Assuming you mean "why": if the Sun appears to set, that is the result of Earth's rotation.
The rotation of the earth is what causes the sun to appear to set
No, the sun does not technically set into the sea. The Earth revolves around the sun which makes the sun appear to set into the sea especially when you are watching a sunset at the beach.
West. This is due to Earth's rotation from west to east, causing the sun to appear to move across the sky and set in the western direction.
Because the Earth rotates on its axis, constantly spinning.
The earth rotates in a clock wise motion thus making the sun rise in the east and set in the west.
The Sun is at the centre of our solar system. the Earth not only orbits the Sun - but also spins on its axis. The spinning of the earth presents a different area of the planet's surface towards the Sun - making the sun appear to rise and set.
From an observer on Earth, both the sun and the moon appear to rise in the east and set in the west due to the rotation of the Earth. The sun and the moon also appear to move across the sky in an arc, with the sun following a daily path and the moon following a monthly path.
The Sun doesn't really rise and set; the Sun sits there in the center of our solar system, unmoving. It is the Earth spinning - and us with it - that makes the Sun appear to rise in the East and set in the west.
The Sun, Moon and stars only appear to "rise" and "set" because we live on a spinning Earth. The Earth spins west-to-east once every 24 hours.
The sun, moon, and stars all appear to rise in the east and set in the west due to the Earth's rotation on its axis. This rotation causes all celestial bodies to appear to move across the sky from east to west. The moon's own orbit around the Earth affects its position, but it does not directly impact the sun and stars.
The sun appears larger from the Earth. The reason is that the Earth is closer to the sun.
The rotation and revolution of earth are responsible for it, but sometimes there is lunar eclipse.
