Question 10(1 mark)SavedDeep underground, extreme heat melts rock.Classify what is formed by this process. MagmaIgneous rockSedimentary rock Metamorphic rock

Step 1: Break Down the Problem

We need to classify the geological material formed when extreme heat melts rock underground. The options provided are:

1. Magma
2. Igneous rock
3. Sedimentary rock
4. Metamorphic rock

Step 2: Relevant Concepts

• Magma: Molten rock material beneath the Earth's surface.
• Igneous rock: Rock that is formed from the solidification of molten material (magma or lava).
• Sedimentary rock: Rock that is formed from the accumulation of sediment.
• Metamorphic rock: Rock that is formed from the alteration of existing rock due to heat and pressure.

Step 3: Analysis and Detail

Given the definition of each type of rock:

• When rock is melted due to extreme heat, it becomes molten rock, which is classified as magma.
• If this magma later cools and solidifies, it would then become igneous rock.
• Sedimentary and metamorphic rocks are formed through different processes not directly related to melting.

Step 4: Verify and Summarize

Since the question specifically asks for what is formed by the process of melting, the answer is magma. This is the only term that directly refers to the molten state of rock due to extreme heat.

Final Answer

Magma
