Day and Night - Seasons Flashcards

Orbit: The pathway an object follows while revolving around another, crucial for understanding planetary movements.
Rotate: Describes the action of spinning around an axis, significantly impacting day and night cycles.
Revolve: Refers to the motion of an object traveling around a central entity, essential for the Earth's relationship with the sun.
Axis: An imaginary line through the Earth from pole to pole, fundamental to understanding Earth's rotation and tilt.

Causes of Seasons: Results from the Earth's axial tilt and its revolution around the sun, creating variations in light and temperature throughout the year.
Earth's Motion:
- Rotation on Axis: A full rotation takes 24 hours, leading to the day-night cycle.
- Revolution around the Sun: It takes 365 days for the Earth to complete one orbit, defining a year.
Day and Night: Caused by Earth's rotation, with daylight occurring on the sunlit side and nighttime on the opposite side.

Monthly Cycle: The moon orbits the Earth approximately every 29.5 days, contributing to the concept of months.
Seasonal Changes:
- During the northern hemisphere's summer, the Earth is tilted toward the sun, resulting in increased light and heat.

Phase: Represents a segment of a cycle, important for understanding lunar phases and seasonal changes.
Cycle: A repeating pattern observed in natural phenomena, such as lunar phases and seasonal shifts.
Waxing: Indicates the increase in size or brightness of the moon, moving from new to full phase.
Waning: Refers to the decrease in size or brightness of the moon, transitioning from full to new phase.
