Hi! I am Studyfin, your science buddy. Today, we will learn how nature shapes our amazing Earth!
Earth is always changing. Rocks break down into smaller pieces, and then those pieces move to new places.
First, weathering breaks rocks. Water, wind, and ice act like tiny hammers. They crack big rocks into small bits of dirt and sand.
Next, erosion moves the broken rock pieces. Wind and water carry the sandy bits away to new spots.
Authors write about science in special ways. In this lesson, we look at how authors use a cause and effect structure. This helps us see how weathering causes erosion.
Read this short paragraph: 'Heavy rain pours down on a dirt hill. The strong water breaks the hard soil into tiny mud bits. Then, the rushing water washes the mud down the hill.' Let us explain how the author's use of cause and effect text structure helps us understand Earth changes.
- Find the first event. The heavy rain pours on the dirt hill.
- Identify the cause. The water breaks the soil into mud. This is weathering.
- Identify the effect. The rushing water washes the mud away. This is erosion.
- Explain the author's purpose. The author uses this cause and effect structure to show that weathering must happen first so that erosion can follow.
