Day and night Flashcards
What causes day and night on Earth?
Day and night are caused by the Earth’s rotation on its axis
How long does it take for the Earth to complete one full rotation on its axis?
It takes approximately 24 hours.
What is the Earth’s axis, and how is it oriented
The Earth’s axis is an imaginary line that runs from the North Pole to the South Pole, tilted at an angle of approximately 23.5 degrees relative to its orbit around the Sun
In which direction does the Earth rotate?
it rotates from west to east
How does the direction of Earth’s rotation affect the Sun’s apparent movement across the sky?
The Sun appears to rise in the east and set in the west due to the Earth’s rotation from west to east
What happens when a part of the Earth faces the Sun?
It experiences daytime, with the Sun’s rays illuminating and warming that part of the planet.
What occurs when a portion of the Earth is turned away from the Sun?
It experiences nighttime, with darkness and cooler temperatures due to the absence of direct sunlight.
How does the tilt of the Earth’s axis affect the length of day and night throughout the year?
The tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year, leading to longer days and shorter nights in summer and shorter days and longer nights in winter
Why is understanding the Earth’s rotation and tilt important?
It helps us appreciate the cycle of day and night and how it influences natural processes, biological rhythms, and seasonal changes on Earth.
