Explanation:
Enlist three reasons as to why the invention of wheel was an important achievement of humankind.
ANSWER?
One of the reasons why the wheel was invented only at this point in history is due to the fact that metal tools were needed to chisel fine-fitted holes and axles. This leads to the next reason – the wheel was not just a cylinder rolling on its edge. It was a cylinder that was connected to a stable, stationary platform.
) What are the main reasons for the decline of Harappan Civilisation?
People believe the main cause of the sudden decline is climate change. Huge climate change or natural calamities might have been a cause of the ruin of Harappan civilization. It has been found that some climate change happened around 2000 BC.
There is an imaginary line in the middle of the Pacific Ocean. It runs from the North Pole to the South
Pole and is almost directly on the opposite side of the Earth from the Prime Meridian. Can you identify
that imaginary line? Why we need that line in the middle of the Pacific Ocean?
An imaginary line running from North to South through the center of the Earth is the Prime Meridian or the Green Witch Meridian.
A prime meridian is a meridian in a geographic coordinate system at which longitude is a defined to be 0° and passing through the center of the Earth.
