The average composition of the oceanic crust is thought to approximate that of what?
The average composition of the oceanic crust is thought to approximate basalt, which is a type of mafic (rich in magnesium and iron) igneous rock. It typically consists of minerals such as plagioclase feldspar, pyroxene, and olivine.
Why is oceanic lithosphere subducted while continental lithosphere is not?
The density of the continental (granitic) lithosphere is lower than oceanic (basaltic) lithosphere. Consequently, due to buoyancy, the continental crust rides above the oceanic lithosphere and thus is not subducted. However, it is thought that pieces of the continental lithosphere break off and are subducted along with the oceanic lithosphere.
What happens when continental and oceanic lithospheres collide?
When oceanic lithosphere and continental lithosphere collide, the continental lithosphere may be obducted over the oceanic lithosphere or the oceanic lithosphere may be subducted under the continental lithosphere. The latter is thought to be more common. This subduction and obduction generally results in tectonic activity such as volcanoes and earthquakes.
Meteorites are thought to be analogous in composition to Earth's core?
While some meteorites may contain iron and nickel like Earth's core, they are not fully analogous in composition. Meteorites also contain a variety of other materials such as silicates, oxides, and other minerals that are not found in Earth's core.
The composition of the core of earth is thought to be what?
The core of the Earth is thought to be mainly composed of iron and nickel, with a solid inner core and a liquid outer core. The inner core is under immense pressure and temperature, causing the iron to solidify despite high temperatures. This composition is based on seismic waves and studies of Earth's magnetic field.
What is the average composition of the oceanic crust is thought to approximate?
granite

Collisions between oceanic plates and continental plates are thought to result primarily from?
the denser oceanic plate subducting beneath the less dense continental plate due to differences in density and composition. The force of gravity drives this process as the heavier oceanic plate sinks into the mantle, leading to the formation of deep-sea trenches and volcanic arcs on the continental plate.
Are all oceanic 29 gallon biocube tanks acrylic?
I thought that they are all glass.
What is difference between paragraph and composition?
Paragraph is based on one thought or one idea. However, a composition made up of on the paragraphs.
Is The composition of Earth's core is thought to be the same as the composition of many meteorites?
Yes, this is because many meteorites derive from bodies that formed and differentiated (like the Earth) early on in the formation of the solar system but were then shattered by impacts, exposing their core material. This material is thought to be an analogue for the composition of Earth's interior.
Why did van gogh paint almond branches in bloom?
He saw what he thought was a beautiful composition and painted it.
How many days is 90 months?
Calendar months (Gregorian) vary in length from 28 to 31 days, with 30 days being a very approximate average. A duration of 90 days is generally thought of as a 3 month period (3 X 30 days).
