Understanding the System
Many different parts working together to make a whole.
Ex. A car engine

Forming the Earth
Q.) How did the Solar System form?
A.) From a large rotating solar nebula made up of hydrogen (H) and helium (He).

Layers on Earth
Iron (Fe) and Nickel (Ni) sunk to the center of the Earth.
Lighter materials floated outward = formation of atmosphere and oceans.

Earth’s System
Powered by 2 sources:
1. Sun – powers external processes (atmosphere, hydrosphere, surface)
2. Core– powers internal processes (volcanoes, earthquakes, mountain formation)

People and the Environment
Q.) How do people influence natural processes?
A.) By building, cutting down forests, agriculture, etc.

Resources
2 types:
1.) Renewable – replenished over short time
2.) Nonrenewable – take millions/billions of years to form

Population
Q.) How will our basic resources last with an increase in population every year?
A.) No one knows!

Atmosphere
Keeps life going!
What does it do?
Why is it important?
![Page 14: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/14.jpg)
Geosphere
3 parts: Core Mantle Crust
Different layers because of the composition.
![Page 15: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/15.jpg)
Biosphere
Involves all life from the ocean floor to the atmosphere.
Do we change the environment we live in?

Plate Tectonics
How the Earth moves!
7 different plates
2 different forces: Destructive Constructive

Reading the Maps
Use two things:
1. Latitude:
2. Longitude:
![Page 19: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/19.jpg)
Projection Maps
Two types:1.) Mercator – the
directions were accurate
2.) Robinson- Distance, shape, size are accurate
![Page 20: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/20.jpg)
Topographic Maps
Shows the Earth in 3-D in a 2-D way
They show elevation with contour lines.
![Page 21: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/21.jpg)
Contour Lines
Contour Interval – the difference in elevation between adjacent lines.
Close lines- steep slope
Far Apart- gentle slope
Circle- hill

Scale
What is it?
What map makers use to show the distance on the map in relation to the Earth.
Ex. 1: 24,000
![Page 23: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/23.jpg)
Geologic Maps
Shows the type and age of the rocks that are exposed.
The same rocks are the same color and/or pattern.

Advanced Technology
We are now able to analyze Earth’s physical properties more precisely.
Remote Sensing – using satellites to map the Earth
GPS

Scientific Method
![Page 26: Earth System Science How is Earth a system?. Understanding the System Many different parts working together to make a whole. Ex. A car engine](https://reader033.vdocuments.net/reader033/viewer/2022051621/5697bfe01a28abf838cb34c2/html5/thumbnails/26.jpg)
What is it?
The process that all scientists follow to explore a question.
It is the same for everyone and allows for consistency.
