Question

Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth's crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.

Answer 1

The journey of an igneous rock through the rock cycle includes weathering, erosion, deposition, sedimentary rock formation, metamorphism, melting, and the formation of new igneous rock.

Step-by-step explanation:

The Rock Cycle: When considering an igneous rock at the top of a mountain, its journey through the rock cycle would include several steps. However, the steps provided need to be reordered to correctly represent the cycle:

1. Rock is broken down into regolith by weathering.
2. Regolith is transported or eroded by rain or wind.
3. Regolith is dumped into some type of reservoir, usually water, by deposition.
4. Layers deposited begin to compact and cement together to form sedimentary rock.
5. Sedimentary rock is buried deeper into the earth's crust. The intense heat and pressure begins metamorphism, and the rock turns into metamorphic rock.
6. Metamorphic rock begins to melt back into magma.
7. Magma is resurfaced from volcanic activity, cools, and becomes new igneous rock.

This sequence outlines the transformation of an igneous rock into sedimentary and metamorphic rocks, and eventually back into a new form of igneous rock, thus completing the cycle.

Answer 2

The correct sequence according to the question is steps- 4→1→3→5→6→2→7.

Step-by-step explanation:

The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as the rock cycle.

The steps of the rock cycle in sequence according to the question are:

1. Breakdown of rock by weathering into regolith- step 4

2. Dumping and deposition of regolith in a reservoir- step 1

3. Erosion and transportation of regolith by rain or wind- step 3

4. Cementing of the deposited layer to form sedimentary rock- step 5

5. Conversion of sedimentary rock to a metamorphic rock due to intense heat and pressure- step 6

6. Conversion of metamorphic rocks to magma due to the melting of metamorphic rocks- step 2

7. Conversion of magma to igneous rocks due to volcanic activities and cooling of magma- step 7

Therefore sequence according to the question is steps- 4→1→3→5→6→2→7 is correct.
