What is geological risk?
It is the probability of human or material damage in an area as a result of geological processes.
What is an igneous rock?
A rock formed by the solidification of magma.
What is a sedimentary rock?
A rock formed by compacted and cemented sediment.
What is a metamorphic rock?
A rock formed from the transformation of other rocks due to high pressure or temperature.
The __________ is the continuous transformation of rocks through geological processes
Rock Cycle
What is seismic risk?
The risk of damage caused by earthquakes and vibrations in the Earth's crust.
How are igneous rocks formed?
From magma inside the Earth's crust that cools and solidifies.
How are sedimentary rocks formed?
From eroded material that is compacted and cemented over time.
How are metamorphic rocks formed?
Through heat and pressure acting on existing rocks.
What type of geological process creates igneous rocks—endogenous or exogenous?
Endogenouss
True or False: Sedimentary rocks are formed deep underground by magma.
False
True or False: Volcanic risk only includes the damage from lava during eruptions.
False. It also includes gases and indirect effects like earthquakes or tsunamis.
True or False: Seismic risk involves the vibrations of the Earth’s surface.
True
Name one indirect danger caused by a volcanic eruption.
Earthquakes, tsunamis, or landslides.
What does seismic risk depend on? (Name one factor)
frequency and violence of earthquakes, or the population at risk.
What kind of geological processes cause volcanic and seismic risks?
Endogenous processes
