It's a compound. Only two things are mixed to make it.
Niether. Volcanic rock is a mixture.
Sulfur is an elemental mineral, not a rock.
Silver is a metal element that is typically found in nature as a mineral within igneous and hydrothermal veins, rather than being a sedimentary rock component. It is primarily associated with volcanic and magmatic processes.
Granite is neither, it is a mixture. You can see grains of different minerals in it.

There is not enough information given to unambiguously answer the question.A "pebble" is a small piece of rock. What KIND of rock? It matters. Is it a brimstone pebble? Then it's an element. Is it a limestone pebble? Then it's a compound. Is it a granite pebble? Then it's a mixture.
Rock is not a compound or an element. Rocks are made up of minerals, which are compounds or mixtures of elements. Minerals are naturally occurring inorganic substances with a specific chemical composition and atomic structure.
Pumice is neither an element nor a compound. It is a type of volcanic rock that is made up of various minerals and volcanic glass.
Chemical formula for limestone is CaCO3. It is an inorganic compound.
how can a rock be an element?? then what is it chemical symbol? it is a heterogeneous mixture composed of various homogeneous mixtures. http://en.wikipedia.org/wiki/Rock_(geology)#Rock_classification
mixture of rock particle and salt

Feldspar is a mineral compound, not an element. It is a group of rock-forming tectosilicate minerals that make up about 60% of the Earth's crust. It is composed of aluminum, silica, and other elements like potassium, sodium, or calcium.
