A batholith is an amalgamation of plutons.
Plutons are bulbous masses that commonly develop beneath strings of volcanoes associated with plate subduction. Batholiths may contain vast nests of hundreds of plutons intimately crowded against or penetrating one another. The Sierra Nevada range of California and the Andes literally define the notion of batholiths.
The majority of granitic magmas are formed by melting near the base of the continents. The magmas slowly rise through the crust like great balloons. They solidify near the surface to form gigantic bodies of igneous rock called plutons, which are exposed later when uplift and erosion remove the overlying rock.

Answer:
Early people migrated south.
Explanation:
Answer:
In the Northern Hemisphere the autumnal equinox falls about September 22 or 23, as the Sun crosses the celestial equator going south.
Explanation:
In the Southern Hemisphere the equinox occurs on March 20 or 21, when the Sun moves north across the celestial equator.
The correct answer would be c because in the picture above it shows two oceanic plates colliding.
Answer:
c = 55° and d = 125°
Explanation:
Given that,
We need to find the measure of angle c and angle d.
We know that the sum of angles of a triangle is 180 degrees. So,
a+b+c = 180
85+40+c = 180
125+c=180
c = 180-125
= 55°
Using exterior angle theorem,
d = a+b
d = 85+40
d = 125°
Hence, c = 55° and d = 125°
