Answer:
The crust is the outer layer of the Earth. It is the solid rock layer upon which we live. It is either continental or oceanic. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser, can be subducted and is constantly being destroyed and replaced at plate boundaries. Continental crust is older, lighter and cannot be destroyed.
The oceanic and continental crust differentiate by composition and thickness. Oceanic crust is thinner and denser, composed mostly of basalt and gabbro, while the continental crust is thicker, less dense, and comprised of granitic rocks.
The oceanic and continental crusts form the outermost layer of the Earth. They differ from each other in terms of composition and thickness. The oceanic crust primarily consists of mafic rocks like basalt and gabbro and is about 5-10km thick. Because of its denser composition, it sinks beneath the continental crust when the two come into contact, leading to a process called subduction. On the other hand, the continental crust is mainly composed of granitic rocks and is much thicker, typically ranging from 30-50km. It is less dense than the oceanic crust and when the two collide, the continental crust stays above.

Answer:
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the east of IC 1396A. (In the Spitzer Space Telescope view shown, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars.[2][3]

Answer:
fr, I only got this because I'm flipping dumb and for study island like why would you even ban people if this "app" was made for cheats. like there saying that this app improves people knowledge this is basically a freaking TEST KEY!
