Earthquake
- has hypocenters and epicenters
- may be preceded by ground deformation
- measured by magnitude and intensity scales
- most frequent in alaska and volcanoes
Volcanoes
- cannot be predicted accurately
- measured by an explositivity index
- cause a visible fume or steam cloud or both
- often cause steam or gas to erupt in the atmosphere
- caused by molten rock erupting through earth’s surface

The smooth, but steady, increase in muscular tension produced by increasing the number of active motor units is called a recruitment.
Muscle tension is the force produced when a muscle contracts (or when sarcomeres shorten). The two primary forms of skeletal muscle contractions, isotonic contractions and isometric contractions, are produced when a muscle contracts against a load that is not moving.
- A load is transported as the length of the muscle varies during isotonic contractions, in which the tension in the muscle remains constant (shortens). Concentric and eccentric contractions are the two varieties of isotonic contractions.
- When a muscle contracts isometrically, the angle of a skeletal joint remains the same while tension is produced in the muscle. Sarcomeres shorten and muscles tense up during isometric contractions, but the load is not moved since the force generated is insufficient to overcome the resistance provided by the load.

Answer: Located within the thermosphere, the ionosphere is made of electrically charged gas particles (ionized). The ionosphere extends from 37 to 190 miles (60-300 km) above the earth's surface. It is divided into three regions or layers; the F-Region, E-Layer, and D-Layer.
