IMPACTS OF OZONE Introduction Ozone is a gas that occurs naturally in our atmosphere. Most of it is concentrated in the ozone layer[->0]‚ a region located in the stratosphere several miles above the surface of the Earth. Although ozone represents only a small fraction of the gas present in the atmosphere‚ it plays a vital role by shielding humans and other life from harmful ultraviolet light from the Sun. Human activities in the last several decades have produced chemicals‚ such as chlorofluorocarbons

1. What are the causes of skin cancer? Exposure to abnormally high frequencies of light can potentially alter the DNA of a cell and turn it cancerous‚ the resulting cancerous cells are known as skin cancer. The most common cause is ultraviolet light emitted by the sun although it has been known to be caused by tanning booths‚ unusually high levels of x-rays‚ exposure to some chemicals and in rare cases the abnormal genes that cause skin cancer can be inherited by children from their parents.

geographic distribution of this characteristic that Mathiasen and Daugherty (2008) documented. What do they think this distribution tells us? Mathiasen and Daughtery documented the percent infection of different mistletoes on fir trees. Located south of latitude 44°N‚ red firs and trees that share a resemblance to noble fir were completely immune to Pacific silver fir dwarf mistletoe; however‚ trees also resembling noble fir north of 44°N were drastically parasitized by the mistletoe. Additionally‚ mountain

Though they are located in similar latitudes of the planet‚ the previously mentioned aspects affect their water budget in different and compounding ways. As classified by the Koppen Letter Code System‚ Berkeley falls in the Csa category‚ which is a mild‚ mid-latitude Mediterranean climate (Hess‚ 2013). These climates are referred to as dry summer subtropical‚ but are more generally described as Mediterranean

conditions of these variables in a given region. A region’s climate is generated by the climate system‚ which has five components: atmosphere‚ hydrosphere‚ cryosphere‚ land surface‚ and biosphere.[1] The climate of a location is affected by its latitude‚ terrain‚ and altitude‚ as well as nearby water bodies and their currents. Climates can be classified according to the average and the typical ranges of different variables‚ most commonly temperature and precipitation. The most commonly used classification

receiving the Sun’s direct rays is the equator. Here‚ air is heated and rises‚ leaving low pressure areas behind. Moving to about thirty degrees north and south of the equator‚ the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator‚ most of the cooling sinking air moves back to the equator. The rest of the air flows toward the poles. The air movements toward the equator are called trade winds- warm‚ steady breezes that blow almost continuously. The Coriolis

at the polar region while it is zero at the equator region. It was observed that Hurricanes are not formed around 5 degree latitude area away from the equator. Hurricanes are known to be formed with the help of Coriolis acceleration which keeps them rotating. The Coriolis acceleration is influenced by the sine of the latitude at that region. If it is at equator‚ the latitude is zero degrees and hence sine of it is zero at the equator region. So‚ there is no possibility for the Hurricanes to be generated

The Earth as a Rotating Planet. What is Geography- writing about the earth. 1. Much more than place names and locations. 2. The study of spatial variation. 3. How and Why things differ from place to place. On the surface of the earth. 4. How observable spatial patterns evolved through time. 5. Focus on the interaction of people and social groups with their environment 6. Geography is about space and the content of space. Geographers try to answer three questions

Tundra climate is usually found between the 60-75 degree latitude lines. Tundra climate is mainly found along the coast of the Arctic Ocean. Tundra is a transition climate between Ice Cap and Subarctic‚ similar to Semiarid being a transition between Arid and more humid climate. Tundra climate areas experience a very harsh winter and a cool summer. During the summer‚ much of the snow and ice melts and forms soggy marshes and bogs. However‚ some of the deeper parts of the soil stays frozen even
