Query about inclination in Earth's axis of rotation

Earth revolves around the Sun in a elliptical path, situated on one of the Sun's focal points. If Earth is considered as a large body with mass attracted towards the Sun's core causing its revolution ...

Would obliquity and precessional changes of Earth affect the accuracy of GPS-based measurement of tectonic movements?

The rate and direction of tectonic movements can be measured by comparing the coordinates of the same GPS receiver over time. The coordinates are obtained using trilateration. All materials I could ...

What would happen to the Subtropical Ridge/Horse latitudes and Polar front if the Earth was rotating 5% faster?

Would they move towards the Equator/Poles? Stay in the same place? What about if the Earth was rotating 10% slower? Is there a rotation speed for Earth which will lead to 4 wind belts instead of 3 ?
