Answer:
Stalagmites
Sinkholes
Stalacites
Explanation:
These features are created because the ground water dissolves solid rocks and move the solid rocks, dissolve solutions beneath the ground water gradually and therefore enlarging the cracks, which eventually form a cave. Ground water carries minerals which are then deposited and can form stalagmites or stalactites. If a stalactite and stalagmite combine together, they usually form a column.

The sign of ΔSsys for diffusion of perfume vapors through the room is positive.
The measure of disorderliness or randomness of a thermodynamic system is known as entropy. No energy in the universe is completely transferred into work done and that portion of energy increases the randomness of the system.
ΔS is positive when entropy is increases and vice versa. Whenever the randomness of a particular system increase, entropy increases and ΔS becomes positive.
When the perfume vapors diffuse through a room its volume expands which results in increase of the randomness due to the motion of the molecules and hence the sign of ΔSsys becomes positive.
