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.

Yes because the cool air from a near by water source migrates toward the land to take the place of the hot air rising while the air over an area of water would be warmer because it is absorbing solar energy from the sun

c. Vietnam
Explanation:
Vietnam is a notably elongated country with a long coastline provides it with easy to access marine resources
Density, because the core is made of metals like iron and nickel
Well right now there are issues such as unemployment, government corruption, crime, access of clean water, and energy shortages.
In the future there could be issues such as lack of better healthcare treatments and equipment and better education.
