Which of the following natural occurrences would be most likely to have an impact on our global climate? A. B. C. D. An earthquake A tsunami A tornado A volcanic eruption MYP Unit Question: What should I wear today? Area of Interaction: Environment Learner Profile: Communicator Standard: Understand how the distribution of land and oceans affect climate and weather Learning Standard: I’m learning about climate because it is different from weather. Opening: Work Session: Climograph Closing: Study Jams - Clouds Climate Zones What’s the difference between weather and climate? Weather Weather is the condition of the atmosphere at a particular time. This condition includes temperature, humidity, precipitation, wind and visibility. Climate Climate is the average weather condition in an area over a long period of time. images of different climate zones Baffin Island Sun Photograph by John Dunn The midnight Arctic sun never strays from the horizon in this time-exposed shot of Nunavut's Baffin Island. Some parts of Nunavut endure 24 hours of light from late April until late August and 24 hours of darkness from late October until mid-February. In Brazil, which houses 30 percent of the remaining tropical rain forest on Earth, more than 50,000 square miles of rain forest were lost to deforestation between 2000 and 2005. The rain forest is nearly self-watering. Plants release water into the atmosphere through a process called transpiration. In the tropics, each canopy tree can release about 200 gallons (760 liters) of water each year. Grasslands are found where there is not enough regular rainfall to support the growth of a forest, but not so little as to form a desert. Tundras are among Earth's coldest, harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy and rainfall is scant. Deserts cover more than one fifth of the Earth's land, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. The Earth has three major climate zones. Each zone has a temperature range that relates to its latitude. In each of these zones, there are several types of climates because of the differences in the geography and the amount of precipitation. This creates different biomes, which are large regions characterized by specific climates, types of plants and animal communities. World Climates What affects climate? Latitude—the higher the latitude, the cooler the climate Prevailing winds—carry different amounts of moisture Uneven heating of land and water Ocean currents Hey! Mars has climate zones, too!
