1. Inquiry Activity What features can you identify in this photo?
Where do you think this photo was taken?
If you were an Earth scientist, how could you use this photo in your work?

2. Let’s see what you remember

3. Pretest (page 6)
T/F: Our solar system consists only of Earth and the sun.
Object A is denser than water. If object A is dropped into a cup of water, what will happen to the object?
What is Earth know to have that other planets in our solar system are not known to have?
Volcanoes
Rings
Liquid water
What is the name of the imaginary horizontal line that goes around Earth’s middle?
What is the name of the imaginary vertical line that goes around Earth’s middle?
What is a storm that brings strong winds, heavy rains, and coastal flooding?

4. 1.1 What is Earth Science? Today, you will be able to:
Today, you will be able to:
Define Earth science
Describe the formation of Earth and the solar system

5. Vocabulary (index cards)
Earth science
Geology
Oceanography
Meteorology
Astronomy
Ecology
Ecosystem

6. What is science?
System used by humans to learn about the natural world around them
When you observe the world around you and ask questions, you act like a scientist.
The goal of science is to understand the world around us.

7. Well … just what is Earth Science all about?

8. Earth Science is …
All the sciences that seek to understand the Earth and the universe around it
It includes
Geology (study of the “solid” part of Earth)
Oceanography (study of the ocean)
Meteorology (study of the atmosphere)
Astronomy (study of the universe)

9. Earth Science & Biology … What’s the connection?
Ecology  describes the relationships between organisms, a.k.a. living things, and their environment
When studying communities of organisms, the environment is referred to as an ecosystem.

10. Formation of Earth
Most researchers conclude that Earth and the other planets formed at essentially the same time.
Nebular Hypothesis
The solar system evolved from an enormous rotating cloud called the solar nebula.
The nebula was composed mostly of hydrogen and helium.

11. Formation of Earth Nebular Hypothesis
About 5 billion years ago, the nebula began to contract.
It assumed a flat, disk shape with the protosun (pre-Sun) at the center.
Inner planets begin to form from metallic and rocky clumps.
Larger outer planets began forming from fragments with a high percentage of ices.

12. A. Our solar system began as an enormous cloud of dust and gases made up mostly of hydrogen and helium.
B. This cloud (nebula) started to rotate and collapse toward the center of the cloud. Heat was generated in the center.
C. Cooling of the nebula caused rocky and metallic materials to form tiny solid particles.
D. Repeated collisions of these particles resulted in the formation of asteroid sized bodies.
E. These bodies eventually combined to form the four inner planets. The lighter materials and gases formed the four outer planets.

13. Formation of Earth Layers Form on Earth
As Earth formed, the decay of radioactive elements and heat from high-velocity impacts caused the temperature to increase.
Lighter rocky components floated outward, toward the surface.
Gaseous material escaped from Earth’s interior to produce the primitive atmosphere.

14. So … why does the Earth have layers?
BECAUSE OF DENSITY!!
