Except in the crust, the interior of the Earth cannot be studied by drilling holes to take samples. Instead, scientists map the interior by watching how seismic waves from earthquakes are bent, reflected, sped up, or delayed by the various layers.
TRUE
FALSE
There are ways to study the earth's interiors or layers. Which one of these options is incorrect?
Seismic waves detection
Lab Experiments
Drilling
Using satellites
The invention of the first seismoscope (now we know as seismograph) was in 132 AD by a Chinese inventor called Zhang (‘Chang’) Heng.
TRUE
FALSE
Seismograph comes from Greek words. These words means ‘to shake’ and ‘earthquake’ (seien and seismos) and ‘written, writing’ (graphos) or recording.
TRUE
FALSE
Which one of the statements below is INCORRECT
A seismograph creates the seismogram. A seismogram is a record of the seismic waves
The sensor part of a seismograph is called the seismometer.
A seismograph is an instrument that measures and records seismic waves that move through the earth when there is an earthquake
When there is an earthquake, a seismograph will make a record or draw a line only if the shake of the ground is strong.
Tick the statements below that you think it is relevant and correct (you can tick more than one or all of them )
Scientist use this drawing to
find the time the earthquake occurred
to find the location of the earthquake
to know how far below the earth’s surface the earthquake happened
know the amount of energy released by the earthquake
learn more about tectonic plates and the earth’s layers
People develop seismograph into Electromagnetic Seismographs in 1900s
TRUE
FALSE
Electromagnetic seismographs works when a coil is moved through a magnetic field whenever there is an earthquake.
TRUE
FALSE
The Richter magnitude scale is a scale of numbers used to tell the size of earthquakes. Charles Richter developed the Richter Scale in 2005
TRUE
FALSE
The highest and most destructive earthquake measured by using Richter Scales is 5 Richter scale.
TRUE
FALSE
