What causes the seasons on Earth?

This is a more complex answer than most might think. Climate (long term weather) and climate change are a basic factor of 3 main things Obliquity (axial tilt) Precession
Rotation (elliptical eccentricity,) They are also referred to as Milankovitch cycles named for the Serbian scientist that theorized and later proved his idea of cyclical climate changes with 26k 41k and 100k events which later were mathematically shown to coincide almost exactly with earths climate history. The Earth's rotation around its axis, and revolution around the Sun, evolve over time because gravitational interactions with other bodies in the solar system. a few cycles are dominant. Earths tilt and the wobble Seasons are not caused by its proximity to the sun, rather they are caused by its tilt (obliquity) and its wobble (precession) also causes chanhes in the magnetic declination of our poles.

Think of an apple stab it with a pencil and tilt it 20 or so degrees, as the earth rotates amd revolves and wobbles the poles change place in angle to the sun, move your pencil from front to back


What relationship between earth and the sun causes the seasons?

The Earth is tilted on its axis. 'Summer' (the warmest season) occurs when a hemisphere, either the northern hemisphere or the southern hemisphere, is tilted towards the Sun and thus receives more direct sunlight (the Sun is closer to the zenith and is above the horizon longer).

A common misconception is that the seasons have to do with the Earth being closer to the Sun due to the elliptical nature of its orbit. The orbit is elliptical and the Earth is closest to the Sun [aphelion] in early January, farthest away [perihelion] in early July. This has a minor effect on the seasons, but more important is the number of days and weeks the Sun is higher in the sky; near perihelion for the northern hemisphere (although the Sun is further away) the atmosphere has the opportunity to heat up more.

Twice during the year (spring and fall Equinox - around the 20th of March and September respectively), the Sun appears to circle more directly over the equator [the axis of the Earth is in a plane perpendicular to the orbit], and most areas of the globe receive similar amounts of daylight. The poles are exceptions, with extremely long periods of the Sun either above or below the horizon.

From late December to late March, the Southern Hemisphere experiences 'summer' while the Northern Hemisphere experiences 'winter'. From late June to late September, the position is the other extreme, and it is summer in the Northern Hemisphere, winter in the Southern.

These yearly changes in insolation (incoming energy from the Sun) cause the seasons, in conjunction with the prevailing directional wind patterns, ocean areas, currents, and pressure systems which all affect the local climate.

The tilt of the Earth in combination to its position during its orbit around the Sun.

Meteorology and Weather

Does spring start a day early in 2020?

In the United States, the vernal equinox, which signifies the start of astronomical spring in the northern hemisphere, actually happens on March 19, 20, or 21 each year. We haven’t had a March 19 equinox since 1896, and we won’t have a March 21 equinox until 2101.

I say it marks the beginning of astronomical spring because meteorological spring (based on weather patterns) starts March 1.

Astronomical spring is a little harder to explain. The Earth’s axis is always tilted at about 23 degrees, meaning that depending on where it is in its orbit, one hemisphere or the other is closer to the sun. The equinoxes (the vernal equinox in March and the autumnal equinox in September) mark the points in the orbit where neither hemisphere is tilted toward nor away from the sun, meaning day and night are nearly equal.


What is the order of the seasons?

The seasons begin with Spring, Summer, Fall (Autumn), and then finally Winter. This then becomes a cycle.

Earth Sciences

What causes the Earths seasons?

God made earth and all! It seems we maybe over effecting our earth and possibly causing our own changes to it.

All that do Believe in God have lives filled with LOVE!

Atheists cannot feel anymore than each of their own LUST for only each of their own wants!


Why does the Sun change position in the sky over different seasons?

The seasons are due to the motion of the Earth around the Sun. So, it may not be surprising that the Sun's position in the sky changes over seasons, due to the motion of the Earth around the Sun. The explanation is simple. All stars in the sky are moving, but the distant stars are so far away that we cannot detect appreciable motion (even when the Earth moves around the Sun). As a result, the positions of distant stars in the sky are fixed. At any single moment the Sun can be projected as a dot onto the night sky by extending the line that connects the Earth and the Sun (the line of sight) all the way to the sky. As the Earth orbits around the sun the line of sight changes direction and since the distant stars are fixed in the sky, the position of the Sun with respect to the distant stars changes.


The main factor that changes the Sun's position in the sky is that the earth's axis of rotation is tilted. This means that the sun is higher above the horizon in the summer months than in the winter.

Climatology and Climate Changes

What months are considered to be winter?

