How are vascular tissues arranged in dicot stems?
xylem is near leaves, phloem is near roots.
xylem forms an outer ring around phloem.
xylem and phloem are bundled randomly.
phloem forms an outer ring around xylem.

what's the question ?

1. law of superposition: when there are horizontal layers of rock. the layers at the top are the youngest.

2. law of uncomformity: where one layer is much younger than the previous one, therefore creating a gap in the time record.

3. inclusion: when there is a solid stone inside of another.

4. intrusion: a feature formed when a stone is filled with magma.

hope i answered your question.
