Physical Weathering Definition, Processes and Types ...

When the temperature of the rock rises, the rock expands and when the temperature of the rocks decreases, the rock contracts. Because the outer surface is more exposed than the inner surface, there is uneven contraction and expansion of the rock's constituent minerals.

Weathering of Rocks: Physical and Chemical | Geology

ADVERTISEMENTS: After reading this article you will learn about the physical and chemical weathering of rocks. Mechanical Weathering or Physical Weathering: Mechanical or physical weathering refers to changes involving form only. Due to this type of weathering large solid masses may break into loose fragments varying in size and shape but maintaining their original composition.

What is a spiral fracture? Causes and treatment

Aug 30, 2017· Spiral fractures are usually serious injuries and carry the risk of complications. When long bones are broken on an angle, they often separate into two parts that do not align and have rough, uneven edges. This fracture can make it difficult to put the bone back together.

MINERALS AND ROCKS

MINERALS AND ROCKS Mineral is defined as a naturally occuring, solid crystalline substance, generally inorganic with a specific chemical composition. Minerals are homogenous; they cannot be divided mechanically into smaller components. Minerals are the building blocks of few rocks.

Discovering the Different Hardness of Minerals

Fracture is irregular breakage. For example, quartz has a conchoidal fracture; it breaks along hollowed and rounded, uneven surfaces. Cleavage is a regular breakage that follows the atomic structure of a mineral. Cleavage results in smooth, planar surfaces. Different minerals may have one, two, three, four, or .

Chlorite is a member of the mica group of minerals (sheet silicates), like biotite and muscovite. Chlorite is widespread in low grade metamorphic rocks such as slate and schist, in sedimentary rocks, and as a weathering product of any rocks that are low in silica (especially igneous rocks). Chemical composition (Fe, Mg, Al) 6(Si, Al) 4O 10(OH) 8.
