C) landslides.
Explanation:
Landslides is not a way in which mountains are built on earth. It is a destructive process in nature that causes the slumping and wasting of land masses.
Landslide is a form of mass wasting and does no build masses.
Volcanoes helps to build mountains on the crust and this way, igneous rocks are formed.
Deposition process upbuilds to form sedimentary rocks.
Faulting is a can also be a constructive process that builds a mountain in the case of horsts and graben

Answer:
Where is the picture? Can't answer without it.
Answer:
Solvent will be lost as gas and not return into the vessel via condensation.
Explanation:
Reflux is a technique used in chemistry to boil a particular solvent and convert the gas formed back into liquid by condensation. This technique allows a solvent to be heated at a regulated temperature but for a prolonged period of time than it would normally take place.
The reflux procedure makes use of a reflux CONDENSER, which is an apparatus that allows vapour from the heating/boiling to flow back into the reaction vessel. The CONDENSER functions to prevent the loss of the SOLVENT as vapour by providing a cooling effect on the vapour.
Therefore, if a reaction was refluxed without a condenser, THE SOLVENT WILL BE LOST AS VAPOUR
This was because the experiment showed that a substance could emit radiation even while it was not exposed to light.
Answer : The change in entropy is 
Explanation :
Formula used :
where,
= change in entropy = ?
m = mass of water = 1.00 kg
= heat of vaporization of water = 
T = temperature = 
Now put all the given values in the above formula, we get:
Therefore, the change in entropy is
