Your two adrenal glands are small, triangular-shaped endocrine glands located on the top of each kidney. Each adrenal gland is approximately 3 inches wide, and a half inch high. Each gland is divided into an outer cortex and an inner medulla. The cortex and medulla of the adrenal gland secrete different hormones.
The Causes of Ozone Depletion. Scientific evidence indicates that stratospheric ozone is being destroyed by a group of manufactured chemicals, containing chlorine and/or bromine. These chemicals are called ozone-depleting substances (ODS).
Causes. The main cause of Ozone Depletion are CFCs. CFC's drift in the environment until they reach the stratosphere. The UV radiation splits the chlorine from CFC's which attracts one of the three ozone atoms and destroys the ozone into ordinary oxygen.CFC's were ordinarilly used to replace the ammonia and its effects.he UV radiation splits the chlorine from CFC's which attracts one of the three ozone atoms and destroys the ozone into ordinary oxygen.
