Earth's Rotation and Axis Tilt

Study Notes

Definition: Earth's rotation is the movement of the Earth on its axis, causing day and night cycles.
Period: The Earth takes approximately 24 hours to complete one rotation on its axis.
Direction: The Earth rotates from west to east, meaning the Sun appears to rise in the east and set in the west.

Definition: The axis tilt refers to the angle at which the Earth's axis is tilted relative to its orbital plane around the Sun.
Angle: The axis tilt is approximately 23.5 degrees.
Importance: The axis tilt is responsible for seasonal changes on Earth.

Causes: Day and night cycles are caused by the Earth's rotation, as different parts of the planet face towards or away from the Sun.
Duration: A day is approximately 24 hours long, with day and night periods of roughly 12 hours each at the equator.
Variations: The duration of day and night cycles varies depending on the latitude and time of year.

Causes: Seasonal changes are caused by the Earth's axis tilt and its orbit around the Sun.
Types: There are four main seasons: spring, summer, autumn (or fall), and winter.
Characteristics:
- Spring: Mild temperatures, increasing daylight hours.
- Summer: Warmest temperatures, longest daylight hours.
- Autumn: Cooling temperatures, decreasing daylight hours.
- Winter: Coldest temperatures, shortest daylight hours.
Seasonal changes vary:
- By latitude, with more extreme seasonal changes at higher latitudes.
- By hemisphere, with opposite seasons in the Northern and Southern Hemispheres.

Earth rotates on its axis, causing day and night cycles to occur every 24 hours.
The rotation direction is from west to east, resulting in sunrise in the east and sunset in the west.

The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbital plane around the Sun.
This tilt is responsible for seasonal changes on Earth, which vary throughout the year.

Day and night cycles are a result of the Earth's rotation, where different parts of the planet face towards or away from the Sun.
A standard day is 24 hours long, with day and night periods of roughly 12 hours each at the equator.
However, the duration of day and night cycles varies depending on the latitude and time of year.

Seasonal changes are caused by the combination of the Earth's axis tilt and its orbit around the Sun.
There are four main seasons: spring, summer, autumn (or fall), and winter, each with distinct characteristics.
In spring, temperatures are mild, and daylight hours increase.
Summer is the warmest season, with the longest daylight hours.
Autumn brings cooling temperatures, with decreasing daylight hours.
Winter is the coldest season, with the shortest daylight hours.
The severity and nature of seasonal changes vary by latitude, with more extreme changes at higher latitudes.
Additionally, the seasons are reversed between the Northern and Southern Hemispheres.
