When magma experiences assimilation or partial melting it becomes:
Ugo [173]

Answer:

b. more felsic

Explanation:

The sequnce of crsytallization of magma  as , first is the ultramafic which is at at very high temperature ,  then is mafic at intermediate temperature , and felsic at lowest lowest temperature , at the final stage .

Hence , the composition of earth beneath the surface is like mafic while the surface has felsic .

When the crystallizing magma is assimilated  or contaminated with the crystal rock and then the magma enhances the light color or the felsic minerals added into magma due to the assimilation of the crystal rocks .

Therefore , the magma increases the felsic nature via assimilation .

Now , When a rock undergoes partial melting , then low temperature or light color minerals released first into melts and hence , becomes more felsic .

Based on the relative positions of the sun and Earth, explain why Earth has climate zones and seasons.
Fudgin [204]
As we know the Earth is on a tilt. So when Earth revolves around the sun we rotate also. Making it so that as we spin, one hemisphere will get the most sunlight. Therefore that hemisphere will have summer at that time. So for example say that the Northern hemisphere is getting the most sunlight right now, so that hemisphere is now going to have summer. While the Northern hemisphere has summer that means that the Southern Hemisphere is having winter. But also as we rotate then at one time the Northern will have fall and the southern will have spring. Or visa versa. Climate mostly moves with the sunlight and depends on the area.
