Steps. 1  1. Perform major pruning during the dormant season. The ideal time to prune a crabapple tree is late winter or in the cold days of early spring, before leaves appear. 2  2. Remove suckers.

The upper crust is 12.5 km thick in crust with an average total thickness of 40 km (ref. 3). If the upper crust is the product of 14% melting, the corresponding residue would be 77 km thick, resulting in a total crustal thickness of 100 km, including the middle crust.
1.The oceanic crust is made up of basalt while the continental crust is made up of granite. 2.The oceanic crust is thinner while the continental crust is much thicker. 3.The oceanic crust is denser than the continental crust.4.The continental crust has greater buoyancy than the oceanic crust..The oceanic crust is made up of basalt while the continental crust is made up of granite. 2.The oceanic crust is thinner while the continental crust is much thicker. 3.The oceanic crust is denser than the continental crust. 4.The continental crust has greater buoyancy than the oceanic crust.
