What can crystalize size tell us about where an igneous rock formed?
sergejj [24]

Explanation:

The size of crystals in igneous rocks can tell us about the physical environment under which the rock formed.

Igneous rocks are rocks that are derived from molten magma formed within the crust.

  • When large crystals are formed, it suggests that the magma has cooled slowly without any disturbance. Slow cooling of magma makes minerals to surround nucleation centers easily an take their time to form.
  • When small crystals are formed, we can infer that cooling was rapid. Magma had to cool rapidly and several nucleation centers resulted.
  • Large crystals in rocks are usually produced deep beneath the earth crust forming a rock type known as plutonic igneous rocks.
  • Those with small crystals that forms on the surface are called extrusive or volcanic igneous rocks.

What evidence shows that white dwarfs must be very small?
Drupady [299]

Spectral analysis proposes that there is no hydrogen fusion roughly speaking. They are hot since they are very thick. So if you are a convinced high density and temperature and still not doing synthesis, you must be small. Also, stellar evolution models are founded on the observation of planetary nebulae, where stars have shed most of their mass after being red giants. The physics designates a small, hot, central remainder.

Will give brainliest! Write a couple sentences answering the question above! No copy and paste from internet
Reika [66]

Answer:

During photosynthesis the tree while convert the energy from sunlight into sugar (glucose). The xylem will transport the water to the leaves. The phloem will transport the glucose. The energy from sunlight will also be used to convert water and carbon dioxide into oxygen and glucose. Hence, the energy stored within the glucose/sugar molecules will be used to help the tree grow.

Explanation:

I wrote it in my own words but it will probably say i took it from go ogle since used similar terms apparently.

hope this helps and is right. p.s i really need brainliest :)
