Thermal energy is added to a sample, its particles move ?

Answers

Yes, if the temperature increases, than that means the particles are moving faster. Temperature is the measure of movement of particles in an object or substance.

By thermal energy, you mean adding heat correct....? I'm not very good at this sort of thing, but I gave you what I have..

Plates move apart at ____ boundaries.a. convergent
c. divergent
b. stable
d. transform

Answers

The correct answer is C. divergent. Divergent boundaries are something like lines found between two tectonic plates. These constructive boundaries, or extensional boundaries, are formed and exist between two tectonic plates that move away from each other. Convergent would thus be where they meet. This is all according to the tectonic theory.

Plates move apart at divergent boundaries, which occur when two tectonic plates are moving away from each other.

Plates move apart at divergent boundaries. Divergent boundaries occur when two tectonic plates are moving away from each other. This movement creates a gap or rift between the plates where molten rock rises to fill the space, forming new crust. The best example of a divergent boundary is the Mid-Atlantic Ridge.

It has been hypothesized, and some studies have supported the conjecture,
that certain species of insects and birds are able to sense the direction of external

I don't think there is any such notion where human beings are concerned.
