Thee true statement is that Earthquake magnitude is based on ground motion recorded by a seismograph; intensity is based on the amount of damage produced.
<h3>How is the magnitude of an earthquake known by a seismograph?</h3>
The Richter magnitude of an earthquake is known to be seen through the use of the logarithm of the amplitude of waves as recorded by a seismographs.
The different Adjustments rates are included for the variation that exist between the distance from various seismographs and the epicenter of the earthquakes.

Answer:
Oxygen
Explanation:
The earth has been divided into three major categories crust, mantle, and core which are further segregated into sub-parts. Since the crust is the outermost layer of the shell, the outer crust of the earth consists of a combination of silicon and oxygen in the majority followed by some percentage of other metals as well. <u>The percentage of Oxygen includes nearly 50% i.e. 46.6% followed by 27.7% of Silicon and the other 25.3 % includes aluminum, iron, sodium, magnesium, etc</u>. Thus, '<u>oxygen</u>' is the correct answer.
geophysical phenomena is earth and its environment in space for example its when earthquakes, Tsunami, Volcanic activity, cyclone stuff sorta like that
hope that helps
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
