Clay minerals are extremely fine-grained, sheet-like silicate minerals that form primarily through the chemical weathering and alteration of rocks and primary minerals. Although they are usually less than 2 micrometers (µm) in size, clay minerals have an enormous...

The continental crust is the thick, buoyant outer layer that forms Earth’s continents and continental shelves. Unlike the denser oceanic crust, continental crust is composed mainly of silica-rich (felsic to intermediate) rocks, making it less dense and capable...

Earth’s mantle is the thickest layer of the planet, extending from the base of the crust to the outer core at a depth of approximately 2,900 kilometers. It accounts for nearly 84% of Earth’s volume and about 67% of Earth’s mass. Although it is mostly...
