The region of the upper kantle which lies beneath the lithosphere and it is believed to be involved in the movement of plate tectonics.
Asthenosphere
Plates have edges called
Plate Boundaries
It has a pH level below 7
Acid
It has pH level above 7
Base
Combination of acid and base
Salt
Sudden shaking of the ground that we feel when rock layers slip past one another to a new position
Earthquake
The fracture in the surface of the crust where the two blocks of rocks slip is called the ? Which shows indication of relative movement
Fault
Areas along which all shallow earthquakes occur. These zones are believed to have exhibited evidence of strong and frequent earthquakes in the past thousand of years and are likely to exhibit movements sometimes in the future.
Active faults
Are areas which had not displayed any seismic activity for more than thousands of years
Inactive faults
Study of rocks
Petrology
Process where action of force forms, the large scale deformation of Earth’s surface through the mechanisms of rock movements within the crust. A fault is one of the efffects of it
Diastrophism
Meaning of PHIVOLCS
Philippine Institute of Volcanology and Seismology
Meaning of NASA
National Aeronautics and Space Administration
Invented the Richter magnitude scale
Charles Richter
Invented the Modified Mercalli Scale
Giuseppe Mercalli
Fastest seismic waves because they are the first waves detected by the seismograph, and they can travel at greatest velocity penetrating the gases, fluid and solid rocks
Primary waves
Transverse waves that are also known as shear waves that follow the P waves and the second to arrive at seismic recording station and travel half the speed of P waves
Secondary waves
Last waves that arrive due to their lower frequency
Surface waves
Waves that move the ground horizontally only
Love waves
Shake the ground horizonatally and vertically
Rayleigh waves
Process of development of a tropical cyclone
Tropical clycogenesis
The process of mountain formation, especially by folding and faulting of the earth’s crust
Orogeny
Layer of the atmosphere where clouds are formed
Troposphere
Trough of low pressure and is the most common mechanism that causes typhoons
Monsoon trough
