Properties of Earth

The escape velocity of Earth (11.186 km/s) is the speed at which a free object must travel to escape into space from the planet’s gravitational pull.

Because the Earth is tilted on its axis, it’s why we have seasons. When Earth receives more sunlight on one side, it’s summer. And vice versa for winter.

As the Earth spins, the sun always shines on one side which gives it sunlight. When you’re facing the sun, it’s daytime. But when you’re not, it’s night.
