Question

6 multiple choice 2 points which of the following is correct about rocks and minerals? aluminum (al) and iron (fe) are the most abundant minerals in earths crust minerals are composed of different types of rocks the terms rocks and minerals are interchangeable and mean the same thing rocks are composed of different types of minerals 7 multiple choice 2 points rocks are classified into three major types based on: mineral composition color three different rock forming processes how fast magma/lava cooled and solidified

Explanation:

• For question 6:
• Aluminum (Al) and iron (Fe) are elements, not minerals. The most abundant minerals in the Earth's crust are feldspars.
• Minerals are the building blocks of rocks, not the other way around.
• Rocks and minerals have distinct definitions. Rocks are aggregates of minerals or mineraloids.
• Rocks are composed of different types of minerals.
• For question 7:
• Rocks are classified into three major types (igneous, sedimentary, and metamorphic) based on three different rock - forming processes. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks form from the accumulation and lithification of sediments. Metamorphic rocks form from the alteration of existing rocks due to heat, pressure, and chemical processes. Mineral composition is more relevant for classifying minerals within a rock type. Color is a very superficial characteristic and not a basis for major rock classification. How fast magma/lava cooled and solidified is a factor in classifying igneous rocks (e.g., into intrusive and extrusive igneous rocks) but not the basis for the three - major - type classification.

Answer:

1. rocks are composed of different types of minerals
2. three different rock forming processes
