Intro to Geography
Transcript of Intro to Geography
What is geography?
Geography is the study of the distribution and interaction of physical and human features of the Earth.
How do we use geography everyday?
Find Locations and Maneuver Roads
Check Weather Conditions and Forecasts
Orient Yourself Using Visual Clues
Where is an object?
The exact place on Earth where the feature is found using lines of Longitude and Latitude.
The city of Newark, DE is located at
How a place is related to its surrounding environment.
Ft. Delaware is on Pea Patch Island midway across the Delaware River from Delaware City.
What is at a location?
Physical and cultural features that set a place apart from others.
Because human interactions with the environment and cultures change over time, place can change over time.
Groups locations and places based on similarities and differences.
recognized borders established by governments.
organized around a set of interactions or connections.
people see the characteristics of the region in the same way.
How do people relate to the physical world?
How do people shape the lands they live on?
How do the lands affect culture and the way people live?
How do people, goods, and ideas move from one place to another?
How far across the Earth one location is from another.
the amount of time it takes for a person, good or idea to travel.
the way people view distance
1. Areas you are more familiar with seem closer than areas you know less about.
2. Distances seem larger when you are younger, but seem to shrink as you get older.
How do the
5 Themes of Geograph
y apply to DAPSS?
4. Human-Environment Interaction
CHECK FOR UNDERSTANDING
2. Compass Rose
4. Map Scale
7 & 8
Map scale determines how much detail will be shown.
Small Scale: Less detail
Large Scale: More detail
Which map is a large scale map?
Which map presents information in a larger scale?
What are longitude and latitude?
What are they used for?
How do we tell them apart?
What are the names of the 3 major grid lines?
Imaginary grid lines used to show exact location.
Longitude- 0-180 running north to south
Latitude- 0-90 running east to west.
Prime Meridian (0° Longitude)
International Date Line (180 ° Longitude)
Equator (0 ° Latitude)
Show the features of the Earth’s surface.
Show the features of the Earth created by people.
Ex cities, countries, states.
Representations of the Earth to show patterns in data over space.
Use colors, symbols, dots, or lines to show patterns over a geographic area.
Information is presented about a country based on a set of data other than land area.
Sizes of countries vary in proportion to the data being displayed rather than land area.
Use arrows to illustrate movement across a geographic space.
Arrows tell us the location, direction, and scope of the movement being examined.
Make Your Own Map:
Using your neighborhood, house, or school create a map showing where things are located.
Your map must include:
a key with at least 3 symbols and 3 colors.
Your map should be neat, colorful, and creative, completed on graph paper or computer paper ONLY.
Be sure to include lots of detail
Have the following terms listed, defined, and provided with an example.
4. HUMAN-ENVIRONMENT INTERACTION
9. PHYSICAL MAP
10. POLITICAL MAP
11. THEMATIC MAP
12. QUALITATIVE MAP
14. FLOW-LINE MAP
Structure of the Earth
How Plates Move
Magma in the mantle:
rises towards the crust.
As magma rises it:
begins to condense
circulate back down
Cycle continues like a conveyor belt beneath the earth.
Fault: area between two plates
Divergent: magma rises as plates spread, cools when it comes into contact with water and forms new rock.
Convergent: builds up mountain chains.
Subduction: causes volcanoes to form.
Collision: causes build up of mountains.
Transform: causes earthquakes as two plates try to slide past each other.
Breakdown / transformation of rock.
physical forces break down or reduce a rock to smaller and smaller fragments, involving no chemical change.
breakdown of rock and sediment by chemical processes.
The end result changes the chemical composition of the rock.
Plates slide past each other creating friction, sudden release of energy cause quakes.
EX: Earthquake in California
Undersea quake causes tsunami
Plates spread, new magma rises and cools forming new oceanic crust.
EX: Red Sea widens
Marianas Trench deepens
Plates slam into each other violently causing the rising of new peaks.
EX: Building of the Himalayas
Building of the Rockies
1. Rock bounces along the bottom of a fast moving river, getting smaller and smoother as it travels along the river.
2. Burial of toxic materials underground causes the decay of soil material, overtime creating a sinkhole.
3. Iron railing comes into contact with water for a prolonged period of time causing the formation of rust.
4. Water fills cracks in the asphalt when it rains, as it gets colder, the water freezes into ice, causing the crack to expand into a pothole.
5. A new, volcanic island appears in the Pacific. What could have caused this?
6. Two plates slide by each other off the coast of Japan. The impact this has on Japan would most likely be which two types of events?
