Answer:

It is thin & mostly made of granite and limestone :0

Explanation:

The oceanic crusts are thin and are usually about a thickness of about 5 to 7 km. They contain rocks that are poor in silica and mostly enriched in magnesium (Mg) and iron (Fe). Due to the divergent motion of plates, seafloor spreading takes place as a result of which the hot molten magma comes out to the ocean floor and immediately cools down and gets solidified along the mid-oceanic ridge. The rock types produced here are mainly basaltic in nature. Basalt is a mafic rock and is comprised of denser minerals due to which the oceanic crust is relatively denser than the continental crust. Pillow basalts also form in this region.

Thus, the crust that is present beneath the Atlantic ocean is also comprised of basaltic to andesitic in composition.

3. How do First Amendment protections of freedom of assembly apply to private versus public

harkovskaia [24]

<span>The First Amendment prohibits government from abridging "the right of the people peaceably to assemble." People are entitled to assemble and to speak and be heard, as long as they remain nonviolent. This basic freedom ensures that the spirit of the First Amendment survives and thrives even when the majority of citizens would rather suppress expression it finds offensive</span>

Which was not a feature of Romanesque architecture? Small windows Pointed arches Thick stone walls Rounded arches

HACTEHA [7]

I believe the answer is pointed arches, correct me if I'm wrong.
Romanesque architecture has thick stone walls, small windows, and rounded arches. I do not believe they have any pointed arches. As you can see in the photo attached there are all of the above, except pointed arches.

Hope this helps!
