Question

Identify the FALSE statement. Silicates. . .

A. Have the silicon-oxygen tetrahedron as their structural unit
B. Are classified on the basis of how the tetrahedrons join and share oxygen atoms
C. Are a large category of minerals and include the common minerals and calcite dolomite
D. Are a major component of continental crust

Answer 1

The false statement is that silicates include calcite and dolomite, which are not silicates but carbonates. Silicates do have a tetrahedral structure, varied classification based on tetrahedra connections, and are a major part of the Earth's crust.

Step-by-step explanation:

The false statement is 'Silicates... C. Are a large category of minerals and include the common minerals and calcite dolomite.' This is false because calcite and dolomite are not silicates; they are carbonate minerals. Silicates are indeed the largest class of minerals, characterized by the silicon-oxygen tetrahedron as their fundamental building block. They are classified based on how these tetrahedra connect, sharing oxygen atoms in different configurations, and contribute significantly to the composition of the Earth's continental crust.
