Scientist use triangulation method to locate the epicentre of an earthquake from the data collected from Seismograph.
<u>Explanation:
</u>
The seismic data from three different location is collected to locate the intersect point as the epicentre point to be determined. Each earthquake is recorded in seismogram in different location.
A seismogram is the output from a graph called seismograph, which is used to determine the epicentre of an earthquake. There are two waves namely <em>P-waves or Primary waves and</em> <em>S-waves or secondary waves </em>that are considered while finding the epicentre of an earthquake.
With the seismogram, P-waves appears first before S-waves, since they travel faster through three states of matter. Thus, data from seismograph is used for locating “epicentre of an earthquake”.
Answer:
Global warming and climate change both share a relationship because they both have a negative effect on our planet Earth.
Answer:
Feldspar-clay
Quartz- No chemical change
Olivine- Limonite
Explanation:
When chemically weathered, some of the original minerals of granite change into different minerals.
Feldspar, for example, tends to hydrate and transform into a clay mineral.
Iron-rich minerals, like olivine, turn into limonite by chemical weathering. Quartz is considerably resistant to chemical weathering, so it´s the least susceptible to the chemical change.
