Document Summary

Mantle is composed of liquid iron and magnesium silicates (forming a rock called peridotite). Outer crust is composed of lighter rock such as basalt and granite: planets that formed closer to sun (mercury to mars) are small, dense and rocky which are called terrestrial planets. Giant planets have low densities and are called the jovian. Obduction zones" pushed in: transform plate boundaries are where plates simply slide past each other, mor are key source of mineral deposits, convergent plate margins: 4 main types. 2. ocean crust vs ocean crust (subduction) japan, indonesia (creates volcanic island arcs) 3. ocean crust vs continental crust (subduction) west coasts n and s. America (creation of mountain ranges on continental crust) Atlantic: density of ocean crust increases as ages. Continent formation: rate of subduction is faster in east than west, cannot subduct continental crust, only oceanic crust. Ocean formation: continent undergoes extensions when crust is thinned and rift valley forms (ex.
