Answer

Answer:

  • The slower the cooling, the larger the crystals. The faster the cooling, the smaller the crystals.
  • When a solution cools, elements and compounds leave the solution and crystallize as minerals.
  • Minerals formed from hot water solutions can form narrow channels in the surrounding rock.

Brief Explanations:

  • For the first statement: In mineral formation, slower cooling allows more time for atoms to arrange into larger crystals, while fast cooling limits this, so this statement is true.
  • For the second statement: Magma cools more slowly (as it is underground) than lava (which is on the surface and cools quickly). So crystals from magma are larger than those from lava. This statement is false.
  • For the third statement: Minerals can form in solutions when the solution evaporates (not just when heated). For example, salt (a mineral) forms when seawater evaporates. So this statement is false.
  • For the fourth statement: As a solution cools, its capacity to hold dissolved elements and compounds decreases. So these substances precipitate out and crystallize as minerals. This statement is true.
  • For the fifth statement: Hot - water solutions (hydrothermal solutions) can deposit minerals in fractures and voids in rocks, creating narrow channels (veins) filled with minerals. This statement is true.
