Natural hazards Flashcards
What are tropical storms?
Tropical storms are violent, rotating storms that form in tropical region
List the 4 types of plate boundaries
Constructive
Destructive
Conservative
Collision
Name the 4 layers of planet Earth
Crust, mantle, inner core, outer core
State the 2 types of crust
Contintental
Oceanic
What is the state of Oceanic crust?
Oceanic: denser, thinner, heavier, newer rock
What is the state of Continental crust?
Continental: less dense, thick, lighter, older rock
What are Destructive plate boundries
Destructive plate boundaries are when two continental plates move
towards each other.
Which plate boundry is Haiti on?
Haiti is on a conservative plate boundary
What direction do Tropical storms move from?
East to West
At what type of plate boundary are the Himalayas formed?
The Himalayas are formed at a collision plate boundary
The area around the Pacific Ocean which experiences most
of the world’s earthquakes and volcanoes is called what?
Ring of Fire
State the type of plate boundary that formed the Mid
Atlantic Ridge.
Divergent/constructive
Name the theory about why tectonic plates move
Convection currents
Define Plate boundary
The place where 2 tectonic plates meet
Define Tectonic Hazard
A tectonic event which has the potential to damage life and property
Where can magma be
found?
The mantle
What are Tropical storms also called?
Hurricanes and cyclones
How do Tropical storms form?
They form in warm, deep oceans. When hit land they cause a lot of damage to infastructure
Name a real example of a constructive plate boundary
Mid-Atlantic Ridge
What hazards are found at destructive plate boundaries?
Volcanoes and Earthquakes
How do we measure earthquakes?
Richter scale
