Transcript of The Earth and the Moon

The Solar System:
The Earth and the Moon

Most Interesting Parts
- Earth's Magnetic Field: This part of the book is interesting because the magnetic field acts as a shield against harmful particles and without it, Earth would be inhabitable
- The Brittle Crust: This is interesting becuase it talks about the part of the Earth that we stand on
- Volcanism: This is interesting because it talks all about volcanoes and how they are formed and why they erupt
- Formation of the Moon: This is interesting because it talks about how the Moon has changed over billions of years and the Moon's orbit
- Missions to the Moon: This is interesting becuase it talks about the missions to the Moon that have been attempted and how there are many more discoveries to be made
Summary
1. Earth is a sphere that orbits the Sun in a path shaped like an ellipse.
2. Seasons are created by the tilt of the planet's rotational axis, called its obliquity.
3. The more extreme the obliquity, the more extreme the planet's season's. The Earth's obliquity is intermediate in comparison to all of the other planet's.
4. The crust makes up only 0.5 percent of the Earth's total mass.
5. The crust of the Earth is significantly different from the crusts of other planets.
6. The Earth's magnetic field has a North and South Pole with magnetic field lines that flow between them.
7. The aurora australis are streaks of light caused by the high-energy particles of the solar wind striking the Earth's ionosphere.
8. A billion years after the formation of the Earth, simple blue-green algae developed and were the only life on the planet for another 2 billion years.
9. The Moon is now thought to have formed from the debris left when a giant meteorite struck the Earth.
10. For billions of years, the Moon had active volcanoes dotting its surface.
11. The orbital relationships of the Earth, Sun, and Moon create the phenomenon of the eclipse.
12. More than 60 lunar spacecraft missions have been attempted, 12 astronauts have walked on the surface, and more then 840 pounds of lunar rock and soil have been brought to Earth.
Connection
My connection with this book is I live on plant Earth, and the things that happen in it, along with the Moon, affect me and the other people living on it.
Journal
I learned a lot from my nonfiction book, The Earth and the Moon. The title of this book pretty much sums up exactly what I learned from it, a whole bunch about the planet Earth and the moon that revolves around it. The book explained the interior of the Earth and the layers that make it up. And, the book talked about the evolution of Earth and how it came to be. Also, I learned about the visible features on Earth's surface and the life on it. I learned a ton about the moon, too. The book explains the formation and evolution of the moon, the moon's interior and surface, and the missions that have been made to the moon. There is much more to be discovered about the moon and the planet that we live on. I found this book to be very informative and interesting. Also, it was clear and easy to understand. I definitely recommend to anyone who want to learn about the Earth and the moon.
