The "iceberg analogy" for the isostatic equilibrium of the continental crust turns out to be quite the relative density of icebergs versus seawater is close to the relative density of continental crust versus mantle. Glacial ice is about 15% less dense than seawater; likewise continental crust is about 15% less dense than the mantle.

Transcribed Image Text: Which statements about Earth's crust are true? Check all that apply. O The crust includes soil, rock, and water. O There are three different kinds of crust. O The crust is thickest under the ocean. O The ocean crust is made of young rocks. O The ocean crust is denser than continental crust.

Solution for An element makes up 0.0021% of the Earth's continental crust by mass. Express this in ppm (parts per million), to an appropriate number of…

The continental slope is a steep structure that marks the boundary between continental crust and oceanic crust. The inclination of the continental slope varies from location but has an average of about five degrees in places exceeds twenty-five degrees. The continental slope merges into a gradual incline known as the continental rise . The ...

Transcribed Image Text:.Compared to the oceanic crust, the continental crust is usually A) thicker, with a less dense granitic composition B) thicker, with a more dense basaltic composition C) thinner, with a less dense granitic composition D) thinner, with a more dense basaltic composition

C) Island arcs (oceanic/oceanic crust collision) D) Continental rift valley (divergent boundary within a continent)

Which of the following is a true statement about the Earth’s crust? The thinnest crust exists where mountains have been uplifted on the surface The crust contains one major rock type which is similar to the rocks made in the mantle Only the continental crust comprises the lithosphere The thickest continental crust exists where mountains have been uplifted on the surface The …
