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).
Ozone is made up of oxygen and is produced naturally in the atmosphere. As the presence of ozone gets reduced in the atmosphere, it causes the ozone layer to get thinner and thinner. The more ozone layer gets thin, the more big gets the size of ozone hole.
