Question 1
On the magnitude scale, each whole number up means the ground shaking (wave amplitude) is 10 times larger. How many times larger is the shaking in a magnitude 5 earthquake than in a magnitude 4?
Answer
Question 2
In the path from sedimentary to igneous rock, what comes straight after "buried deep and heated under pressure"?
- A. becomes metamorphic rock
- B. sedimentary rock
- C. magma cools to form igneous rock
- D. melts to form magma
Question 3
Earthquakes: which statement is NOT true?
- A. Each step up in magnitude releases about 32 times more energy.
- B. The focus of an earthquake is always on the surface.
- C. Undersea earthquakes can cause tsunamis.
- D. The point on the surface above an earthquake's origin is the epicentre.
Question 4
Which type of plate boundary is this: Iceland splitting slowly apart?
- A. divergent (moving apart)
- B. convergent (moving together)
- C. transform (sliding past)
Question 5
What turns sediment into sedimentary rock?
- A. compaction and cementation over a long time
- B. burning
- C. melting and cooling
- D. freezing
Question 6
Who first proposed that the continents drift?
- A. Charles Darwin
- B. Isaac Newton
- C. Galileo Galilei
- D. Alfred Wegener
Question 7
What drives the movement of tectonic plates?
- A. the Moon's gravity only
- B. ocean waves
- C. winds in the atmosphere
- D. convection currents and slab pull in the mantle
Question 8
Two plates move apart at about 5 cm per year. How far apart will they move in 1000000 years, in metres?
Answerm
Question 9
Plate tectonics: which statement is NOT true?
- A. Tectonic plates move several metres every day.
- B. Plates move a few centimetres each year.
- C. Mountains such as the Himalayas formed where plates collided.
- D. Scientists cannot yet predict exactly when an earthquake will happen.
Question 10
Why can scientists not predict the exact time of an earthquake?
- A. Earthquakes are random and have no causes
- B. Stress builds up unpredictably along faults, so only long-term probabilities can be given
- C. Earthquakes only happen at night
- D. Seismometers do not work
Question 11
Two plates move apart at about 4 cm per year. How far apart will they move in 100 000 years, in kilometres? (1 km = 100 000 cm)
Answerkm
Question 12
On the magnitude scale, each whole number up means the ground shaking (wave amplitude) is 10 times larger. How many times larger is the shaking in a magnitude 7 earthquake than in a magnitude 4?
Answer
Question 13
In the path from igneous to sedimentary rock, what comes straight after "igneous rock at the surface"?
- A. compaction and cementation form sedimentary rock
- B. weathering breaks it into pieces
- C. layers of sediment build up
- D. erosion carries the sediment to the sea
Question 14
Earthquakes: which statement is NOT true?
- A. The point on the surface above an earthquake's origin is the epicentre.
- B. Most earthquakes happen near plate boundaries.
- C. Earthquakes only happen in hot countries.
- D. Each step up in magnitude releases about 32 times more energy.
Question 15
Which type of plate boundary is this: Japan's volcanoes?
- A. divergent (moving apart)
- B. convergent (moving together)
- C. transform (sliding past)
