What makes Earth a “living planet”? What color do you see the most? Blue= Water, Water =Life
Bodies of Water Oceans and Seas 71% of the earth is covered by salt water What are the major oceans? Atlantic, Pacific, Arctic, Indian and Southern
Oceanic Landforms Continental Shelf: From the edge of a continent to the deep part of the ocean. Ridges, valleys, canyons, plains and mountains all exist on the ocean floor...
Hydrologic Cycle The continuous circulation of water between the atmosphere, the oceans and the earth.
Make your own Hydrologic cycle • In your notes, create your own version of the hydrologic cycle. Does not have to look like the example.
Lakes, Rivers and Streams Bodies of fresh water
Ground Water Water that sits in the rock of the earth. The water table is the level at which the rock is saturated, or full.
Landforms Relief: The geographic feature that separates one landform from another. It is the difference in elevation from the lowest point to the highest. 4 types of Reliefs: Mountains, hills, plains and plateaus
Other Landforms: • Please turn to pgs 34-35 in your textbook • Choose 8 landforms to write into your notes (They must at least include- oasis, cliff, steppe, & plateau) • When finished, turn to your neighbor and discuss if you’ve ever seen one or more of your 8 types of landforms...
How the Earth is Shaped... Our earth is MOVING!!
Tectonic Plates Enormous moving pieces of the earth’s lithosphere
What Happens When the Plates Move?? Earthquakes Earthquakes are measured using the Richter Scale. The scales begins at 1 and has no upper limit... What was the largest earthquake ever recorded? 9.5-Valdivia Chile
Tsunami: Sometimes earthquakes cause a major wave that hits the coast
VolcanoesMagma, gases, and water gather under the earth’s mantle. Eventually, they push their way out...
Ring of Fire: A zone around the rim of the Pacific ocean where most of the world’s volcanoes are located.
Erosion... • Please turn to pg 43 in the World Geography Textbook • Take notes on the 3 types Erosion • What type of erosion is most likely to occur here in the greater Houston area?
Vegetation • Please turn to pg 66 in the World Geo Textbook • Read and take notes on the 3 types of vegetation. • What are their characteristics, Where are they located? (this should be in with your notes)
Seasons The tilt of the earth is what causes seasons to occur (Spring, Summer, Fall & Winter) Solstice: Longest and shortest days of the year Equinox: Equal day and night
Weather • Weather: The condition of the atmosphere at a particular location and time. • Climate: Weather conditions at a particular location over a long period of time. • What’s the difference between weather and climate? • Give an example…
Weather Extremes • Hurricanes: A storm that forms over warm tropical ocean waters (Typhoons in Asia) • Tornadoes: A powerful funnel-shaped column of spiraling air • Blizzard: a heavy snowstorm with winds of more than 35 miles per hour • Droughts: a long period of time without rain fall • Floods: When water spreads over land not normally covered in water
Factors that Affect Climate • 5 factors that affect climate: • Wind Currents • Ocean Currents • Zones of Latitude • Elevation • Topography • El Nino: The warming of waters off the west coast of South America (a natural change in climate)
Questions • 1. From the 5 weather extremes name the one that Houston has yet to experience. • 2. How does location affect climate?
Climate Regions (brief descriptions) • Tropical Wet: Little variation in temperature, always hot and rainy • Tropical Wet & Dry: Rainy season in the summer, and a dry season in the winter • Semiarid: Typically found around deserts or interior of continents, small amount of rain • Desert: receive less than 10 inches of rain a year (can be hot or cold)
Climate Regions (brief descriptions) • Mediterranean: Dry & hot summers, winters are cool & rainy • Marine West Coast: Cloudy, foggy & rainy, near an ocean • Humid Subtropical: Long summers of heat and humidity • Humid Continental: mid-latitude interiors of the northern hemisphere, various temperatures
Climate Regions (brief descriptions) • Subartic: Huge variations in temperature, long freezing season • Tundra: Flat, treeless land surrounding the Artic Circle • Ice Cap: Snow, ice and permanently freezing temperatures • Highlands: Rugged mountain areas
Questions • 3. Which climate zone does Houston fall into? • 4. Discuss with your neighbor which climate zone you would prefer to live in and why.
