Earthquakes
What device is used to measure the magnitude of an earthquake?
Richter Scale
Define a converging boundary
A type of plate boundary where two tectonic plates move toward each other and collide.
What are the 3 types of impacts looked at in geography?
Hint: S, E, E
Social, Economic, and Environmental
Which human activity can increase the risk of erosion?
A. Replanting native vegetation
B. Building terraces
C. Deforestation
D. Installing windbreaks
C. Deforestation
What is Ms Vergara's favourite colour?
Blue
What does clustered mean in terms of earthquake epicentres?
A spatial pattern where epicentres are grouped closely together in a small area
What does subduction mean?
When one of the converging plates, usually the denser oceanic plate, is forced beneath the other plate into the mantle.
What is an example of a short-term social impact after an earthquake?
•death and injury •damage to private property and public infrastructure (i.e. water supply) •interruptions to infrastructure (e.g. transport, communication)
True or False:
Tectonic activity can create mountain ranges.
True
What year did Garden City open?
1971
What does linear mean in terms of earthquake epicentres?
A spatial pattern where epicentres are arranged in a straight line
Define a diverging boundary
A type of plate boundary where two tectonic plates move away from each other, creating new crust as magma rises from below the Earth's surface.
What is an example of an environmental long-term impact after an earthquake?
•destruction or loss of significant landmarks (human and natural)
•loss of habitat and wildlife
Which of the following is an example of a coastal landform?
A. Canyon
B. Headland
C. Valley
D. Plateau
Flyer is Ms Vergara's pet what?
Horse
Define an earthquake
An earthquake is the sudden shaking or movement of the Earth's surface caused by the release of energy from within the Earth's crust. This energy is usually released when tectonic plates shift or when stress builds up and is suddenly released along faults.
What are the three geographic terms that are used to explain the spatial distribution of earthquake epicentres?
Dispersed, linear, and clustered
What is an example of an economic short-term effect after an earthquake?
•destruction of businesses and interruption to trade
•possible increases in crime (e.g. looting)
Explain how tourism can impact natural landscapes positively and negatively
Positive impact: Tourism can raise awareness and provide funding for conservation.
Negative impact: It can lead to pollution, litter, trampling of vegetation, and overuse of resources.
What year did MacGregor State High School open?
1969
What is the measurement range on the Richter scale?
0 - 10 magnitude
Define a transform boundary and provide an example of one
A type of plate boundary where two tectonic plates slide past each other horizontally. This movement often causes earthquakes.
Example: The San Andreas Fault in California is a transform boundary between the Pacific Plate and the North American Plate.
Define short-term and long-term impacts
Short-term: Are immediate effects that happen during or right after an event like an earthquake. They usually affect people and services very quickly.
Long-term: Are effects that last weeks, months, or even years after the event. They can change how people live or how a country develops.
What are cardinal points?
The directions on a compass that lie between the four main cardinal points (North, East, South, West). They are Northeast (NE), Southeast (SE), Southwest (SW), and Northwest (NW)
Ms Vergara used to live around the corner from which celebrity when she lived in the USA?
Dwayne 'the rock' Johnson
