... Oxidation of metals with oxygen to form a metal oxide In some cases a thin layer of oxide coats the metal surface, preventing further oxidation (Al2O3) When iron corrodes, the process is called “rusting”. The iron oxide (Fe2O3) flakes off, exposing more metal to corrosion. ...

Earthquake and Volcano Readings
... Earthquakes may also involve vertical crustal movements. During the Alaskan earthquake of 1964, large areas of land were uplifted or dropped down several meters. In fact, some sections of the seafloor along the coast were raised above sea level, becoming dry land. Strong earthquakes can be deadly. ...

... Seafloor Spreading (cont.) • Magma erupts on Earth’s surface as lava, which cools and crystallizes on the seafloor, forming rock. • Because the lava erupts into water, it cools rapidly and forms rounded structures called pillow lavas. • As the seafloor continues to spread apart, the older oceanic c ...
