…how fast the Earth travels in its orbit around the Sun?
Earth speeds along at an average of 107,000 km/h. That’s 29.8 km/s. Because you are on Earth, you are travelling at the same speed.

…why the Earth is always tilted in mounted globes?
Earth’s axis – the imaginary line around which Earth rotates – tilts about 23.5 degrees from an upright position relative to the Sun. Globes show this tilt so that you can picture the way the Earth spins as it revolves around the sun.

...why summer days are longer than winter days?
The Earth is tilted in relation to the Sun. When the Northern Hemisphere of the Earth is tilted towards the Sun, the Sun's rays hit more directly. The more direct and therefore warmer. The tilt of the Earth also makes the Northern Hemisphere experience longer days during this time, and the Sun appears to pass higher in the sky. Six months later, Earth has moved halfway through the orbit and the Southern Hemishpere is tilted towards the Sun. This means it is summer in the Southern Hemisphere and winter in the Northern Hemishpere.
