Primavera: ¿qué causa la primavera?

The video explains how seasonal changes are influenced by Earth's tilt and its revolution around the Sun. It highlights the differences in seasonal changes between regions near the equator and those further north. The Earth's axis remains tilted in the same direction as it orbits the Sun, causing variations in sunlight received by the Northern Hemisphere, leading to different seasons. The Spring Equinox marks a time when both hemispheres receive equal sunlight, signaling the start of spring, which transitions into summer as days become longer and warmer.

Why are seasonal changes more noticeable in northern regions compared to areas near the equator?

• Because the Earth is flat in northern regions.

• Because the equator has no seasons.

• Because the Earth's axis is tilted.

• Because the Sun is closer to the northern regions.
