What causes day and night on the Earth?
The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time. via

What is day/night called?
The line that separates day and night is called the terminator. It is also referred to as the "grey line" and the "twilight zone." It is a fuzzy line due to our atmosphere bending sunlight. It is commonly thought that while half of the Earth is covered in darkness, the other half is covered in sunlight. via

What would happen if the Earth stopped rotating?
At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes. via
Why does it get dark?
The sun's light pours outward to illuminate every portion of our solar system so that the space around the sun is almost entirely flooded with light. But there are dark places. These are in the shadows of planets, moons and other objects in orbit around the sun. And it's these shadows that create night. via
Why do we need day and night?
We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles. The Earth spins slowly all the time, but we don't feel any movement because it turns smoothly and at the same speed. via

What things do we see at night?
THE PLANETS. The brightest objects visible in the night sky are Mars, Venus, Jupiter and Saturn. Planets move around the sun at different speeds. When combined with Earth's own movement, that means you can see different planets at different spots in the sky at different times of the year. via
Which country has half day and half night?
This causes the part of Norway located in the Arctic region at the North Pole of Earth to move very close to the Sun and during this time the length of the day increases. It can be said that it almost never subsides. Night falls in Norway's Hammerfest at this particular time of year. via
Why does it get dark at night 1st grade?
As Earth rotates, the half that faces away from the sun experiences night. Without the sun's rays, it is dark. via
Where does night meet day?
The event, known as equinox, is eagerly awaited by space enthusiasts as it takes place only twice a year. Marking the beginning of spring, the sun will cross the plane of the earth's equator on Monday morning, making day and night of approximately the same duration. via
What Causes season?
Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. In June, when the Northern Hemisphere is tilted toward the sun, the sun's rays hit it for a greater part of the day than in winter. via
Where does the sun goes at night?
From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles. via
What are the reasons for the seasons?
Extending the Learning
Remind students that the two reasons seasons occur are the tilt of a planet's axis and its orbit around the sun. Ask: A planet's axis might have a smaller or larger tilt than Earth's. via
