What are the causes of the seasons?
The four divisions of the year (spring, summer, fall and winter) are marked by weather patterns and hours of daylight in a particular region.
These patterns are a result of Earth’s 23.5° tilt of axis and its changing position as it orbits the Sun.
4
Earth's Axis is Tilted
Earth spins around its axis once every 24 hours
The axis is an imaginary line on which Earth rotates.
This imaginary line intersects the surface of Earth at the North Pole and South Pole.

Earth's Axis is Tilted
As Earth orbits around the Sun, it spins on its axis, which is tilted 23.5° relative to the plane of its orbit.
Earth’s tilt of the axis points in the same direction in space but changes its position relative to the Sun depending on where it is located during its path of orbit

What does this have to do with seasons?
During the month of June, the Northern Hemisphere and North Pole point toward the Sun.
This causes temperature increases and changes in the atmosphere in the Northern Hemisphere that indicate the season of summer.
10
What does this have to do with seasons?
During the month of December, the Southern hemisphere and South Pole point toward the Sun.
This causes temperature increases and changes in the atmosphere in the Southern Hemisphere that indicate the season of summer.

Light Intensity
Light is a form of energy that can travel through space.
Light energy can be seen by the human eye and is given off by things such as stars, light bulbs, lasers, and hot objects.
Light energy is also used by plants to produce food through the process of photosynthesis.
14
Light Intensity
When there is more light energy, plants are able to produce more food, which helps them grow.
Light can be measured to determine its intensity or how much energy is hitting a surface.
Light travels in a straight line until it hits something else that may block or reflect the light in a different direction.
15
Light Intensity
When light travels in a straight line from the Sun to Earth and hits the surface at a 90° angle, it is the most intense and transfers the most energy.
This energy is known as solar radiation.
When light hits the surface of Earth at a smaller angle, less energy and solar radiation is transferred because the light is spread out over a larger area of Earth’s surface.

Latitude
Latitude are imaginary lines that run north to south to measure the distance north or south of the equator.
The equator is a line of latitude that divides Earth into two equal hemispheres and is located at 0°.
18
Latitude
The angle between the North Pole and the equator is 90° and forms a right angle, thus creating the latitude of 90°N (north).
The same is true for the South Pole, which creates a latitude of 90°S (south).
The latitude of any particular location on earth is measured by the degrees of the angle between that location and the equator.

20
Latitude
The farther away from the equator, the greater the latitude will be.
There are four lines of latitude other than the equator.
These lines have special names and are marked on most globes to create regions with similar conditions during the seasons.

Multiple Choice
22
Latitude
The Arctic Circle and Antarctic Circle are the most north and south of these latitudes, with the Arctic Circle found at 66.5°N and the Antarctic Circle found at 66.5°S.
The areas between these circles and the North and South Poles are where you can find the coldest temperatures and most extreme differences between the seasons.
The Tropics are from 23.5 degrees north to 23.5 degrees south
