Anearthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault.
or
An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves.
Earthquakes are accordingly measured with a seismometer, commonly known as a seismograph.
The magnitude of an earthquake is conventionally reported using the Richter scale or a related Moment scale
An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground.
The strain becomes so great that rocks give way by breaking and sliding along fault planes.
Earthquakes may occur naturally or as a result of human activities.
Smaller earthquakes can also be caused by volcanic activity, landslides, mine blasts, and nuclear experiments.
Answer:
When the propagation of an infectious disease gets reduced, people stop getting their children or themselves getting vaccinated for the infectious disease.
But what we forget is somebody out there might be an asymptomatic carrier of the disease and can spread the disease. As a result, if many people are not vaccinated for the particular disease, then there might be an outbreak of the infectious disease again and it can be deadly.
Photorespiration is detrimental for a plant because no glucose is produced.
Carbohydrates: glucose (monosaccharides)
Lipids: fatty acids
Nucleic acid: nueclotides
Proteins: amino acids

Minerals are also needed for the body although this should be taken in a very controlled amounts only.
Minerals and vitamins combined form the micro-nutrients of the body.
With micronutrients, only relatively little amount of nutrients is required to improve health. They are usually in milligram and microgram amounts and are enough to sustain to the metabolism and growth supplication. On the other hand, macronutrients are those that need large portions and quantities such as carbohydrates, fats and proteins. We need more of these to be converted to energy for movement and muscle growth. </span>
