A relatively thin crust, which typically varies from a few kilometres to 40 km (about 25 miles) in thickness, sits on top of the mantle. 5 to 100 km thick, the average thickness is 35 km 2. Oceanic crust is about four miles thick. Thanks for the A2A. Oceanic Crust - Crust beneath the oceans - consist mainly of dense rock (basalt-dark in color) The continental crust is solid and the temperature overall is about 22⁰C.

The crust is the coldest layer of all the layers of earth. The crust is about 40 kilometers thick in many places. The crust makes up less than 1% of the earths mass. Here on solid ground, on the continental shelves, the crust of the Earth is about 30 km thick. In the mid-ocean, the thickness of the crust can be as little as 5 km. The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick, and it is mostly composed of less dense rocks than is the oceanic crust. Before answering this question I would like to tell that Earth's crust is divided into 2 types, Oceanic crust and continental crust.

The thickness of Earth's crust ranges from roughly 2 miles at the mid-ocean ridges to 70 miles in thickness under some continental mountain ranges, with an average overall depth of around 27 miles. It is light and brittle and can break. (In some places, Earth’s crust may be up to 70 km [40 miles] thick.) Oceanic Crust - Crust beneath the oceans - consist mainly of dense rock (basalt-dark in color) It is less than 1% of the Earth's volume. Below the crust is the mantle.The crust and the upper mantle make up the lithosphere.The lithosphere is broken up into tectonic plates that can move.. The continental crust, or the crust that lies beneath the continents, usually ranges from around 30 to 45 kilometers thick. In plate tectonics: Earth’s layers.

The crust of the Earth is thickest beneath the continents. The crust contains of a variety of rocks. 1. The oceanic crust is 5 km (3 mi) to 10 km (6 mi) thick and is composed primarily of basalt, diabase, and gabbro. The oceanic crust is about 8km thick. The continental crust is solid and the temperature overall is about 22⁰C. The crust and the mantle contain different types of rocks making them chemically different. Average thickness varies greatly depending on geography and whether the crust is continental or oceanic. The oceanic crust of the Earth is different from its continental crust. Oceanic crust may be heavier and denser, but continental crust is a thicker and older part of the Earth's crust. 5 to 100 km thick, the average thickness is 35 km 2. The crust can be between 5km thick (in the ocean floor) to around 70km thick (on land where we live called the continental crust). The entire crust …
