The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.
No, the axis must be specified: torque = (distance from the axis) X (force).

cross: torque dot: work
Normally you use sine theta with the cross product and cos theta with the vector product, so that the cross product of parallel vectors is zero while the dot product of vectors at right angles is zero.
Cross product is a mathematics term when there is a binary operation on two vectors in three-dimensional space.

0 is a cross product of a vector itself
There are various physical situations in which the cross product naturally arises, for example in various relationships between electricity and magnetism. Another example is torque (the rotational equivalent of "force"): torque depends on the distance from the reference point and on the force. It also depends on the angle between the two (including the direction in the "distance"). Finally, the torque can conveniently be defined as having a "direction" that points in the axis of the resulting rotation (or angular acceleration). This gives you all the characteristics of a cross product.

at the cross meaning
because that is the def. of a cross-product!
Cross product is a mathematics term when there is a binary operation on two vectors in three-dimensional space.
The cross product is created.
1. meaning of physical needs?
A dot product is a scalar product so it is a single number with only one component. A cross product or vector product is a vector which has three components like the original vectors.
