Answer 2

The words to complete the rock cycle are,

(2) Igneous rock

(3) Sediments

(4) Sedimentary rock

(5) Metamorphic rock

Explanation:

• The basic concept in geology is rock cycle and it explains the transition of sedimentary rock, metamorphic rock and igneous rock.
• Magma is created when the temperature gets hot and igneous rock is formed when magma is cooled.
• When magma gets cooled slowly, the crystal will grow larger and vice versa.
• The process of forming crystals from magma is called crystallization.
• Water, wind, ice can break the rocks into sediments.
• The process of breaking down the rock is called weathering.
• The rock pieces are carried by wind, water and glaciers is called erosion.
• Sedimentation is the process of depositing the sediments.
• Sedimentary rocks are formed when sediments are cemented together.
• In the earth crust, if the rock possess high heat and pressure, then it undergoes metamorphism.
• Metamorphic rocks are formed due to the excess of heat and pressure.
