Contact metamorphism can occur in this scenario.
Limestone is not formed from magma; it is a common sedimentary rock. However it may be worth noting that there is a rare form of igneous rock known as Carbonatite which is formed predominately from carbonate minerals and may be confused with Marble, however it is never described as Limestone. Please see the related link.

There is a vinegar test for limestone where if the vinegar bubbles on the rock it's a limestone
Mostly limestone and/or dolomite.
Marble is one.
It depends on what kind of rock they are made of. Cliffs formed of igneous rock generally do not contain carbonates. Cliffs that have some limestone, marble, or dolomite do contain carbonates.
It is Limestone Gypsum Coal Dolomite Halite Sandstone Conglomerate Shale

karst topography will contain mostly easily erodable bedrock, such as limestone and dolomite.
