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).
As explained above, the primary cause of ozone depletion is the presence of chlorine-containing source gases (primarily CFCs and related halocarbons). In the presence of UV light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction.ost of the ozone that is destroyed is in the lower stratosphere, in contrast to the much smaller ozone depletion through homogeneous gas phase reactions, which occurs primarily in the upper stratosphere.
