If miners will dig into the Earth in search for precious rocks and minerals, in which layer would be their deepest possible exploration?
crust (5 - 100 km thick)
The recording of the ground shaking at the specific location of the instrument
seismogram
In which type of igneous rock do big crystals form?
intrusive igneous rock
Why do earthquakes occur?
Earthquakes occur due to the interaction of tectonic plates. Their movement generates huge amount of energy that make the ground shake.
These are natural substances composed of solid crystals of different minerals that have been fused together into a solid lump.
rocks
It refers to the point directly above the focus on Earth’s surface
epicenter
Type of scientific research that is also called "pure research"
basic research
It is a direct hazard that can cause secondary hazards.
groundshaking
What type of rock is granite?
igneous
Type of scientific research that applies basic research toward more practical endeavors, such as solving everyday problems.
applied research
What type of rock is marble?
metamorphic
State the difference between magma and lava
Magma is a molten rock that is underground while lava is a molten rock that breaks through the Earth's surface.
What are the two types of seismic waves?
body and surface
It is the main cause of destruction during an earthquake.

What is the full name of British physicist who first mathematically demonstrated the existence of rayleigh wave?
Lord Rayleigh
What are the two forms of surface waves
love and rayleigh

Type of wave that can travel through solid and fluid materials
primary wave
What type of rock is slate?
metamorphic
Does the oceanic crust sink beneath the continental crust at the subduction zone? Why or why not?
Yes, because oceanic crust has a greater density.
What do you call the solid inorganic substances of natural occurrence that form rocks?
minerals
What type of wave can travel through solid materials only?
secondary wave

seismometer
Give the 3 main types of scientific research based on where it is conducted.
laboratory research , library research, and field research
What type of rock is produced when an original rock is subjected to very high heat and pressure?
metamorphic rocks
Explain the process of rock cycle
weathering and erosion > transportation > deposition > compaction and cementation > metamorphism > rock melting
What type of convergent plate boundary is Sierra Madre?
