Each year we survey nearly 13,000 brides that have gotten married in the last year to find out their wedding budget, style preferences, and other key details. It's called The Knot Real Weddings Study, and we have to be honest, our findings are eye-opening. For starters, the national average cost of a wedding is at an all-time high since we started the survey in 2008. National wedding budgets on average are at $29,858. Before you gawk at that, keep in mind that this is an average and that depending on where you live, that number might be lower or higher (talking to you NYC brides). See the stats below â broken down by category.
The continental crust is made mostly of rocks with a composition similar to granite (a light-colored rock you would expect to find in the Sierra Nevada), whereas the oceanic crust is made mostly of rocks with a composition of basalt (a dark-colored rock, like the rocks that make up the Hawaiian volcanoes).oth oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor.
It is the floor of the oceans where oceanic crust lies. This article takes a close look at the crust of the earth that is covered by the oceans. What is the Oceanic Crust made of â Facts Oceanic crust is thin and very dense. Oceanic crust makes up just 0.01% of the mass of the earth. It has a thickness of almost 7 kilometers and it is basically made of basaltic rocks. The floor of the oceans is made up of rocks containing mainly silica and magnesium. This is why it is referred to as Sima.
