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.
Shale is neither an element nor a compound. Shale is a type of sedimentary rock that is made up of a mixture of minerals, organic matter, and other materials.

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.
mixture of rock particle and salt
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

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.
