A traveller experiences a change in climate while travelling from the equator toward the pole because of the way the Earth is tilted on its axis. At the equator, the Sun’s rays hit the Earth’s surface directly, making the region hotter. As one moves toward the poles, the angle at which the Sun’s rays hit the Earth becomes shallower, resulting in less direct sunlight and cooler temperatures. Additionally, the circulation of the Earth’s atmosphere and ocean currents also play a role in determining the climate of a region.
