Granite
Gneiss
Pumice
Basalt
Answer is Right!
Answer is Wrong!
The correct answer is (c), pumice. Pumice is a type of volcanic rock that is light and porous. It is formed when lava cools rapidly and traps gas bubbles. Granite, gneiss, and basalt are all types of igneous rocks that are formed when magma or lava cools and solidifies.
Granite is a coarse-grained igneous rock that is composed of quartz, feldspar, and mica. It is a common rock type in the Earth’s crust. Gneiss is a medium- to coarse-grained igneous rock that is composed of feldspar, quartz, and mica. It is formed when granite is subjected to heat and pressure. Basalt is a fine-grained igneous rock that is composed of plagioclase feldspar, pyroxene, and olivine. It is a common rock type on the Earth’s surface.
