Big Ideas (learning targets)

• energy moves through objects of different densities at different speeds

• the outer core is made up of hot liquid iron and nickel

• Earth's iron rich core acts like a magnet

• like a magnet, Earth has a north and south pole

• wind, water, and gravity weather, erode, and deposit materials

• first comes weathering, then erosion, then deposition

• Earth's plates fit together like a jigsaw puzzle

• Earth's plates constantly move

• Earth's plates are named after the continents and oceans they carry

• The Greek word "tectonics" means "to build"

• Pangea was NOT the Earth's first supercontinent

• faults are most likely to occur along plate boundaries

• pressure along faults that is released in the form of waves of energy cause earthquakes

• magma rising to Earth's surface to erupt cause volcanoes

• surface waves are significant because they cause the most damage during an earthquake
