Weathering and erosion become easier to explore when Grade 4 science students connect real changes on Earth's surface with the main ideas and supporting details in informational text. This reading organizer resource focuses on how running water, plant roots, wind, glaciers, and ocean waves break down rock, move sediment, and gradually reshape landscapes.

Explore How Earth's Surface Changes

Students read about distinct weathering and erosion processes through familiar landforms and observable changes. River passages connect flowing water with rock fragments, river valleys, and deltas. A plant-root passage explains how growing roots widen cracks and help break rock apart. Wind examples show how sand moves, gathers behind obstacles, and contributes to migrating dunes. Glacier reading introduces bedrock scratches called glacial striations, transported rock, and sediment left behind when ice melts. Coastal cliff reading explores how waves loosen rock, scrape cliff faces with sand and pebbles, and gradually move cliff edges inland.

Read, Highlight, and Organize Evidence

Each reading activity pairs a short informational passage with a main idea and supporting details organizer. Students identify the sentence that communicates the passage's central message, highlight supporting information, and restate the main idea and relevant details in their own words. This gives learners focused practice with informational text while reinforcing science vocabulary and cause-and-effect relationships.

• Distinguish a passage's main idea from supporting facts.
• Connect weathering agents to the changes they cause in rocks and landscapes.
• Identify details about river valleys, deltas, plant-root weathering, sand dune movement, glacial striations, and coastal cliff retreat.
• Use evidence from informational passages to explain how Earth's surface changes over time.

What the Resource Includes

• Informational reading passages about different weathering and erosion processes.
• A main idea and supporting details organizer for each passage.
• Suggested main idea and supporting detail answers to support checking and review.
• Picture plans connected to the specific landforms, rocks, plants, ice, sand, and water described in the readings.

Ways to Use It in Grade 4 Science

Use this weathering processes reading practice during an Earth science unit, as independent literacy-connected science work, or for small-group reading support. Students can read one passage, highlight its central message and evidence, and complete the organizer before discussing how different natural forces change land at different rates. The focused passages also provide a way to revisit vocabulary such as sediment, delta, erosion, and glacial striations in context.

By pairing reading comprehension with concrete examples of landscape change, this resource helps students organize scientific information rather than simply memorize terms. Teachers can use the completed organizers to review students' ability to identify central ideas and select details that accurately support them.
