A lever is a stiff structure that rotates around a fixed point. The fixed point around which a lever rotates is fulcrum.

1. The degrees are of different sizes. 2. The lower fixed point of Celsius is the freezing point of water, that of Fahrenheit is lower. Likewise the upper fixed point of Fahrenheit is quite low, but that of Celsius is higher, at the boiling point of water.
Yes, elements have fixed melting points; but some exceptions are with the elements having allotropes (as carbon, sulfur, phosphorous, etc.) - each allotrope has a specific melting point.
Reference point
The Earth orbits around the Sun is the simple answer, which is good enough for most people. However, a more accurate answer is that they both orbit the center of mass of the solar system. Because the Sun has nearly 99.9 percent of the mass of the solar system, the Earth orbits a point that's normally just outside the Sun's surface. So, the simple answer is fairly accurate.
Every point on Earth rotates from west to east. If you hang suspended over the north pole looking down at it, you see the Earth rotating counterclockwise (from right to left). If you hang suspended over the south pole looking down at it, you see the Earth rotating clockwise (from left to right).
The fulcrum
That is the Fulcrum.

A stiff rod that rotates around a pivot point is called a lever. It is a type of simple machine that is used to help move a heavy or firmly fixed load.
The fixed point of a lever is called the fulcrum. A lever is a beam connected by a hinge, or pivot, called a fulcrum. A lever is used to amplify the applied force.
The fulcrum is the fixed point or pivot around which a lever rotates or moves. It is the point where the input force is applied to the lever to create movement or lift an object.

needs to have a fixed point that it can rotate around
A lever pivots on a fulcrum.
Answer 1) They all move. But the moon moves around the earth which goes around the sun which is spinning.Answer 2) Both move. The sun rotates on a fixed point. The moon rotates arounds a fixed point and also rotates around the Earth.
The fulcrum is the pivot part of a lever.
