Plate Tectonics
This is the name of the theory that explains the movement of the Earth's lithospheric plates.
What is Plate Tectonics?
A sudden event that causes widespread destruction, loss of life, and environmental damage.
What is a disaster?
Molten rock that erupts from a volcano is called this.
What is lava?
A huge sea wave generated by underwater earthquakes or volcanic eruptions.
What is a tsunami?
This term describes the center of a hurricane, where the weather is calm.
What is the "eye"?
This type of plate boundary occurs when two plates move away from each other.
What is a divergent boundary?
A natural disaster that involves a rapidly moving mass of rock, soil, and debris down a slope.
What is a landslide?
A volcano that has not erupted in a long time but could become active again is classified as this.
What is dormant?
The point on the Earth's surface directly above an earthquake's focus.
What is the epicenter?
This scale is used to measure the strength of hurricanes, ranging from 1 to 5.
What is the Saffir-Simpson Scale?
The Himalayan Mountains were formed by the collision of these two types of plates.
What are continental plates?
A disaster caused by human actions, such as oil spills or nuclear accidents.
What is an anthropogenic disaster?
This type of lava is thick and slow-moving, often forming explosive eruptions.
What is acidic lava?
The most earthquake-prone country in the world.
What is Japan?
For a hurricane to form, the water temperature must be above this degree Celsius to provide enough energy for the storm.
What is 26.5°C (about 80°F)?
The process where one plate is forced under another at a convergent boundary.
What is subduction?
This weather-related hazard involves strong winds, heavy rainfall, and storm surges.
What is a hurricane/cyclone/typhoon?
A fast-moving, deadly cloud of hot gas, ash, and volcanic rock.
What is a pyroclastic flow?
These seismic waves cause the most damage during an earthquake.
What are surface waves?
In Tobago, this government agency is responsible for providing warnings and information during hurricane season to reduce the impact of storms.
What is the Trinidad and Tobago Meteorological Service?
his is the name of the supercontinent that existed around 300 million years ago.
What is Pangaea?
The scale used to measure the intensity of earthquakes.
What is the Richter scale?
The term for volcanic mudflows caused by melted snow and ash
What is a lahar?
This is the process in which saturated soil loses its strength due to earthquake shaking.
What is liquefaction?
These are the four stages of a hurricane, starting from a weak disturbance to a fully-formed hurricane.
What are Tropical disturbance, Tropical depression, Tropical storm, and Hurricane?
