Explanation

The Earth moves around its axis once in 24 hours — this is called rotation.

While its motion around the Sun once in approximately 365 days is called a revolution.

(Note: You mentioned "356 days" — this appears to be a typo. The correct value is approximately 365.25 days.)

Explanation

The Earth bulges at the equator and rotates, creating a centrifugal force that slightly reduces gravity there.

At the poles, this effect is minimal, so ‘g’ is stronger at the poles than at the equator.

Explanation

Geophysics is the science that studies the internal structure and physical properties of the Earth.

It includes the study of earthquakes, magnetic and gravitational fields, and Earth's interior layers.

Explanation

The cochlea is a spiral, snail-shaped structure in the inner ear responsible for converting sound vibrations into nerve signals.

It plays a key role in the sense of hearing.

Explanation
