A shortage of food that results in widespread hunger is called famine.
Frost wedging occurs because rocks becomes brittle when they freeze and water occupies more volume than ice.
Frost weathering is a collective term for several mechanical weathering processes triggered via stresses created by using the freezing of water into ice. The term serves as an umbrella term for a ramification of techniques which include frost shattering, frost wedging and cryofracturing.
Frost wedging takes place while water filling a crack freezes and expands (because it freezes, water expands 8 to 11% in volume over liquid water). The expanding ice imparts a extremely good amount of pressure against the rock (as plenty as 30,000 kilos/rectangular inch) and wedges open the crack.
Frost wedging takes place in locations which have the right temperatures to freeze water after which soften water. This normally happens in polar areas and mid latitude mountains wherein daylight can soften water throughout the day and refreeze overnight when temperatures drop.

Answer:
The thermocline is a layer in the ocean that represents:
<u> Density change due to temperature.</u>
Explanation:
A thermocline is a thin distinctive layer in a large body of fluid which is exactly located between warmer mixed water at the top of ocean surface and cooler deep water at the bottom of ocean surface. Salinity is defined as the total amount of salt dissolved in water.
The water in the ocean or sea forms into layers according to density. Water with high density sinks at the bottom while water with low density sits on the top. And the density of water changes with salinity and temperature. Higher salinity leads to higher density, and the water changes rapidly with depth.
