Mineral of volcanic origin with large crystals is formed by magma that cooled off deeper into the crust.
Explanation:
The rocks of volcanic origin are divided into two main categories by the place of formation, extrusive igneous rocks and intrusive igneous rocks. The extrusive igneous rocks are the ones that form on the surface or near the surface. The intrusive igneous rocks are the ones that form deeper into the crust.
The intrusive igneous rocks are formed by magma that has managed to penetrate the crust, but didn't managed to come to the surface. It started to cool off slowly over longer period of time, thus solidifying. Because the solidifying has been very slow, the minerals formed in this manner have big minerals, as they had time to grow.
Minerals of this type are:
- granite
- diorite
- peridotite
- gabro

E.) Mesosphere, Asthenosphere, Outer layer
Unfortunately there is no standard terminology for three mantle layers.
<span>I can be sure that "ionosphere" and "thermosphere" refer </span>
<span>only to atmospheric layers, so you can rule out A, B, and D. </span>
<span>"Mesosphere" may be used to refer to an atmospheric layer, </span>
<span>but is also often used to refer to a mantle layer. </span>
<span>
, </span>
<span>so I'll go with E even though I don't like it much. </span>
<span>I guess what is meant by "outer layer" is the part of the lithosphere </span>
<span>that does not match crustal composition.</span>
We have to distinguish all three processes before you can apply your personal experience. Cultural diffusion is the process of one culture influencing another in a positive way by adopting or copying it. However, Cultural appropriation is a term for cultural diffusion that is seen as disrespectful or mocking and can be linked to racism. So, it has a negative connotation. Cultural assimilation occurs when a minority enters into a dominate culture and assimilates in order to survive. It is a one way process in which dominant culture always wins. The American society is a good example of cultural assimilation of minority groups.
are extinct, had hard parts,were generally large and were alive only for a short time.
Explanation:
Index fossils typically are extinct organisms that have hard parts that have been preserved till date. They are generally large in population but their body size might vary and only alive for a short period in time.
- Index fossils are also known as guide fossils or indicator fossils.
- They help to define geologic periods more appropriately and fittingly.
- Like every other remains of organisms preserved in rocks, they must have preservable hard parts.
- Their population must be abundant so as to increase their chances of being preserved.
- They must also be extinct. Extinction is the mass loss of a specie. If they are not extinct, they might not be good indicators of time. Extinction confines the life history of organism into a proper time frame.

The shape of a river channel can vary based on were it is located and what is around it the factors that control the shape of it is errioson from the water that passes through it, the vegitation that is growing around it, outside forces such as human impact, and things like sediment or other minerals that are passing through if murky water is passing through than it is more likely to leave behind minerals and dirt which could change the shape along with the other factors that i mentioned
