PHYSICAL PROCESSES: How do physical forces affect a region? WG.3.B Describe the physical processes that affect the environments of regions, INCLUDING weather, tectonic forces, erosion, and soilbuilding processes [READINESS STANDARD] YSLETA INDEPENDENT SCHOOL DISTRICT SOCIAL STUDIES INSTRUCTIONAL TEAM

Can you guess what country this is? How many “regions” do you see? Coastal Plains Interior Lowlands Great Plains Basin and Ridge Appalachian Mountains Rocky Mountains Coastal Ridge

What stands out on this map? Now, what do you see? What stands out on this map? Coastal Plains Interior Lowlands Great Plains Basin and Ridge Appalachian Mountains Rocky Mountains Coastal Ridge

Which words do you know, and which do you need help with? Tectonic Forces Earthquake Tsunami Volcano Spreading Building Lithosphere Subduction Mountain

How do “tectonic forces” affect a region? THE HESS CONVECTION CURRENT ‘SLAB-PULL’- ‘RIDGE PUSH’ MODEL Continents pushed apart by ‘Ridge-Push’ Subduction of oceanic Crust by ‘Slab Pull’ Magma Ridge-Push by diverging convection currents Subduction by converging convection currents Continental Crust pulled over the Oceanic Crust LITHOSPHERE (Tectonic means “building”. The earth is “building” itself by building its lithosphere) Describe what you see in the diagram http://www.tectonic-forces.org/simplified.htm

How does “erosion” affect a region? WATER WIND DESCRIBE WHAT’S HAPPENING TO THE LAND http://thewatchers.adorraeli.com/2011/08/08/the-first-true-view-of-global-erosion/ SOIL GRAVITY

How does “weather” affect a region? DESCRIBE WHAT’S HAPPENING TO THE LAND http://thewatchers.adorraeli.com/2011/08/08/the-first-true-view-of-global-erosion/

How does a region affect the weather? http://www.photologger.co.cc/Games/orographic-effect.html “Orographic” Effect -- Greek: Oro-- Hill, Graphic-- Write Hill writing. The hill writes its effect on the weather.

Where would the “orographic effect” be most likely? Coastal Plains Interior Lowlands Great Plains Basin and Ridge Appalachian Mountains Rocky Mountains Coastal Ridge http://thewatchers.adorraeli.com/2011/08/08/the-first-true-view-of-global-erosion/

Let’s see what we know… Which are you ready to answer, and which do you need a peek? Tectonic plate movement may be caused by all of the following EXCEPT— A slab pull B ridge push C convection D magnetism All of the following are tectonic forces that shape the surface of the earth EXCEPT— A subduction B spreading C transformation D transpiration

Let’s see what we know… Since you could answer the last question, can you answer this one? The Middle East consists of mountains, upland plateaus and valleys. These physical features are the result of: A erosion B tectonic forces C deposition D weathering

The same tectonic force, many continents… Let’s look again at “Tectonic Forces” The same tectonic force, many continents… THE HESS CONVECTION CURRENT ‘SLAB-PULL’- ‘RIDGE PUSH’ MODEL Continents pushed apart by ‘Ridge-Push’ Subduction of oceanic Crust by ‘Slab Pull’ Magma Ridge-Push by diverging convection currents Subduction by converging convection currents Continental Crust pulled over the Oceanic Crust LITHOSPHERE (Tectonic means “building”. The earth is “building” itself by building its lithosphere.)

Let’s see what we know… Which are you ready to answer, and which do you need a peek? Because of its location along the "Ring of Fire," Japan is particularly susceptible to which of the following hazards? F earthquakes and volcanoes G floodings and droughts H monsoons and floodings J earthquakes and tornados The Pacific Islands in the Ring of Fire are affected by all of the following except — A volcanoes B earthquakes C tsunamis D tornadoes

Talk to each other, and then talk to me… WG.3.B Describe the physical processes that affect the environments of regions, INCLUDING weather, tectonic forces, erosion, and soilbuilding processes. How do physical forces effect a region?
