What is the primary source of ions in glacial meltwater?

  1. Atmospheric deposition

  2. Mineral weathering

  3. Biological activity

  4. All of the above


Correct Option: D
Explanation:

Glacial meltwater can contain ions from atmospheric deposition, mineral weathering, and biological activity.

Which of the following ions is typically the most abundant in glacial meltwater?

  1. Calcium

  2. Magnesium

  3. Sodium

  4. Potassium


Correct Option: A
Explanation:

Calcium is typically the most abundant ion in glacial meltwater due to the weathering of carbonate minerals.

What is the process by which ions are released from minerals into glacial meltwater?

  1. Weathering

  2. Erosion

  3. Deposition

  4. Sublimation


Correct Option: A
Explanation:

Weathering is the process by which ions are released from minerals into glacial meltwater.

Which of the following factors can influence the chemical composition of glacial meltwater?

  1. Temperature

  2. pH

  3. Rock type

  4. All of the above


Correct Option: D
Explanation:

Temperature, pH, and rock type can all influence the chemical composition of glacial meltwater.

What is the term for the process by which ions are removed from glacial meltwater?

  1. Precipitation

  2. Evaporation

  3. Adsorption

  4. Ion exchange


Correct Option: A
Explanation:

Precipitation is the process by which ions are removed from glacial meltwater.

Which of the following ions is typically the least abundant in glacial meltwater?

  1. Chloride

  2. Sulfate

  3. Nitrate

  4. Bicarbonate


Correct Option: C
Explanation:

Nitrate is typically the least abundant ion in glacial meltwater due to its low solubility.

What is the term for the process by which ions are exchanged between glacial meltwater and the surrounding rock?

  1. Weathering

  2. Erosion

  3. Deposition

  4. Ion exchange


Correct Option: D
Explanation:

Ion exchange is the process by which ions are exchanged between glacial meltwater and the surrounding rock.

Which of the following ions is typically the most abundant in glacial ice?

  1. Calcium

  2. Magnesium

  3. Sodium

  4. Potassium


Correct Option: C
Explanation:

Sodium is typically the most abundant ion in glacial ice due to its high solubility.

What is the term for the process by which ions are released from glacial ice into glacial meltwater?

  1. Weathering

  2. Erosion

  3. Deposition

  4. Ablation


Correct Option: D
Explanation:

Ablation is the process by which ions are released from glacial ice into glacial meltwater.
