Knowing our world is a necessity for everyone, whether you care for such knowledge or not. The parts of the world we live notwithstanding, the basic knowledge of time, space, distance, location, land formations and other information of geography must be in our cognitive kitty. And as we progress in our living, we can bear along these variables as it affects what we do and how we do them.

This is because as we continue with life, lots of natural happenings beset us daily and some of those happenings are far beyond our comfortable understanding and we find it difficult to adjust and at times, filled with fear of the unknown. This is why we are encouraged to help ourselves with how our world operates.

 

Earthquakes

Those in Africa and other regions not prone to earthquakes may not fully understand the predicaments of residents in Mexico, Japan, India, El Salvador, Indonesia, Pakistan, Nepal, Turkey, Philippines etc. These people have accepted their fate. Has anyone here experienced earth tremor, let alone quakes, volcanic eruptions etc? Recent earthquakes offshore Guatemala, Ryukyu Island Japan, Central Peru, Nepal etc, left behind bad tales for the inhabitants to tell. Not many, not most of us have had such experience. Yet we empathize with those concerned by means of reports, photographs, video shots reaching us wherever we live on the globe, which are enough prove of what transpired.

Earthquakes are common phenomenon in areas as mentioned above owing to their locations around fault lines underneath the earth layer. These faults tends to widens in response to constant earth movements, causing vibrations. Such information at the reach of relevant seismological agencies enables timely warning such as to make way for evacuation of residents in the epicenter (the place at which the vibration spreads out to many kilometers away) for safety.

 

 

Time Calculation

As we engage in intercontinental journeys also, we observe change in time. A traveler would have to change his or her time to depict that of host country on arrival. The working is simple: one can calculate by self the time with the knowledge of longitude. The Greenwich Meridian is zero, meaning that the longitude starts from there and count 180 degrees westward and eastward.

Knowing your time works on the principle of 40 = 1mins; 150= 1hr. For every 40 journey made on the earth’s surface westward, 1minute is lost; while going same journey eastward attracts a gain of that time margin. Same applies to the 150. So countries like UK and Ghana, which lie on the Greenwich Meridian (00) share same time but Nigeria differs by an hour gain because it is located on 150 longitude eastward of the Greenwich Meridian. This is why Nigeria is an hour ahead of the local time in UK and Ghana in real life setting. The metric applies to all countries on the earth’s surface depending on their longitude. Now you know.

 

Distance

Latitudes are the imaginary horizontal lines drawn across the globe to calculate distance of places on earth surface. The most important of them is the equator which divides the earth into equal halves and it is zero degree.

The interaction of both longitude and latitude makes the location of certain place possible. This can be verified on a simple globe found in a laboratory, office, school etc.

 

Pressure

Knowing your world is an adventure that should be encouraged indeed. Has it every crossed your minds (for those who have boarded aircrafts or those in a submarine) the reason cabin crew and passengers experience a low pressure and the occupants of the submarine experience the opposite- high pressure? This is simply because pressure reduces with an increase in height while it increases proportionately with depth.

We would continue from here some other time but until then, keep living in the knowledge of your world.
