Usually after the area they were originated
I think is heat but I’m not sure
Explanation:
Similar rock types can be used as an evidence for continental drift because rocks forms under different geologic conditions.
Most natural depression on the earth surface are filled with thick sedimentary sequences that have been subjected to lithification.
In some terrain, magmatic activities are rife with prevailing tectonic settings controlling how they cool and solidify.
Also, some terrains have experience prolong metamorphic change and this dives spurious metamorphic transformation of minerals.
- A terrain will have a rock type that typifies it.
- If the two terrains become separated, it is possible to correlates the rock sequences in them.
- For sedimentary rocks, a geologic column and stratigraphy can be useful on correlating them.
- In metamorphic rocks. different facies have typical index minerals in them that can be used to match them.
- Dating some minerals in igneous rocks and even establishing sequences have proven useful in explaining continental drift between terrains

Crossing over at prophase I results in the linked genes (those on the same chromosome) becoming unlinked and separated. Prophase I is this first stage of meiosis, the chromosomes condense, form tetrads, and exchange DNA. The nucleolus and nuclear envelope disappear.
<h3><u>Answer;</u></h3>
Opposable thumb
<h3><u>Explanation;</u></h3>
- An opposable thumb is a thumb that can be placed opposite the fingers of the same hand. Opposable thumbs allow the digits to grasp and handle objects and are characteristic of primates.
- Opposable thumbs are one of the distinguishing features of primates. Opposable thumbs of human beings allow them to use tools.
