The rocks in which argil (or clay) predominates, are called A. Siliceous rocks B. Argillaceous rocks C. Calcareous rocks D. Igneous rocks

Siliceous rocks
Argillaceous rocks
Calcareous rocks
Igneous rocks

The correct answer is: B. Argillaceous rocks.

Argillaceous rocks are sedimentary rocks that are composed mainly of clay minerals. Clay minerals are hydrous aluminum silicates that are formed by the weathering of feldspars and other minerals. Argillaceous rocks are typically soft and easily eroded. They are often used in the manufacture of ceramics and other products.

Siliceous rocks are sedimentary rocks that are composed mainly of silica. Silica is a chemical compound that is found in sand and quartz. Siliceous rocks are typically hard and durable. They are often used in the construction industry.

Calcareous rocks are sedimentary rocks that are composed mainly of calcium carbonate. Calcium carbonate is a chemical compound that is found in limestone and chalk.

Calcareous rocks are typically soft and easily eroded. They are often used in the manufacture of cement and other products.

Igneous rocks are

formed when magma or lava cools and solidifies. Magma is molten rock that is found beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface. Igneous rocks are typically hard and durable. They are often used in the construction industry.
