What are some notes for Magnetism and Plate Tectonics
Magnetism:
• Earth’s magnetic field is generated by the movement of molten iron in the outer core.
• The Earth’s magnetic field is constantly changing and can reverse its polarity.
• Magnetism is used to measure the age of rocks and to study the Earth’s interior.
Plate Tectonics:
• Plate tectonics is the theory that Earth’s outer layer is made up of several large plates that move and interact with each other.
• Plate tectonics explains the formation of mountains, volcanoes, and earthquakes.
• Plate tectonics is responsible for the distribution of landforms and climate around the world.
