Erosion and deposition landform formation is the focus of this Grade 4 Science resource, helping students explain how water, ice, and wind move sediment and how deposition creates recognizable landforms.

Students connect geological processes to visible changes in the landscape while developing cause-and-effect explanations. The resource explores how erosion transports sediment, how deposition shapes valleys, deltas, beaches, and moraines, and how sediment patterns can provide evidence of past environmental changes. It also brings the topic into a human context by examining how human activities can increase soil loss and unwanted sedimentation.

What students work with

The worksheet combines different ways for students to demonstrate their understanding. Students respond to multiple-choice questions, true-or-false statements, short-answer questions, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” feature. These tasks give students opportunities to recognize geological processes, explain relationships, and communicate ideas using evidence from the topic.

What you receive

• Student worksheet focused on erosion, deposition, sediment movement, and landform formation
• Student Notes & Lesson Summary supplement for reinforcing the key learning
• Separate Teacher Guide PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom use

Use this Grade 4 rocks and geological processes worksheet during a science lesson, as guided or independent practice, or as a review activity after teaching erosion and deposition. The notes supplement can support lesson delivery or student review, while the Teacher Guide provides practical prompts for discussion and helps teachers anticipate common mistakes.

The varied response formats also make it possible to move from identifying processes to explaining them. Students can trace how water, ice, and wind contribute to sediment movement, connect deposition with specific landforms, and use cause-and-effect language to describe how environmental conditions and human activity influence sediment patterns.

Ontario Science classroom support

Designed for the stated Ontario framework, this resource keeps the focus on observable geological processes and the relationships between erosion, sediment, deposition, and changing landscapes. It gives teachers a ready-to-use way to reinforce erosion and deposition while giving Grade 4 students multiple opportunities to explain what causes landforms to develop.
