Answer:
A. Fossils of organisms that lived in warm climates have been found in arctic environments.
Explanation:
One of the logic used by Geologists to justify plate movement over a region of space is that the fossils of organisms that lived in warm climates have been found in arctic environments.
- this is as a result of plate tectonics.
- organisms that are well adapted to warm climates in times past have their relics preserved as fossils.
- their fossils are no found today around the arctic environment which are cold
- this suggests that the plate must have drifted or moved

the answer to number 9 is A.
Explanation:
Answer:
The atoms of some elements share electrons because this gives them a full valence shell just like the nobal gases GOOD LESSONS ♡
physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved
Explanation:
The boiling of water is a physical change because the original properties of the water is preserved.
- A physical change is the one that alters the physical properties of matter.
- This kind of change is easily reversible as the water can be cooled back.
- No new kinds of matter is produced in this kind of change .
- The molecules of the matter still retains their property after.
During the boiling of water, intermolecular bonds called hydrogen bonds between the water molecules are broken. This makes the individual molecules free.
