How Rocks Wear Away, Read and Answer

Start with something students can look at or think about: a photo, a short video, a jar on the windowsill, or a question like "what do you already know about erosion?" Then let them work through it independently, using a partner or small group only if they want to talk through their thinking, keeping a word bank or anchor chart in view so the vocabulary stays available. When you review, ask students how they knew, and let them point to the part of the diagram or reading that told them. These erosion worksheets work well as a lead in before an investigation, as a way to capture what students noticed afterward, or as review before an assessment.

Read about weathering and erosion and answer 5 questions on how rocks wear away. Earth's surface changes all the time. Water, wind, ice and plants slowly break rocks apart and move the pieces to new places. The directions on the page read: Read about how rocks wear away. Then, turn the page to answer the questions. On page 2: Use the reading on page 1. Circle the letter of the best answer. Then, write the answers on the lines. The answer key covers the questions on page 2.

Yes, both. We made it for 3rd Grade Earth science, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with erosion. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Erosion teaches students that Earth's surface is constantly being changed by natural forces, water, wind, ice, and gravity, that carry rock and soil from one place to another. Third graders learn to distinguish erosion (the wearing away) from deposition (the dropping off) and identify real-world examples like river valleys and sand dunes. It builds understanding of slow Earth processes that operate over very long time scales.

Erosion is typically covered in Grade 3 earth science as part of a unit on Earth's changing surface, often alongside rocks and minerals, volcanoes, and earthquakes. At ages 8-9, students can grasp the idea that small forces acting over long periods create dramatic landscape changes. The concept pairs well with hands-on investigations using sand, water, and trays.

Try a simple at-home erosion demo: pour water slowly over a pile of dirt or sand in a tray and let your child describe what happens using the vocabulary from the worksheet. The diagram activities and real-photo examples in the worksheets make it easy to connect the science to landscapes your child has seen on trips or in books. Even a five-minute outdoor observation, looking at how water has shaped a nearby stream bank, brings the concept alive.

1 printable worksheet, free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 3rd Grade students, roughly ages 8-9. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Each one shows the NGSS code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
