The Earth's rotation on its axis is not directly affected by gravity except that gravity holds Earth together as a sphere.
Earth's revolution round the Sun is an "orbit" which obeys the laws of gravity.
There is also a slight transfer of the rotational energy of the Sun to Earth's revolution speed. The Sun's spin is slowing and Earth is moving away form the Sun a little. {Note, this effect is far more pronounced between the Earth and the Moon].
The (centripital) force due to rotation is at its greatest at the equator, if you weigh 100 kg, the force of gravity on you = approx. 982 n anywhere on earths surface, the centripetal force at the equator = 3.4 n
Coriolis effect
The earths rotation effects whether it is night or day (so you'll see the moon at night).
The moons gravity 'pulls' the earths water creating a 'tide.'
Gravity is pretty constant figure anywhere on earth, essentially its dependent on your distance from the center of gravity of the earth, nominally it will produce an acceleration of 9.81((m/s/)/s) at the earths surface. Gravity is dependent on mass and independent of motion , ie mass of earth attracting mass of person , attraction being proportional to total mass of both and distance between their centers of gravity. However , a very small opposing acceleration outwards is experienced because you are rotating about the earths axis (centrifugal action) , its maximum effect is on the equator and zero effect at the poles. this acceleration can be calculated from: a = (v^2)/r where: a = acceleration ((m/s)/s) v = velocity (m/s) r = radius or normal distance from earths axis (m)
Earth's rotation causes a centrifugal force that slightly counteracts gravity at the equator, making objects slightly lighter there compared to the poles. This effect is very small, however, and does not significantly impact our daily lives or activities.
coriolis effect
The Earth's rotation turns the polar high pressure systems westward as they move from the poles (westerlies), and the subtropical high pressure systems eastward as they move toward the equator (tropical easterlies).

By slowing down the earths rotation but will not make effect to humans .

I think the primary factor is the earths rotation. And it called the Coriolis effect.
The Coriolis Effect is responsible for this.
