directions: drag the correct answers to the boxes.
a vertical sequence of rocks is shown below.
interpret and label the rock types shown as sedimentary or igneous in this series of rock layers.

igneous
= a
= b
= c
= d

Explanation:

The question is about classifying rock types (sedimentary or igneous) in a geological cross - section. Sedimentary rocks are formed from the accumulation of sediments, often in layers. Igneous rocks are formed from the cooling and solidification of magma or lava.

• For layer A: It has a layered appearance typical of sedimentary rocks.
• For layer B: It has a texture that could be from sediment accumulation (sedimentary).
• For layer C: It has a more chaotic, possibly intrusive (igneous) texture.
• For layer D: It has a distinct igneous (possibly intrusive) contact with the surrounding rocks.

Answer:

A = sedimentary, B = sedimentary, C = igneous, D = igneous
