Question

MGS and later orbiters found spectral evidence for what minerals on the Martian surface? Check all that apply.

Answer 1

Mars Global Surveyors (MGS) and later orbiters found the following  minerals on the  Martian surface;

• Phyllosilicates

• Carbonate
• Sulfates
• Iron oxide

The Mars Global Surveyors (MGS) and later orbiters suggest that the Martian crust contains a higher percentage of volatile elements such as Sulphur and chlorine than the Earth's crust does.

These scientists also conclude that the most abundant chemical elements  in the Martian crust are those found in Igneous rock.

These elements include the following;

• Silicon,
• Oxygen,
• Iron,
• Magnesium,
• Aluminum,
• Calcium, and
• Potassium.

They also, suggest that hydrogen is found in ice (water) while carbon is found in carbon dioxide and carbonates.

From the given options the minerals found in Martian surface include;

• Phyllosilicates ------ these are sheet of silicate minerals

• Carbonate
• Sulfates
• iron oxide
