The rock cycle worksheet for Grade 6 Science explores how igneous, sedimentary, and metamorphic rocks form and change through different geological processes. Rather than treating the rock cycle as one fixed sequence, students investigate how weathering, erosion, deposition, compaction, cementation, heat, pressure, and melting create multiple possible pathways between rock types.

Written for the Texas Science 6 topic Earth Systems, Space Cycles and Resources, this resource introduces the processes behind rock formation through a focused reading passage. Students learn that igneous rocks form when magma or lava cools and solidifies, sedimentary rocks develop as sediments become compacted and cemented, and metamorphic rocks form when existing rocks change under heat and pressure without completely melting.

Follow the processes, not just the rock names

A central idea in this Earth science resource is that the rock cycle has no single required order. An igneous rock may weather into fragments, undergo erosion and deposition, and eventually become sedimentary rock. A sedimentary rock may change into metamorphic rock under heat and pressure, while melting followed by cooling can produce igneous rock from previously existing material.

Students connect each process to its role in changing Earth's materials. They distinguish weathering, which breaks rock into smaller pieces, from erosion, which transports those pieces. They also examine deposition, compaction, and cementation as parts of sedimentary rock formation, and consider how underground heat and pressure affect existing rocks.

Activities that build geological reasoning

• Multiple-choice questions: Identify rock-forming processes, distinguish weathering from erosion, interpret possible rock-cycle sequences, and apply knowledge of heat, pressure, melting, and cooling.
• True-or-false statements: Evaluate claims about rock formation, sedimentary processes, erosion, and the misconception that every rock follows the same sequence.
• Short-answer questions: Describe a pathway from igneous to sedimentary rock, explain the conditions for metamorphic rock formation, and compare different possible pathways.
• Labeled diagram and categorization activities: Extend learning through visual and classification tasks related to the lesson.
• Short-note section: Provides space for additional lesson notes.

Materials for students and teacher

• Printable Grade 6 Science worksheet with a reading passage and rock-cycle practice.
• Student Notes lines at the bottom of the worksheet.
• Separate PDF answer key for checking student responses.
• Teacher Guide within the answer key PDF, including Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Bring the rock cycle into your Earth science unit

Use the passage to introduce rock formation, assign the activities for independent practice, or revisit the topic during a unit on Earth's systems and resources. The pathway questions are particularly useful for checking whether students can explain how one rock type may change into another by naming the processes involved, rather than simply memorizing rock names.

This Grade 6 rock cycle practice combines key geological vocabulary with process-based explanations and alternative pathways. The separate answer key supports checking, while the teacher guide provides additional instructional prompts for discussing misconceptions and strengthening students' explanations of how rocks change over time.
