-
1)Geography is the study of the world and everything in it.
2)Geography is where something happened and why it happened when it did.
3)Geography is a spacial subject, allows us to look for patterns - Name the five map components
-
1)scale-measures didtance on map compared to real life.
2)compass rose-tells the direction.
3)Grid (graticle)-location
4)Legend explains the simbles used on a map
5) title- tells what map is a bout - Name the five themes
-
1)location
2)H.E.I Humen Environment Interaction
3)Movement
4)place
5)region - What is location?
-
Location is where something is
There are two types of location
*relative
*absolute
Relative is describing a place with very descriptive words of it's surroundings
Absolute is telling someone where a place is on a map - What is H.E.I
-
H.E.I. stands for human environment interaction
it's when people us the worlds recources to help us and how they hurt/help the enviroment - What is place
- Place- an area that has distictive features that are phisical and human
- what is movement
- Movement- the exchange of people, goods, and ideas
- what is region
-
Region-is a group of places with at least on characteristic
Two regions
*formal
*functional
formal-an area which a certain characteristic is found through out the area
Function-consists of one central place and the places affected by it
formal examples-state city, corn belt all going to have one characteristic
functional examples-amazon draining bason New York City metropolitan area - name the 7 continents
-
1) North America
2)South America
3)Antarctica
4)Africa
5)Europe
6)Asia
7)Austrailia - Name the 4 oceans
-
1)Pacific Ocean
2)Atlantic Ocean
3)Indian Ocean

- How many people from the army joined national geographic
- 656,000
- how many layers of the Earth?
- 3 layers
- name the three layers for the top to middle
-
1)crust
2)mantle
3)core
Core
*Inner
*outer core - Who is Alfred Wegener. What did he do?
- Alfred Wegener discovered continental drif in the 1900's
- How did he figure out continental drift?
- Alfred wegener thought of but didn't know how to prove it. One night he figured is out when his dughter was playing with a puzzle and she was moving the pieces around and he figured it out that the earth was one big puzzle
- What was one way that he thought how the plates moved
- One way he thought of the way that the plates moved was that he thought that the plates moved by the moon because the moon controls the tide and he thought that the tide would rais up and move the plates around and place them down again
- Did people ever believe him?
- No, no one beleived him because he had no evidence
- when did people figure out that it was true?
- In the 1950's two scientists went back to his theory and wanted to prove it so they figured out that there were plates. which caused the continents to move. They called it the Plate tectonics theory
- Name the 1 continent 200 Million years ago and what was it like.
- 200 Million years ago the continent was called Pangea and it was one big circle
- what was the 2 continents name 135 million years ago
-
1)Laurasia
2)Gondwada - What is Tectonics?
- Tectinics is a greek word which means to build up
- What is the plate tectonic theory?
- The theory is theat the shell (crust) is fractured & the pieces are shifting
- Name some of the plates.
-
1)Arabian Plate
2)Eurasian Plate
3)Antartic Plate
4)Indo-Aulstralian Plate
5)Philipine Plate
6)Pacific Plate
7)North American Plate
8)Caribbean Plate
9)Cocos Plate
10)Nazca Plate
11)South American Plate - When did the Earthquak in sanfransisco
- October 7 5:04 PM
- How long did it last for?
-
lasted 15 seconds 2 billion$ wasted
62 people died - What happens with the heat in the core?
-
The heat rises until it reaches the crust then cools and goes back to the core and starts the cycle all over again
this is what moves the continents. - Name the four types of movement.
-
1)Subduction
2)Rifting/spreading
3)Converging
4)Faulting - What is subduction?
- Subduction is when one oceanic plate hits the continental plate and the oceanic plate goes under and all the water goes into the mantle and the which causes steam and a volcanowould form by ash then it will erupt
- What is rifting?
-
Rifting is when two plates split open and go in opposit directions and which causes little hills going over and over again and if there is lava under the plates the lava will go between the hills which will cause a stream of lava
and if there isn't lava the extra land still their will collapse and will cause a hole - What is converging?
- Converging is when two plates converge and they from a mountain.
- what is faulting
- faulting is when to plates side by side going in opposite derections
- what is a trench
- very deep in the water
