What is the scientific term for an earthquake?
Seism
Seismic event
Tectonic shift

What causes earthquakes?
The sudden release of energy from tectonic plates grinding against each other
Volcanic eruptions
Meteorite strikes
All of the above
Where are earthquakes most likely to occur?
Along plate boundaries
In the middle of oceans
On mountaintops
All of the above
What is the difference between the Richter scale and the Moment magnitude scale?
The Richter scale measures the amount of energy released in an earthquake, while the Moment magnitude scale measures the size of the earthquake rupture.
The Moment magnitude scale is more accurate than the Richter scale.
The Richter scale is only used for earthquakes in the United States, while the Moment magnitude scale is used for earthquakes worldwide.
Both scales are used to measure the magnitude of earthquakes, but the Richter scale is more commonly used.

(a) Seismograph
(b) Seismologists
(c) Richter scale
(d) All of these
Which one of the following statements is correct about wind?
(a) Wind is produced due to uneven heating on the earth by the sun
(b) Wind is produced due to even heating on the earth by the sun
(c) Sun does not effect wind on earth
(d) Both A and B
The upper layer of the earth is made of
(a) Core
(b) Tectonic plates
(c) Magma

In the atmosphere
What are the different types of cyclones?
Tropical cyclones
Extratropical cyclones
Mesocyclones
All of the above
What are the strongest winds in a cyclone?
