Gravity..
Sun's Gravitational force.
Because the moon keep going round and round the Earth
Earth is similar to a merry-go-round in that both rotate around a central axis. Just as a merry-go-round spins, creating a circular motion, Earth rotates on its axis, resulting in day and night cycles. Additionally, both exhibit centrifugal force: on a merry-go-round, riders feel pushed outward, while on Earth, this force slightly counteracts gravity, causing a slight bulge at the equator. Both also require a stable central point to maintain their motion.
Wind force or wind energy is the force that makes a windmill go round. When the wind blows, it causes the blades of the windmill to spin, converting the kinetic energy of the wind into mechanical energy to drive the rotor and generate electricity.
Pythagoras stated the earth was round
Sun's Gravitational force.
Because of gravity. Gravity is a force that pulls everything towards the center of the Earth. This force keeps people on the ground even though the Earth is round. Hope this helps!

Gravity and Inertia
an orbit is the circular movement of a planet going round the sun, or a moon going round a planet. Gravitaional force is what creates the orbit.

No, it is the mass of the Earth that keeps it spinning steadily. The Earth is in free fall going round the Sun so it feels no force on it. The force is exactly balanced by acceleration towards the Sun. But because the Earth is big and the Sun relatively close, the point of Earth nearest the Sun (where the Sun is overhead) has a little more force than the centre, and twice as much as at the opposite point, and the difference is called a tidal force.
The ancient Greeks had worked out that the world was round by looking at the shadow that the Earth makes on the moon. Colombus knew it was round.
That's the mutual gravitational attraction between the sun and the earth.
The earth's gravity field makes everything push into the earth like a bubble arround the planet. This makes it seem like the earth is flat.