The actual period of winter in the northern hemisphere is 21 December through 21 March. In the southern hemisphere, winter is from 21 June through 21 September, while the northern hemisphere is experiencing summer.

Generally speaking, most people in the northern hemisphere think of winter as being in December, January and February while in the southern hemisphere, many people consider winter to be in June, July and August.

In fact in Australia (at least) winter officially begins on 1st June and ends on 31st August.

Meteorology and Weather

What season does the sun cast the shortest shadow?

Summer. For places between the tropics it's a bit different with zero shadow at times.

When was the first day of spring 2009?

Spring comes in between the 19th to the 23rd of March and at different times. It changes on a yearly basis because the first official day of spring is the (Spring) Vernal Equinox. This is when the sun is directly above the equator. It rises due East and sets due West and does not do so on the exact same day every year, since the calendar is not exactly 365 precise days every single year.

In 2009, spring arrived on March 20; the sun was above the equator, and crossed to the northern hemisphere at approximately 11:47p.m.

The first day of spring in the Northern Hemisphere this year (2009) was March 20. The equinox was at 5:48 GMT. In general, the four seasons correspond to the relative position of the sun to the earth. Meteorological determination of spring is calculated according to when the sun passes through the equatorial plane. When going from winter to spring, the sun is moving north; as soon as the sun crosses the equator, we call it spring. == == The above applies to places north of the equator.

"Spring", a time of melting and new growth, occurs about September-November in places south of the equator, e.g., Australia, New Zealand, Africa, Brazil...).

The official date of spring south of the equator (corresponding to the first official day of fall in places north of the equator) would be around September 20/21, depending on when the sun crosses the equator. Countries such as Australia and New Zealand, however, designate the first day of September as the official first day of spring.

North Pole

What kind of sun rays hit the north and south pole?

Electromagnetic waves hit both the north ans south poles. These are the same rays that hit the rest of the Earth. The difference is in the angle at which they hit. They are more oblique than at the equator, and so they get spread over a bigger area and so heating is less intense.


When does summer vacation end in Miami?



Does any place on the equator have equal day and night on June solstice?

Anywhere around the equator, the days and nights are always about equal.


When is snake season in Australia?

Summer is the worst time for snakes in Australia, but they begin to emerge around September, and tend to stay more active until about April, particularly if the weather is warm.

Baseball History

What month does baseball season start?

It depends on if you're talking about Spring Training or the regular season. Spring Training starts in late February and the regular season begins in April.

Climatology and Climate Changes

What countries experience the four seasons?

By some definitions, all countries experience four seasons. The variation in the weather and temperature depends, largely, on the latitude of the country.

However, we tend to say that most tropical countries experience only two seasons: wet and dry. This is because temperature varies very little throughout the year, whereas the position of the inter-tropical convergence zone causes one or more distinct wet seasons. This is far more important to these people than slight changes in temperature because the timing of the rain is so important for agriculture.

Climatology and Climate Changes

What countries experience 4 seasons?

A lot of countries experience 4 seasons. All of them are situated away from the Equator, above the Tropic of Cancer and Capricorn. Some examples are the Countries on the Northern America, mainly USA and Canada, most or all of the European countries. Some countries in Asia experience 4 seasons too, such as China, Korea (North and South), Japan. Australia and New Zealand experience 4 seasons too, but their cycle is different from the countries located on the Northern Hemisphere of the Earth. When the countries in the Northern Hemisphere experience summer, they will experience winter and vice versa.

Respiratory System

Jokes and Riddles

If April showers bring May flowers what do Mayflowers bring?

  • Mayflowers bring pilgrims.
  • May Flowers will bring June Bugs.

The original poem by Sara Coleridge:

January brings the snow,

Makes our feet and fingers glow.

February brings the rain,

Thaws the frozen lake again.

March brings breezes loud and shrill,

Stirs the dancing daffodil.

April brings the primrose sweet,

Scatters daises at our feet.

May brings flocks of pretty lambs, Hay Fever

Skipping by their fleecy dams.

June brings tulips, lilies, roses,

Fills the children's hand with posies.

Hot July brings cooling showers,

Apricots and gillyflowers.

August brings the sheaves of corn,

Then the harvest home is borne.

Warm September brings the fruit,

Sportsmen then begin to shoot.

Fresh October brings the pheasants,

Then to gather nuts is pleasant.

Dull November brings the blast,

Then the leaves are whirling fast.

Chill December brings the sleet,

Blazing fire, and Christmas treat.
