It is an imaginary line parallel to the equator.  Our planet is divided into three climatic zone which are tropical, temperate and polar zone.  Tropical countries near the equator experience high temperature.  Example of a tropical country is the Philippines that experience high temperature.  Example of a tropical country is the Philippines that experience high temperature. Latitude Temperate zones are located in the middle latitudes. Countries under temperate zone experience moderate heat temperature and experience the 4 seasons. Countries under temperate zone, such as Canada, Japan and Australia experience this kind of occurrence. Countries under temperate zone, such as Canada, Japan and Australia experience this kind of occurrence.  Polar Zone Polar zones receives less to no sunlight because it is away to far from the sun because of latitude.  Polar Zone Countries such as Greenland and Antarctica receives less no to sunlight.  Polar Zone Countries such as Greenland and Antarctica receives less no to sunlight.  Remember! As the latitude increases, temperature decreases.  Another Factor that affects the weather is Proximity to Large Bodies of Water (Distance from the Sea).  Day time Soil absorbs heat faster than water, and soil releases heat faster compared to water. Places that are near the oceans have moderate climate as the body of water regulates it.  Night time At night, soils cools down faster than water. Places that are far from the bodies of water have extreme climates. Wind  Wind Winds that originate from a warm area bring about warm temperature. Winds from a cool area cools the air of the place.  Proximity to Mountain Ranges Mountains influence precipitation in two ways: 1. Orographic effect 2. Rain shadow effect  Orographic effect Refers to the dynamics of air and precipitation on the windward slope. Moist air masses are pushed upward and condenses as rain clouds. When clouds are saturated, precipitation occur.  Rain Shadow Rain shadow effect occurs on the leeward slope of the mountain, which is dry and less rain.  Causes of Climate Change And Global Warming Greenhouse Gases Are gaseous substances that absorb infrared radiation from the sun and trap heat sun’s heat in the Atmosphere.  Greenhouse Gases Carbon dioxide, methane, ozone and nitrous oxide and Chlorofluorocarbons (CFC)  Greenhouse Gases Much of the solar energy that reaches Earth is reflected back into the space, but some of this energy are trapped in the Atmosphere.  Carbon footprint Refers to the amount of carbon dioxide released into the atmosphere. Each person contributes to produce and emit carbon dioxide such as cooking, driving vehicles and burning materials.  Global Warming  Global Warming Refers to the long term average increase in global temperature. CLIMATE CHANGE IS A RESULT OF GLOBAL WARMING.  Global Warming Refers to the long term average increase in global temperature. CLIMATE CHANGE IS A RESULT OF GLOBAL WARMING.  ACTIVITIES THAT CONTRIBUTE TO GLOBAL WARMING Carbon dioxide emissions from burning gasoline Carbon dioxide is the main greenhouse gas emitted by motor vehicles. How to lessen Drive less by riding a bike instead of car Walk Carbon dioxide Emission from fossil fuel burning power plants.  97% of the electricity that power homes and offices is produced through burning coal, a fossil fuel. Burning coal and other fossil fuels releases large amounts of carbon dioxide release in the atmosphere. Increased use of chemical fertilizer in agriculture  Many farmers use chemical fertilizer that contain nitrogen. Microorganism in soil converts nitrogen in fertilizer into nitrous oxide (N20), a form of greenhouse gas. Deforestation Trees in forest take in Carbon dioxide and release oxygen during photosynthesis, reducing greenhouse gases in the atmosphere.  Impacts of Climate Change EL Niño  EL Niño El Niño which means “Christ the Child”. It refers to the irregular warming of the surface water in the Pacific that affects the trade winds over the equatorial region.  La Niña  La Niña which means “Little Girl”. It is a climate pattern that describes the cooling of surface-ocean waters along the tropical west coast. La Niña is considered to be the counterpart to El Niño. Poor water quality and Scarcity of Water Flood deposits wastes, silt, chemicals from agricultural pesticides, fertilizers and other pollutants to the bodies of water. Emergence of Climate- Sensitive Diseases and Illnesses. Heatstroke  When the body is exposed to extremely high temperature and does not get enough water for a prolonged period, it fails to regulate its temperature and suffers heatstroke.  Dengue virus-bearing mosquitos favor areas with warmer climates and more rainfall allow it to breed and multiply. Symptoms are high fever muscle and joint pain and weakness of the body. Waterborne Diseases  Leptospirosis This disease came from the urine of rats. It is cause by the bacterium Leptospira and it can affects both humans and animals.  Diarrhea This condition is caused by bacteria in contaminated food and water.
