A) The Earth rotates upright
B) The Earth rotates while tilted on its side
C) The Earth speeds up and slows down while spinning
5) How many degrees is the equator of the Earth tilted relative to ecliptic?

10) Why do we see stars shine only at night?
Pasagot nga po ng tama lahat^_^
10. Stars are present both day and night.
( 1 )
As time passes, the stars rise in the east (just like the sun). But notice that they rise diagonally, not straight up. The diagonal goes from north (left) to south (right). After a few hours, these same stars will appear high in the southern sky. Turning to face south, we see that the stars there are moving from left (east) to right (west)

Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
( 3 )
The Earth is not motionless in space, but is subjected to different movements. The most well-known are the rotational movement around its own axis, which determines the alternation of day and night and the apparent movement of the sky above our heads, and the revolution around the Sun in a slightly elliptical orbit. Hence, it moves and acts like a spinning top.

Earth rotates on its axis; this causes us to experience day and night. But Earths axis is tilted 23.5 degrees (the angle is measured between Earths equatorial plane and the plane in which it orbits our Sun).
( 5 )
The ecliptic is the path that the Sun and other objects in the Solar System appear to follow in the sky, that is tilted from the equator at 23.5 degrees. This is because the axis that Earth is spinning on, is tilted at that angle compared to the plane of the Solar System.
( 6 )
During the equinoxes every location on our Earth (except the extreme poles) experiences 12 hours of daylight and 12 hours of darkness.
( 7 )
Earth rotates on its axis; this causes us to experience day and night. But Earths axis is tilted 23.5 degrees which causes the Earth to have day and night.
( 8 )
Different places in the Earth experiences different lengths of night and day. The 12 hours of day and 12 hours of night happens only in places near the equator, for example the Philippines.
( 9 )
Sunlight falls only on one side of the Earth. This side of the planet will be experiencing daylight. Because the Earth is rotating, the opposite side of the Earth away from the Sun will be experiencing night. Since the Philippines is near the equator or imaginary line drawn around the earth equally distant from both poles, it may be possible to have exactly 12 hours of day and 12 hours of night.

Stars can only be seen throughout the night but not by day since the suns light is so bright that we cant see dimmer stars.
