Because the Earth is spinning - at about 1000 miles per hour at the equator.
The equator has a tilt of 0 degrees relative to the plane of the Earth's orbit around the Sun. This means that it is perpendicular to the axis of the Earth's rotation, and divides the Earth into the Northern and Southern Hemispheres.
There would be no four seasons if the earths axis was not titled.
Approximately 23°. As a matter of interest, the Tropics of Cancer and capricorn are 23° from the Equator, these representing the most northerly/southerly points on the Earth where the Sun can be directly overhead. This is due to that tilt of the earth.
Celestial Equator
Earth's equatorial plane is an imaginary plane that divides the Earth into two equal halves, creating the equator. It is perpendicular to the Earth's axis of rotation, which means it is horizontal in relation to the planet's poles.

The tilt of earths axis makes the equator appear to be sideways.
Pretty much...It is just the line perpendicular to the axis of the earth
Because the Earth is spinning - at about 1000 miles per hour at the equator.
The transverse axis is perpendicular to the conjugate axis.
The equator has a tilt of 0 degrees relative to the plane of the Earth's orbit around the Sun. This means that it is perpendicular to the axis of the Earth's rotation, and divides the Earth into the Northern and Southern Hemispheres.
The Earth's axis is tiled 23.4 degrees. It tilts away from the perpendicular of its orbital plane which is why seasons are produced on Earth. The earth rotates on its axis 266.26 times each year.
The plane, which passes through the equator of the earth, perpendicular to its axis of rotation, and equidistant from its poles -- is known as Euuatorial plane
During an equinox, neither the North nor the South end of Earth's axis is tilted away from the Sun. This is because during an equinox, the tilt of Earth's axis is perpendicular to the Sun's rays, causing equal illumination of both the Northern and Southern Hemispheres.
The transverse plane is perpendicular to the longitudinal axis.
The plane upon which the Earth travels round the Sun is called the ecliptic. It is only when two bodies are on this plane, and in line with the Sun, that an eclipse is observed. Hence the name ecliptic. The Earth's spin axis is always oriented about 23.4 degrees from the ecliptic plane. The Earth's spin axis is never perpendicular to the Sun's rays. You may be referring to the Sun being directly overhead at the Equator twice per year.
