The law of cross-cutting relationships states that an igneous intrusion or any other geologic feature of a rock must be younger than any rock it cuts.
Explanation:
Igneous intrusion is formed when the magma intrudes into the cracks of an existing rock.When the melted rocks solidifies and cool down the resulting feature is the Igneous intrusion
The law of cross cutting is basically a principle of geology that states that the geological feature of a rock that cuts the other is always younger.

Hello!
K⁺ and F⁻ are the more likely to form an ionic bond.
Ionic bonds are the result of the electrostatic attraction between positive and negative ions (charged atoms). Of the listed substances, the ones that are charged are K⁺ and F⁻, so they are the ones that will form ionic bonds. Some ionic substances made from K⁺ include KCl (used in fertilizers) and some ionic substances made from F⁻ include NaF (used in dental therapy).
Have a nice day!
