How are minerals identified for kids?
GeologyMineralogists use certain properties to identify a mineral: color, luster, hardness, cleavage, and streak. They may also use other tests, including how the mineral reacts to electricity or magnets. Minerals come in many different colors. How are mineral identified? Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak,

What is anticline fold?
GeologyHow are anticline folds formed? An anticline is a structural trap formed by the folding of rock strata into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline. What is anticline and syncline fold?
What is mechanical weathering in geology?
GeologyMechanical Weathering. Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. What is mechanical weathering short answer? Mechanical weathering is the process of breaking big
