No, the sun shines differently at different spots of the earth. Because Earth is spherical, the Sun’s rays hit the equator (the imaginary line separating the northern and southern halves of Earth) directly and the rest of Earth at various angles.
Because the equator receives the most direct sunlight all year, the equatorial regions have a relatively consistent, temperate climate. Direct rays are the shortest and strongest, which is why the climate at the equator is generally hot.
Angled rays are longer and weaker, so Earth’s North and South Poles remain cold.
