after the completion of a long day
of hard work at the fields. Without the modern day televisions, radios and
social networks to make use of for leisure, storytelling provided the perfect
release.
