In the Northern Hemisphere, summer is the hottest season of the year. It usually begins around June 21 and lasts until September 21. In the Southern Hemisphere, things are reversed and it is called winter. The vernal equinox marks the first day of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. Let’s take a look at some facts about these seasons and their significance…

Vernal Equinox: The Start of Spring

The vernal equinox marks the first day of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. The word equinox means “equal night” because at this time the Sun is directly above the equator and night and day are of the same length in all parts of the world. The spring equinox occurs around March 20. This is the time when the Sun crosses the celestial equator, heading northwards and marking the start of spring in the Northern Hemisphere. The autumn equinox occurs around September 22. This is the time when the Sun crosses the celestial equator, heading southwards, marking the start of autumn in the Southern Hemisphere.

Spring Equinox

Spring is the time when plants begin to grow. This is due to an increase in temperature, which brings warmth and sunlight. In many places, the ground thaws and snow melts. As the water flows, it brings nutrients to the roots of plants. This is the time when some birds start to build their nests. Bees also produce more flowers, which they use to make honey. The first flowers and buds appear on trees. The spring equinox occurs when the Sun crosses the equator, which marks the start of spring in the Northern Hemisphere. This is the time when day and night are equal in length on the equator.

Summer Solstice and Day

Summer Solstice (or the Summer Solstice) is the longest day of the year. During this time, the Sun is at its highest point in the sky, and there is no night at the equator. In the northern hemisphere, the summer solstice falls between June 20 and June 22. This is the time when the Sun is at its highest point in the sky, and there is no night at the North Pole. The summer solstice marks the hottest part of the year. At this time, the days are longest and the nights are shortest. In the Southern Hemisphere, this is the first day of autumn. The summer solstice is the day when the Sun has the most power. This is why many people choose to celebrate the summer solstice. People living in the northern hemisphere celebrate the summer solstice at the start of summer. People living in the southern hemisphere celebrate the summer solstice at the start of autumn.

Autumn Equinox – Start of Autumn

Autumn marks the start of autumn in the Northern Hemisphere and spring in the Southern Hemisphere. This is the time when the Sun starts to move southwards and the days become shorter. In some places, trees lose their leaves and the weather becomes cooler. The autumn equinox occurs when the Sun is directly above the equator, marking the start of autumn in the Northern Hemisphere. During this time, day and night are equal in length all over the equator.

Facts about the Seasons

There are four seasons in the year, which are spring, summer, autumn, and winter. Each season lasts about three months, and the seasons are broken down even further into months. The seasons are caused by the Earth’s tilt on its axis, which creates a change in the amount of sunlight received by the northern and southern hemispheres. The Earth travels around the Sun at an angle and as it does so, it rotates on its axis. During this process, the northern hemisphere is tilted towards the Sun. This means the northern hemisphere receives more sunlight than the southern hemisphere. This is why summer is hotter in the northern hemisphere and winter is colder.

Conclusion

The vernal equinox marks the first day of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.
