The three factors that affect whether rock melts include temperature, pressure, and the presence of fluids in the rock. Rock melts when the temperature of the rock increases to above the melting point of minerals in the rock.
Q. What is the process by which different minerals melt at different temperatures?
fractional crystallization

Q. When a rock melt different minerals melt at the same temperature?
As a rock heats up, the minerals that melt at the lowest temperatures will melt first. Partial melting occurs when the temperature on a rock is high enough to melt only some of the minerals in the rock. The minerals that will melt will be those that melt at lower temperatures.
Q. Do different minerals melt and crystallize at different temperatures?
Since minerals melt at different temperatures, a rock in which some minerals have melted has undergone partial melting; the opposite process, in which some minerals crystallize out of a magma, is fractional crystallization.
Q. What is the process in which different minerals crystallize from magma at different temperatures removing elements from magma?
2. Extrusive: Fine-grained igneous rock that is formed when molten rock cools quickly and solidifies on Earth’s surface. 3. Fractional crystallization: Process in which different minerals crystallize from magma at different temperatures, removing elements from magma.
Q. What are 3 factors affect the formation of magma?
the formation of magma are temperature, pressure, water content, and mineral content. gradient. increases the rock’s melting point.
Q. What property do all minerals have in common?
Have a characteristic chemical composition – All minerals have a regular chemical composition. Sometimes this composition is made up of just one element, like gold. More commonly, minerals are made of many elements called compounds.
Q. What are four ways to identify one mineral from another?

- METHODS USED TO IDENTIFYING. MINERALS.
- CRYSTALS. One of the best ways to identify a mineral is by examining its crystal form (external shape).
- CLEAVAGE AND FRACTURE.
- COLOR.
- The hardness of a mineral can be measured by its resistance to scratching or abrasion.
- STREAK.
- LUSTER.
- SPECIFIC GRAVITY.
