An earthquake refers to the sudden shaking of the earth, which can cause damage depending on the intensity and magnitude.
The magnitude and intensity are the two main characteristics of an earthquake.
Magnitude is defined as the amount of energy that is released during an earthquake. This magnitude is measured using a scale known as the 'Richter scale'. The Richter scale ranges from 1 to 10, where an earthquake of magnitude 10 is extremely destructive.
The intensity of an earthquake is defined as the amount of destruction that an earthquake can create. It is measured in terms of a scale which is known as the 'Mercalli Intensity Scale' that ranges from I to XII.
Photosynthesis and chemosynthesis are both processes by which organisms produce food; photosynthesis is powered by sunlight while chemosynthesis runs on chemical energy. ... Ecosystems depend upon the ability of some organisms to convert inorganic compounds into food that other organisms can then exploit (or eat!).
