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).
The hole in the ozone layer happens because the ozone in the stratosphere is destroyed by chlorine and bromine from halogen atoms. These atoms come from man-made halocarbon refrigerator gases (chlorofluorocarbons [CFCs], freons and halons) which are emitted at ground level but move up into the ozone layer.zone depletion was observed to increase as emissions of halo-carbons increased. Ozone is a protective layer in the upper atmosphere. It is formed when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.
