  ROCK SALT
Correct Answer
I. CONGLOMERATE

Explanation
Conglomerate is a type of sedimentary rock composed of rounded fragments of different sizes and types of rock held together by a matrix of finer material. It is typically formed in high-energy environments such as riverbeds or beaches where the fragments are transported and deposited by water or wind. Conglomerate is characterized by its visible pebbles or cobbles within the rock and its coarse-grained texture.

Correct Answer
G. GNEISS

Explanation
Gneiss is the correct answer because it is a type of metamorphic rock that is characterized by its banded appearance and high degree of foliation. It is formed from the recrystallization of pre-existing rocks under high temperature and pressure conditions. Gneiss typically contains minerals such as quartz, feldspar, and mica, which contribute to its distinct texture and coloration. This rock type is commonly found in regions of mountain building and is often used as a decorative stone or in construction due to its durability and attractive appearance.

Explanation
Basalt is the correct answer because it is a type of igneous rock that is formed from the cooling and solidification of lava or magma. It is typically dark in color and has a fine-grained texture. Basalt is commonly found in volcanic regions and is known for its strength and durability. It often contains minerals such as pyroxene and olivine.

C. SLATE

Explanation
Slate is the correct answer because it is a type of rock that is formed from the metamorphism of shale or mudstone. It has a fine-grained texture and is often used as a roofing material or for making blackboards. Slate is characterized by its ability to be split into thin, smooth sheets, making it a popular choice for various construction and decorative purposes.

Correct Answer
B. LIMESTONE

Explanation
Limestone is the correct answer for identifying the rock in case E. Limestone is a sedimentary rock composed mainly of calcium carbonate. It is typically formed in marine environments through the accumulation and compaction of organic remains such as shells and coral. Limestone is often light in color and can have various textures, ranging from fine-grained to coarse-grained. It is commonly used as a building material and in the production of cement.

D. QUARTZITE

Explanation
Quartzite is the correct answer because it is a type of metamorphic rock that is formed from sandstone. It is known for its hardness and durability, making it a popular choice for countertops and other construction materials. Quartzite is composed primarily of quartz grains that have been recrystallized under high heat and pressure. It often has a white or light gray color, but can also be found in shades of pink, red, or yellow.

Explanation
Marble is the correct answer because it is a type of metamorphic rock that is formed from limestone. It is known for its smooth and polished appearance, and is often used in sculpture and architecture. Marble is composed of recrystallized carbonate minerals, usually calcite or dolomite, and can come in a variety of colors and patterns.

E. GRANITE

Explanation
Granite is a type of rock that is commonly identified by its coarse-grained texture and speckled appearance. It is composed mainly of quartz, feldspar, and mica minerals. Granite is an igneous rock that forms from the slow cooling and solidification of magma deep within the Earth's crust. It is widely used in construction and as a decorative stone due to its durability and attractive appearance.

Explanation
Sandstone is a type of sedimentary rock that is composed of sand-sized grains of mineral, rock, or organic material. It is typically formed in environments such as beaches, deserts, and riverbeds where there is a large amount of sand deposition and compaction over time. Sandstone is known for its grainy texture and can come in a variety of colors, including tan, brown, red, and gray. It is a common building material and is also used in the construction of statues, monuments, and decorative items.
