Answer:
Hardness of a mineral is defined as the resistance to breaking, and density is defined as the mass of a substance per unit volume.
The density and hardness of a mineral, that is formed from through metamorphism are relatively much harder because the metamorphic minerals are formed under extremely high temperature and pressure conditions. These are high-grade minerals.
On the other hand, the density and hardness of a mineral formed through evaporation are much weaker in nature, because these minerals are formed when the water is eliminated due to the high rate of evaporation.
So, it can be concluded that the density and hardness of as mineral formed through the metamorphic process is highly stronger and harder than those that are formed through evaporation.
Answer:
2
Explanation:
Oxygen has 6 in the outer shell. So in order to complete its octet it only needs two electrons. Like in the Water molecule, oxygen forms covalent bond with two hydrogen atoms.

Sediments can be deposited by wind or water but water moves most.
Loess is wind deposited particles. Alluvium is water deposited soil.
The particles are one part but the place they settle impacts how they become rock because the geologic process will be different at the bottom of a deep marine sea than it is in a shallow off shore shelf.
Only the very smallest particles will be moved to mid-ocean but there will be many plankton and other organic deposits.
Coastal particles will vary in sizes . Water temperature will have more impact on the organic contributions here. Shallow tropical waters have coral and can form limestone.

Answer:
B. Stabilizing selection
Explanation:
When natural selection acts against the extreme phenotypes but favors intermediate variants, it is called stabilizing selection. Stabilizing selection is mostly operative in the population s that are well adapted to the prevailing environmental conditions. Individuals with average or intermediate phenotypes are favored by stabilizing selection.
In the given example, the elk population maintains the antler size over generations. Most of the elks have intermediate-sized antlers while only a few have larger or smaller antlers. Since the average antler size (the intermediate phenotype) is favored over the extreme ones (larger or smaller sized antlers), the population is experiencing stabilizing selection.
