About This Chapter
Who's it for?
Anyone who needs help learning or mastering high school physical science material will benefit from taking this course. There is no faster or easier way to learn high school physical science. Among those who would benefit are:
- Students who have fallen behind in understanding the evidence that supports plate tectonics, the primary plates or how and why the move
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about physical science and plate tectonics
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the physical science - plate tectonics chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the physical science - plate tectonics chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any physical science and plate tectonics question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students will review:
This chapter helps students review the concepts in a physical science and plate tectonics unit of a standard high school physical science course. Topics covered include:
- Plate tectonics
- Alfred Wegener's theory of continental drift
- Evidence for the mechanism of continental drift
- Major plates of the lithosphere
- Causes of tectonic plate movement
- Plate boundaries
- Ocean drilling as evidence for plate tectonics
- Paleomagnetism and hot spots
- Sea floor spreading and polar reversal
1. What is Pangaea? - Theory & Definition
The world's continents as we know them today were formed millions of years ago when Pangaea broke apart. Learn about the origin of the continents and understand what the theory of Pangaea entails. Explore the idea of supercontinents, review the continents of Pangaea, and recognize the evidence that supports continental drift theories.
2. Plate Tectonics: A Unified Theory for Change of the Earth's Surface
Plate tectonics involve a unifying theory of how the surface of the earth changes. Explore this theory, what causes plates to move, and learn about the term lithosphere, asthenosphere, mantle, and core.
3. Alfred Wegener's Theory of Continental Drift
Alfred Wegener theorized the movement of continents, the theory of continental drift, by gathering evidence unexplained by the accepted model of his time. Explore how he studied coastlines, fossils, and geologic features to develop his theory and discover the challenges he faced.
4. Evidence for the Mechanism of Continental Drift
Scientists discovered evidence for the mechanism of continual drift. Learn about the lithosphere, plates, and faults, and consider the evidence in support of the continental drift theory.
5. Major Plates of the Lithosphere: Earth's Tectonic Plates
The lithosphere is the solid, outer part of the Earth and has seven major tectonic plates. Learn more about the lithosphere, plate tectonics, and the seven major tectonic plates.
6. Causes of Tectonic Plate Movement
Tectonic plates are huge moving pieces of the Earth's crust and there are different mechanisms that can explain the causes of their movement. Learn about the different forces and mechanisms involved in the plate movement process, including thermal convection, ridge push, slab pull, and trench suction.
7. Plate Boundaries: Convergent, Divergent, and Transform Boundaries
The three types of plate boundaries are divergent, convergent, and transform boundaries. Explore these boundaries, the theory of plate tectonics, and how convection currents cause the Earth's plates to move.
8. Ocean Drilling as Evidence for Plate Tectonics
One of the ways that scientists study the ocean floor is through deep sea drilling projects, which began in the 1960s. Learn more about the first Deep Sea Drilling Project (DSDP) and how it led to more scientific discoveries about plate tectonics, the Mid-Atlantic Ridge and seafloor spreading.
9. Paleomagnetism and Hot Spots: Evidence for Plate Tectonics
Plate tectonics is a scientific theory used to explain how the Earth's surface, including the continents and oceans, has moved in the past as well as in the present. Explore plate tectonics and learn about paleomagnetism and hot spots, which provide evidence to support plate tectonics theory.
10. Sea Floor Spreading and Polar Reversal
The discovery of the Mid-Ocean Ridge opened the door to understand sea floor spreading and polar reversal. Learn about how normal and reversed polarity that was discovered in stripes along the ocean floor allowed scientists to understand how the sea floor spreads.
