Ozone depletion refers to the decline of ozone gas in the Earth's atmosphere. This decline of ozone gas means large amounts of ultraviolet B radiation reaches the Earth's surface.
Ozone gas is a highly reactive gas that sits high up in the Earth's atmosphere. It shields the Earth's surface from dangerous ultraviolet B radiation that comes from the sun. Many attribute the depletion of ozone gas to high amounts of pollution that break down gas molecules. Ultraviolet B radiation has been linked to skin cancer in humans and has many other negative effects to different organisms, making the depletion of the ozone layer a pressing environmental and public health issue.Learn More
Wind is caused by a difference in air pressure. Air pressure changes develop due to heat absorption and are at their largest during the day. Wind speeds are determined by the rate of change in pressure between atmospheric areas.Full Answer >
The lithosphere on earth includes the rocky outer shell of the planet, the upper layer of mantle, and the crust. This layer, broken up into sections or tectonic plates, moves constantly and is responsible for the geological activity on earth. The lithosphere is about 60 miles deep in most places.Full Answer >
The simple carbon cycle can be broken down into three main processes: photosynthesis, respiration and combustion. These processes combine to recycle carbon in the atmosphere and synthesize new carbon sources.Full Answer >
According to the Environmental Protection Agency, chlorofluorocarbons (CFCs) and other complex chemicals make their way into the upper reaches of the stratosphere where they decay and release chlorine and bromine atoms that destroy ozone. The chemical reactions caused by these substances break apart the ozone atom, removing its protective capacity and increasing the amount of ultraviolet radiation that can pass through the Earth's atmosphere.Full Answer >
