Why is the tropical climate hot?

Regions with tropical climate are hot due to the following reasons:

• The sun shines more directly on the tropics than on higher latitudes which makes the tropics warm

• The vertical direction is perpendicular to the Earth’s axis of rotation at the equator, while the axis of rotation and the vertical are the same at the pole; this causes the Earth’s rotation to influence the atmospheric circulation more strongly at high latitudes than low.
