Home Geology Fundamentals
Geology is the science that explores how the Earth was formed, how it changes, and what its physical materials reveal about the planet’s long and complex history. From the deep interior of the Earth to the landscapes we see on the surface, geology connects every process that shapes our environment. It explains earthquakes, volcanoes, mountain building, erosion, sedimentation, and the formation of rocks and minerals, giving us a complete picture of how our world works.

Weathering Types
Weathering is the combination of processes that breaking down of rocks, soil and minerals, eventually transforming into sediment. On the other hand, disintegration or alteration of the rock surface in its natural or original position through physical, chemical and biological processes induced or modified by wind, water and climate.

Fault and Types of Faults
Fault is a fracture or crack where two rock blocks slide past one to another. If this movement may occur rapidly, it can be causes earthquike or slowly, in the form of creep.Types of faults include strike-slip faults, normal faults, reverse faults, thrust faults, and oblique-slip faults.

Unconformities
An unconformity is contact between two rock units.Unconformities are typically buried erosional surfaces that can represent a break in the geologic record of hundreds of millions of years or more. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity. An expected age of layer or layers of rock is/are missing due to the erosion; and, some period in geologic time is not represented.
