Can You help me please with HW, Geology qustions and 1 question on the picture, Thank You so much !

1. What is the outcrop pattern of a plunging syncline?

a) The layers will be oriented parallel to each other.

b)The layers will intersect at right angles.

c)The layers will close to a point in the direction of plunge.

d)The layers will open up in the direction of plunge.

2. How is magma generated along subduction zones?

a)Friction from colliding plates melts mantle material.

b)Decompression melting of the mantle from weight reduction.

c)Fluids are dehydrated out of the descending plate, which lowers the melting point of the surrounding mantle.

d)Radioactive decay melts mantle material.

a) The layers will be oriented parallel to each other.

b)The layers will intersect at right angles.

c)The layers will close to a point in the direction of plunge.

d)The layers will open up in the direction of plunge.

Explanation / Answer

Answer for question no.1

Answer is d) the layers will open up in the direction of plunge.

The layers will open up in the direction of plunge is the outcrop pattern of a plunging syncline.

The layers will close in the direction of plunge is the outcrop pattern of a plunging anticline.

Answer for question no.2.

Answer is a) Friction from colliding plates melts mantle material.

Friction from colliding plates melts mantle material is magma generated along subduction zones.

Subduction zone is a convergent plate boundary.
