Earth's Rotation Quiz

______ rotates eastward, in prograde motion. As viewed from the northern polar star Polaris, ______ turns counterclockwise. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where ______'s axis of rotation meets its surface. This point is distinct from ______'s North Magnetic Pole. The South Pole is the other point where ______'s axis of rotation intersects its surface, in Antarctica. ______ rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars (see below). ______'s rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on ______'s rotation. Atomic clocks show that the modern day is longer by about 1.7 milliseconds than a century ago, slowly increasing the rate at which UTC is adjusted by leap seconds. Analysis of historical astronomical records shows a slowing trend; the length of a day increased by about 2.3 milliseconds per century since the 8th century BCE.Scientists reported that in 2020 ______ had started spinning faster, after consistently spinning slower than 86,400 seconds per day in the decades before. On June 29, 2022, ______'s spin was completed in 1.

Most maps are dynamic and interactive.

The word 'map' comes from the medieval Latin: Mappa mundi, wherein mappa meant 'napkin' or 'cloth' and mundi 'the world'.

The history of cartography traces the development of mapmaking technology in human history.

Geographic maps of territory have a short tradition and exist only from ancient times.

Maps have been one of the most important human inventions for centuries, allowing humans to explain and navigate their way through the world.
