1. The hypothesis that explains the release of energy during an earthquake is called the ____.
Richter hypothesis
moment magnitude hypothesis
vibration hypothesis
elastic rebound hypothesis

2. Most earthquakes are produced by the rapid release of which kind of energy stored in rock subjected to great forces?
chemical
thermal
elastic
mechanical

Elastic Rebound theory was the first theory to explain earthquakes. It says that most earthquakes are caused by the sudden release of energy that was stored. Elastic rebound theory is referred to as the accumulation and sudden release of strain and stress.

Elastic Energy is stored potential mechanical energy. It occurs in objects that are compressed and stressed. It is this energy that is suddenly released by the slabs of Earth's crust that results in an earthquake.

(1)The hypothesis that explains the release of energy during an earthquake is called the elastic rebound hypothesis

(2)Most earthquakes are produced by the rapid release ofelastic energy stored in rock.

Further Explanations:

1). Elastic rebound theory is a geological theory that explains the process of release of energy during an earthquake. During the distortion of the Earth's Crust, the alternate sides of the Earth's crust suffer a shear stress and it continues until the internal rigidity exceeds. The fault separates along a rapture calls fault line and the sudden movement releases a mass-energy that divides the plates into two halves. The energy released during this process is known as Seismic Wave.

2). The Seismic theory supports Reid's theory that concludes that the elastic rebound energy stored between the faults in the rocks is responsible for the occurrence of earthquakes. The energy stored is released partly in the form of heat and partly as seismic waves.
