QFD: “The snake which cannot cast its skin has to die. As well the minds which are prevented from changing their opinions; they cease to be mind.” ― Friedrich Nietzsche
?FD: How do Eras end? What happens?
Objective: 1c. Students know the evidence from geological studies of Earth and other planets suggest that the early Earth was very different from Earth today.
1) Make a timeline with at least 1 fact about each period in Earths History and has a fact about the change in the atmosphere, the landmasses,and the organisms on earth then fraw a picture about your fact underneath it
2)On the back of your timeline or on another sheet of paper – You will write a 3 paragraph essay addressing: how the solar system formed, how the Earth has changed (give at least 3 examples), and what you think will happen in 200 million years in the future

QUIZ
1 Of the following choices, which BEST provides scientists with a reliable age of the solar system?
A terrestrial material from planets other than Earth
B earth volcanic rock
C fragments of asteroids known as meteorites
D metamorphic Earth rock

2 Why are rock samples from the moon helpful in determining the relative age of the solar system?
A because moon rocks have not gone through changes caused by tectonic activity
B because moon rocks have gone through changes caused by tectonic activity
C because moon rocks came from a distant solar system
D because moon rocks by their nature change over time

3 Scientists believe that, shortly after Earth formed, the decay of radioactive elements, combined with heat, produced melting within Earth’s interior. What happened to the denser materials, iron and nickel?
A both rose to Earth’s surface
B the iron sank towards Earth’s interior and the nickel rose towards the surface
C the nickel sank towards Earth’s interior and the iron rose to the surface
D both sank towards Earth’s interior

4 What evidence did scientists use to determine the age of the solar system?
A planetary alignment and volcanic eruptions
B lunar dust, rocks from Mars, and comets
C moon rocks, planetary orbit, and life span of a star
D meteorites, moon rocks, and Earth rocks

5 The evidence obtained from Earth and from moon rocks indicate the solar system __________.
A was formed about 4 million years ago

9 When the Earth’s surface became a solid crust it was covered with active volcanoes. These volcanoes released gases that became part of the early atmosphere. Which of these gases was NOT released from these early volcanoes?
A oxygen
B ammonia
C water vapor
D carbon dioxide

10 Earth’s atmosphere today contains 21 percent oxygen, but early Earth started off with an atmosphere with almost no oxygen. Which of the following BEST represents how oxygen first became prevalent in Earth’s atmosphere?
