Ozone (O3 ) is a made with three oxygen atoms; it is very unstable and has a short lifetime. At room Temperature and pressure has acrid odour and no colour, although at high concentration levels can turn Into blue. At high concentrations can be toxic and can cause death. It s not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight. VOC + NOx + sunlight tropospheric O3Particulate Matter (PM) "Particulate matter," also known as particle pollution or PM, is a complex mixture of extremely small Particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic...

WATER IN THE OCEANS
- SALT WATER: oceans and seas cover 71%of the earth´s surface . Most of the water on the planet is salt water. Rivers and rain carry rocks and minerals to oceans and seas ; this makes thm saline. Not all seawater hast the same salinity. Water in landlocked seas and in warmer latitudes is usually saltier, because the heat causes more evaporation than in open and cold seas.
- WATER IN MOVEMENT: Seawater is constantly moving because of the movement of curents, tides and waves. This movement erodes and shapes coastlines. Ocean currents are like big rivers moving within the oceans. The water in these currents does not mix with the rest of the sea because it has a different temperature or salinity. Currents can be warm or
Cycle : the natural sequence through
Which water passes into the atmosphere as water vapor, precipitates to earth in
Liquid or solid form, and ultimately returns to the atmosphere through
Sequence Of the water cycle proces :
Evaporation : water molecules in liquid state escapes into the air as Water vapor. /
Condensation: molecules Of water vapor in the air become liquid water. / Precipitation: any from of water that falls from clouds and Reaches Eath’s surface. /
Collection: This is when water runs off slopes.
Info: hydrological cycle: pathway of Water from the atmosphere to Earth’s surface, bellow ground and back. / Biogeochemical cycle: movement of A chemical through the biological and geological, or living and nonliving,... Continue reading "Air law" »
Climate refers to the typical weather that a place experiences over many years. Different parts of the world can be described as havinga dry, wet, hot or cold climates.
