Third-grade students have an opportunity to explore the concepts of seasonal weather patterns and why they occur in a three-dimensional learning module from the Smithsonian Science Education Center titled, How Do Weather and Climate Affect Our Lives? This module is part of the Smithsonian Science for the Classroom series. The Pyramid of the Sun is the world’s third largest pyramid. Each year to celebrate spring, thousands of people visit the Pyramid of the Sun to ascend the steps and raise their arms toward the sky to receive spiritual energy from the Sun. Browse 5,772 authentic spring equinox stock photos, high-res images, and pictures, or explore additional spring equinox england or spring equinox sun stock.

There are two popular places in Mexico to celebrate an equinox: Chichen Itza and Teotihuacán. Direct sunlight shines on the equator, so the length of day and night is nearly equal for both hemispheres.ĭuring an equinox, the Sun shines directly on Earth’s equator, resulting in nearly equal amounts of daylight and darkness. During the equinox, the length of night and day are approximately equal all over the world. This spectacular phenomenon only happens twice a year, once in the Spring, and once in Autumn. During an equinox the tilt of Earth's axis and Earth's orbit around the Sun are positioned such that the axis isn't tilting one hemisphere toward or away from the Sun.

Think of them like events happening as our planet make its journey around the Sun. At the equator, an equinox results in about 12 hours of daylight and 12 hours of night.Įquinoxes and solstices are caused by Earth’s tilt on its axis and the ceaseless motion it has while orbiting the Sun. The Sun will pass directly above the equator, bringing nearly equal amounts of day and night on all parts of Earth.
