Earth MCQ Question and Answer | Geography MCQ Question

Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Continetal Drift theory was proposed by Alfred wegner in 1912. It stated that continents have changed their position and initially there was only one big continent named Pangea. Although he was unable to explain the force behind the drifting of continents.

Shield is the region of stable landmass occupied by resistant rocks of igneous origin, showing resistant to geomorphic processes e.g. Canadian Shield.

Roughly, 0.47 percent of insolation reaches the Earth's surface. The rest is either reflected and scattered back to space through its interaction with clouds, water vapour, dust and pollen, known collectively as aerosols or it is absorbed by clouds and gaseous elements and hence heats the atmosphere.

Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counter clockwise. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where Earth's axis of rotation meets its surface.

The Equator is exactly halfway in between the poles. So it wouldn't make any sense for a day on the equator to be longer when one of the poles is tilted towards the Sun, and shorter when the other one is. The days and nights remain equal here throughout the year.

If the earth's axis had not been inclined the seasons would not have occurred and poles would not have a continuous day.

The sun is never overhead at any time in the North Temperate Zone, South Temperate Zone and North Frigid Zone.

The earth revolves round the sun and rotates round its own axis. The rotation of the earth causes day and night.
