Unit 1: The World
Physical Geography
![Page 2: Unit 1: The World Physical Geography. Weather Condition of the atmosphere at a particular place and time Climate-weather conditions a particular location.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649f145503460f94c299a8/html5/thumbnails/2.jpg)
Weather
• Condition of the atmosphere at a particular place and time
• Climate-weather conditions a particular location over a long period of time.
• Causes: water vapor, cloud cover, landforms, elevation, air movement

Weather Extremes
• Hurricanes/typhoons• Tornadoes• Blizzards• Droughts• Floods

World Climate Regions
• 5 large regions: tropical, dry, mid-latitude, high latitude, highland.
• Sub-regions exist too…

Sub-Regions
• Tropical Wet– Always hot– Sunny in the morning
but rain daily– Lots of rainfall: 80
inches a year– Central and South
America– Africa, Southwest Asia

Sub-Regions
• Tropical Wet and Dry– Rainy season in summer• Warmer temps
– Dry season in winter• Cooler temps
– Rainfall is less than in tropical wet
– Africa, South and Central America, parts of Asia

Sub-Regions
• Semiarid– Less than 20 inches of
rain a year– Summers are hot– Winters are mild to
cold– Interior of continents,
usually near deserts

Sub-Regions
• Desert– Hot or cold– Less than 10 inches of rain– Hot deserts: typically in southern hemisphere – Cold deserts: typically in northern hemisphere

Sub-Regions• Mediterranean– Dry and hot
summers– Cold and rainy
winters• Tundra– Near Arctic
Ocean– Permafrost– Less than 15
inches of rain– Summer lasts
only for a few weeks

Soil and Vegetation Regions
• Ecosystem: interdependent community of plants and animals– Regional ecosystem: biome• Forest, grassland, desert, tundra
![Page 13: Unit 1: The World Physical Geography. Weather Condition of the atmosphere at a particular place and time Climate-weather conditions a particular location.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649f145503460f94c299a8/html5/thumbnails/13.jpg)
Soil and Vegetation Regions
• Forestlands– Deciduous trees:
drop leaves in the fall
– Coniferous trees: cones, don’t drop leaves/needles
– Rain forest
