What are the seasons in the northern hemisphere?
A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter —follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly. In the Northern Hemisphere, winter generally begins on December 21 or 22.
What are the four seasons?
The four seasons are Spring, Summer, Autumn, and Winter. Seasons are created by the earths yearly orbit (365.25 days) around the sun and the tilt of the earth's axis (23.5 degree tilt) as it orbits around the sun.
Why do we observe different seasons in different hemispheres?

Why does the Northern Hemisphere have 4 seasons?
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Do all countries have 4 seasons?
But not all countries have seasons. Countries near to the equator - the line which goes round the middle of the earth - have very mild seasons. The weather stays almost the same temperature all the year round.
Why are there 4 seasons?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
What equinox means?
Definition of equinox 1 : either of the two points on the celestial sphere where the celestial equator intersects the ecliptic. 2 : either of the two times each year (as about March 21 and September 23) when the sun crosses the equator and day and night are everywhere on earth of approximately equal length.

Why do seasons occur?
Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth’s axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis.

What is the transition phase of spring and fall?
During spring and fall, the earth is in a transition phase. What usually marks the occurrence of spring and fall astronomically is the equinox. The equinox occurs when the sun is directly focused on the earth’s equator and causes 12 hours of daytime hours and 12 hours of nighttime hours across the entire earth (in Latin, equinox means equal night) . There are two types of equinoxes that occur: the vernal and the autumnal. The vernal equinox marks the beginning of astronomical spring for the Northern Hemisphere and the beginning of astronomical fall for the Southern Hemisphere. As time passes, the Northern Hemisphere gradually receives more of the sun’s rays and also experiences longer daylight hours. The autumnal equinox marks the beginning of fall in the Northern Hemisphere and spring in the Southern Hemisphere. The Northern Hemisphere gradually receives less of the sun’s rays over time and also experiences less daylight hours. In addition to revolving around the sun, the earth rotates counter-clockwise on its own axis. This rotation allows us to experience day and night.
What are the two types of equinoxes?

The date at which the Earth’s tilt points most directly toward the Sun is called the summer solstice, and, conversely, the date at the Earth’s tilt points most directly away the Sun is called the winter solstice. In the Northern Hemisphere, these are the longest and shortest days of the year, respectively. This means that in June, July, and August, ...
Which hemisphere receives less sun rays?
The Northern Hemisphere gradually receives less of the sun’s rays over time and also experiences less daylight hours. In addition to revolving around the sun, the earth rotates counter-clockwise on its own axis. This rotation allows us to experience day and night.

This means that in June, July, and August, when we see our summer heat in North Carolina, the Southern Hemisphere is actually experiencing winter! When we experience winter in the Northern Hemisphere (December, January, and February), it’s because the Northern Hemisphere is tilted away from the sun and receives less radiation.
Why do seasons occur on Earth?
Seasons occur on Earth because Earth is tilted and it travels around the Sun once each year. As Earth travels, different parts of it slant or tilt toward the Sun. This affects the amount of light and heat that the different parts of Earth receive.
What is the third season?
Autumn is the third of the four seasons. By September Earth has moved so that the equator receives the most sunlight. Everywhere on Earth, except the North and South poles, days and nights are of equal length. During this time, autumn occurs in the Northern Hemisphere, while spring begins in the Southern Hemisphere.

Why do the northern and southern hemispheres have opposite seasons?
This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun than the other, and this exposure alternates as the Earth revolves in its orbit.
Why are the four dates considered seasonal midpoints?
Because of seasonal lag due to thermal absorption and release by the oceans, regions with a continental climate, which predominate in the Northern Hemisphere, often consider these four dates to be the start of the seasons as in the diagram, with the cross-quarter days considered seasonal midpoints.
Why do the seasons occur 7 weeks later?
The heights of these seasons occur up to 7 weeks later because of seasonal lag. Seasons, though, are not always defined in meteorological terms. In astronomical reckoning by hours of daylight alone, the solstices and equinoxes are in the middle of the respective seasons.
How many seasons are there in China?
The traditional calendar in China has 4 seasons based on 24 periods known as solar terms. The four seasons chūn ( 春 ), xià ( 夏 ), qiū ( 秋 ), and dōng ( 冬 )—universally translated as "spring", "summer", "autumn", and "winter"—each center around the respective solstice or equinox. Astronomically, the seasons are said to begin on Lichun ( 立春, "the start of spring") on about 4 February, Lixia ( 立夏) on about 6 May, Liqiu ( 立秋) on about 8 August, and Lidong ( 立冬) on about 7 November. These dates were not part of the traditional lunar calendar, however, and moveable holidays such as Chinese New Year and the Mid-Autumn Festival are more closely associated with the seasons. It forms the basis of other such systems in East Asian lunisolar calendars .
How do indigenous people define seasons?
Indigenous people in polar, temperate and tropical climates of northern Eurasia, the Americas, Africa, Oceania, and Australia have traditionally defined the seasons ecologically by observing the activity of the plants, animals and weather around them. Each separate tribal group traditionally observes different seasons determined according to local criteria that can vary from the hibernation of polar bears on the arctic tundras to the growing seasons of plants in the tropical rainforests. In Australia, some tribes have up to eight seasons in a year, as do the Sami people in Scandinavia. Many indigenous people who no longer live directly off the land in traditional often nomadic styles, now observe modern methods of seasonal reckoning according to what is customary in their particular country or region.
