Metalloids are metallic-looking brittle solids that are either </span>semiconductors<span> or exist in semiconducting forms, and have </span>amphoteric<span> or weakly </span>acidic oxides<span>. Typical nonmetals have a dull, coloured or colourless appearance; are </span>brittle<span> when solid; are poor conductors of heat and electricity; and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise extraordinary.</span>

Which of the following statements is true?
Lelu [443]

Answer:

The true statement is: "Spring tides are the highest, while neap tides are the lowest."

Explanation:

  • The range of difference in the level of water between high and low tide is always larger in spring tide.
  • Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun)  balances the bulge of the ocean caused by the moon.
  • This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.
