An edge dislocation of atoms experience tensil, shear and compressive
strains. Moreover, tensile strain produce a direct stresses and compressive
strain
produce in a body when two equal and opposite forces try to compress the body.
Meanwhile, shear strain is produce under a shear stress where the body displace
transversely from its original position.
As long as there's a FORCE applied on an object, and the object MOVES. it's work.
1. Force
2. Distance
That's all you need for work.

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.

Where does it occur?</span> These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best. Chemical weathering (especially hydrolysis and oxidation) is the first stage in the production of soils.
How does it occur? There are different types of chemical weathering, the most important are:
Solution - removal of rock in solution by acidic rainwater. In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation).
Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts.
Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.
I believe the correct answer is that <span>The genetic variation between humans and orangutans is the greatest.
We cannot say that there is no genetic variation at all, because there obviously is - we are not the same as the other three apes, even though we have a common ancestor. Also, we cannot say that we are completely the same, because there are obvious differences. And finally, we didn't originate from those three animals, but rather all of us come from the same organism.
