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 protects life on Earth from the Sunâs ultraviolet (UV) radiation. In the lower atmosphere (the troposphere) near the Earthâs surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions.At ground level, high concentrations of ozone are toxic to people and plants.zone protects life on Earth from the Sunâs ultraviolet (UV) radiation.
