What is an example of a geological event?
Tsunami
Earthquake
Volcano Erupting
All of these answers are geological events.
How are tsunamis formed?
The ocean is heated by the Sun and expands the water.
An underwater disruption such as an earthquake.
Something large forcing the water onto shore.
Unusual tides
What is the most common cause of an earthquake?
Unusual movement of the Earth's tectonic plates.
Volcanoes erupting shake the Earth's surface.
Cracks in the Earth's surface (called fault lines) move and break under stress casuing vibrations.
Tsunamis
What is drought?
An area that typically does not receive much rainfall.
An area receiving an unusually low amount of rainfall for a long period of time.
When it rains a lot.
When farmers run out of water.
What should you do if you feel an earthquake starting to happen?
Stay put.
Run outside into open area, like the school oval.
Drop to the ground and hide under the nearest table.
Use an elevator to get out because it is fastest.
Which is NOT a part of a volcano?
Nitrogen
Magma
Lava
Ash
Crater
Where is an earthquake most likely to happen?
Near the ocean
Along the edge of tectonic plates
Near the equator
What is the Richter scale?
It shows the temperature of the ocean.
It measures the pressure of a volcano.
It measures the strength of an earthquake.
It measures how rich somebody is.
Cyclones happen in the tropical regions of Australia.
True
False
When can a volcano be classified as extinct?
When the volcano is cut off from its magma supply.
It has become cold on the inside.
The top of the volcano is sealed over.
Water from rainfall fills the inside of the volcano so it can no longer erupt.
What number does the Richter scale reach?
10
100
1000
2
Approximately how many of the Earth's volcanoes are found underwater?
80%
20%
All of them
Half of them
True or False? The Moon has volcanoes on it.
True - There are currently active volcanoes on the Moon.
True - There have been volcanoes on the Moon in the past, but there are no more active ones.
False - There have never been volcanoes on the moon.
What is it called when a volcano has not erupted recently but is expected to do so again?
Extinct
Active
Dormant
Asleep
What number does an earthquake have to reach on the Richter scale in order to be classified as major?
3
4
7
10
How many people were left homeless after The Great Chilean Earthquake? (The largest earthquake ever recorded with an instrumentally documented magnitude)
50
100 thousand
1 billion
2 million
What are the effects when a major earthquake happens?
Landslides
Tsunamis
Avalanches
Ground displacement (cracks in roads do to vibrations)
All of these effects can be caused by earthquakes.
How does a volcano erupt?
The magma inside a volcano rises to the surface, as it is lighter than the rock surrounding it.
A chemical reaction happens inside and it explodes out of the top.
It gets so hot within the volcano that the magma is pushed to the top.
What are the three main components of planet Earth's structure?
Crust, subpart and centre
Crust, mantle and core
Ground, subpart and core
Ground, mantle and centre
What do you call somebody that studies earthquakes?
Tectomologist
Seismologist
Earthquakologist
Earthomologist
Volcanologist
What do you call somebody that studies volcanoes?
Geologist
Volcanologist
Seismologist
Eruptologist
Is a tremor that is recorded as a 2 or below on the Richter scale considered to be an official earthquake?
Yes - all tremors that register on the scale are earthquakes.
No - it is too small to be considered a real earthquake.
How many micro earthquakes (less than 2 on the Richter scale) happen every day?
less than 5
8000
18
250
How frequently do meteroric earthquakes happen (this is a 10 on the Richter scale and the worst an earthquake can possibly be)?
There has only been one ever recorded.
1 every 50 years
1 every 20 years
There has never been a recorded meteoric earthquake.
The Mercalli scale measure the severity of what?
A volcanic eruption
An earthquake based on observation.
An earthquake using scientific measurements.
Tsunamis
What is the device used to measure the magnitude of earthquakes called?
Earthquake measurer
Sizeo-meter
Seismometer
Seismic waves
What are tectonic plates called when they are moving towards each other?
Divergent
Convergent
Transforming
What are tectonic plates called when they are moving apart from each other?
Divergent
Convergent
Transforming
What are tectonic plates called when they are sliding past each other?
Divergent
Convergent
Transforming
What type of tectonic plate movement causes the most amount of earthquakes? (Hint - The earthquakes are caused by a release of pressure built up by this movement)
Divergent
Convergent
Transforming
