Interactive Sea Floor Spreading Games

Rocks on the seafloor on either side of a mid ocean spreading ridge preserve a record of the earth s magnetic field over time.

Interactive sea floor spreading games.

Plate tectonics and sea floor spreading for science interactive notebooks teaching the concept of sea floor spreading can be easily modeled using my simple yet powerful interactive resource for science interactive notebooks. Search for the seafloor. The discovery of this phenomenon was an important bit of evidence that helped confirm the theory of plate tectonics. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube.

Once the basalt cools completely into solid rock the. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart making new room for the process to repeat. Seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. This interactive activity is simple to prepare and to execute and allows the students to understand seafloor spreading and the position of newer rock and older rock in relation to the mid oceanic ridge.

The cycle of new seafloor forming and old seafloor subducting is extremely slow with the plates shifting just a few centimeters per year. South becomes north and north becomes south. As magma starts to harden into rock iron rich minerals solidify first. In total there are nine games in this learning objective including.

Their crystals are pulled into alignment by the earth s magnetic field just like a compass needle is pulled towards magnetic north. Review games like crazy taxi pacman and soccer merged with trivia questions about review for miniquiz to review and study for tests 48350. Most basalt magmas contain abundant molten iron. Seafloor spreading is the movement of magma through a crack in a mid oceanic ridge.

Bbc earth recommended for you. The interactive animation below illustrates this concept. Because it takes a long time for the crust to move the crust at the trenches is about 200 million years old. For example every million years the earth s magnetic poles tend to reverse 4 or 5 times.

Play continental drift and seafloor spreading games in an arcade style format. The rocks on the seafloor show the history of the magnetic changes in the earth.
