<>"movement of weathered materials from one location to another by agents such as water (ocean currents, waves, rivers), wind, glaciers, and gravity. Fact: moving water is the most powerful agent of erosion."<>
Answer:
Currents are physical occurrences or factors that put motion into oceans, making them move back and forth.
Such factors include but may exceed the following:
- Wind
- Variation in water mass densities (this is caused by alterations in temperature and salinity levels)
- Gravity
- Earthquakes or storms
When there is movement in ocean currents, heat, nutrients, water oxygen levels are also affected.

Answer:
C. Y & Z
Explanation:
V, W are imaginary metals here because their valence electrons are typically less than 4. X, Y, Z are non-metals and have higher valence electrons. Here, if V or W bind with X, Y, or Z we make ionic bond (because metal + non metal = ionic). But, if X binds with Y or Z or any combinations of any two of the three non-metals results in covalent bond (non metal + non metal = covalent).
Thus, Y and Z make covalent.

Hydrogen is the element with atomic number one. The representation of the hydrogen molecule with a double bond is incorrect.
<h3>What is a double bond?</h3>
A double bond is a type of chemical bond that involves two pairs or four bonding electrons of the atom in a molecule. They are stronger and shorter bonds compared to single bonds.
A hydrogen molecule can never have a double bond in its molecule as it has only a single electron in its shell and cannot form a double bond due to the lack of four electrons.
Therefore, hydrogen molecules cannot form a double bond.
