100
They are built from particles and blobs of congealed lava ejected from a single vent.
What are Cinder Volcanoes?
100
the area above the focus of an earthquake
What is an epicentre
100
This is a standard scale to measure Earthquakes. This measures on the factor of 10.
What is the Richter Scale?
100
A device that is used to accurately record the motion of the ground during an Earthquake.
What is a Seismograph?
100
Results from relatively short, intense bursts of rainfall such as from severe storms.
What is flash flooding?
200
A gap can can be created by subduction of tectonic plates that shift when there is a "weak spot" in the Earth's crust, which then can lead to lava to travel through the fissure to the lava chamber.
What is a fissure?
200
When more heat escapes from your body than your body can produce.
What is Hypothermia?
200
A series of volcanoes which surround the Pacific, mainly on the Pacific Plate.
What is the Ring of Fire?
200
The Energy released by the Earthquake.
What is Magnitude?
200
A type of thunderstorm that is made up of many other storms. These can sometimes produce severe hail and wind.
What are multicellular thunderstorms?
300
These are a type of volcanoes that can be also known as stratovolcanoes. These are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8000 feet above their bases.
What are composite volcanoes?
300
Fast moving currents of hot gas and rock which travels downhill from a volcano, reaching speeds of 700km/h. The gas can reach temperatures of more than 1000 degrees C.
What is Pyroclastic Flow?
300
A volcano that is located near Vancouver. It is one of 4 volcanoes that surrounds Vancouver in America.
Where and what is Mount St Helens?
300
This is an Earthquake that can occur which has a magnitude of less than 5.
What is a Tremor?
300
Long-lived thunderstorms with strong, swirling winds rotation within their cores. These produce very large hailstorms, extreme wind gusts, powerful tornadoes and heavy rainfall.
What are Supercell Thunderstorms?
400
These are built mostly entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently, sloping cone of flat, domical shape, with a profile much like that of a warrior's shield.
What are shield volcanoes?
400
Chunks of lava blasted into the air which solidify before they reach the ground. They can be extremely large, measuring up to 5-6 metres in diameter and landing more than 500 metres from the volcanic vent.
What are volcanic bombs?
400
A volcano located in New Zealand that has had a history of volcanic hydrothermal eruptions in 2005, 2003, 2001, and 2000.
Where is Rotorua?
400
Boundaries that are mostly on ocean floors.
What are divergent boundaries?
400
A storm that produces highly frequent lightning strikes. These sometimes can be severe.
What is an electrical storm?
500
A mountainous landscape that is formed by tectonic plates that has a formed cone on the tip of the mountain. These can be classed as extinct, active or dormant (meaning to hibernate).
What is a volcano?
500
A large underground pool of molten rock sitting under the Earth's crust. These contents is less dense than the surrounding mantle and so it seeps up to the surface through cracks and flaws in the crust.
What is a magma chamber?
500
This is a way of measuring air pressure to predict if Australia is either going to be very wet, or very dry.
What is the Southern Oscillation Index?
500
Earthquakes that occur away from the plate boundaries.
What are intra-plate Earthquakes?
500
An Indonesian word describing mudflows and debris flows that originate from the slopes of a volcano.
