10. which is not true about s waves?

Your answer would be D.

Explanation:

They change the volume of material by compression and expansion.

It is not true that S waves change the volume of material by compression and expansion.

Explanation:

S-waves are transverse seismic space waves (waves moving through the interior of the Earth). With S waves, particles vibrate in the material through which the wave moves (the medium) perpendicular to the way of movement of the wave. Shift occurs in the material, from which it can be deduced that S-waves can only move through elastic materials. S-waves therefore do not occur in liquids or gases.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
