Answer:
Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river's delta.
Explanation:
Answer:
d) Metallic character decreases as you go to the right across a row in the periodic table and increases as you go down a column.
Explanation:
- <em><u>Metallic character decreases as you move across a period in the periodic table from left to right.</u></em> This is because the attraction between valence electron and the nucleus increases, making it difficult for loss of electrons. It occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell.
- On the other hand, <em><u>Metallic character increases as you move down an element group in the periodic table.</u></em> This is due to the increase in atomic radius as the number of energy levels increases.
