How is continental crust different from oceanic crust? answer It is the solid rock layer upon which we live. It is either contin
ental or oceanic. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser, can be subducted, and is constantly being destroyed and replaced at plate boundaries.
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
<u>Sunspots</u> are temporary phenomena on the photosphere of the Sun that appear as dark spots compared to surrounding regions. They are caused by intense magnetic activity.
