Question

The rotation and revolution speed of EARTHA globe (biggest globe in the world) is maintained as per that of the ________.
A. Sun
B. Earth
C. Moon
D. Venus

Answer 1

Hint: It has the same axial tilt as the Earth itself i.e 23.5 degrees. According to DeLorme, it’s the largest Earth image ever created.

Complete Answer:Earth’s rotation and revolution speed is maintained as per that of the Earth. It mimics the Earth’s movements and is kept inside a waterproof three-storey glass atrium at DeLorme. It is mounted on a custom designed, mechanized cantilever arm.

As the Earth is tilted at 23.5 degrees on its axis so is the Eartha. It helps Eartha mimic the real Earth’s angle.

The globe was completed on 23rd July, 1998, after two years of construction and planning. Approximately 140 gigabytes of database is used to generate the surface images.

The atrium containing Eartha is open for public viewing during business hours. There are two balconies that allow visitors to move easily so that they can see the higher parts of the globe.

The surveyors of the Guinness Book of World Records measured the globe at 41 feet and 1.5 inches (12.53 m ). The previous record holder was the Globe of Peace in Italy.

Therefore, the correct answer is option B.

Note: Rotation refers to the Earth’s spinning motion about its own axis and it results in the 24-hour day. Revolution refers to the Earth’s orbital motion around the sun and it results in the 365-day year.
