Hi! Let's see how authors organize words to teach us about rocks and minerals.
Authors use text structures to organize ideas. Cause and effect is one type of text structure. It shows why something happens.
Heat and pressure melt rock deep underground. This cause leads to a liquid called magma. When magma cools, hard rock forms.
The author uses cause and effect to help us learn. It explains how heat creates new rocks. This structure makes the science cycle clear.
✏️ Worked example
Read this text: 'Water gets into rock cracks. The water freezes and expands. This causes the rock to break apart.' How does the author's choice of text structure help the reader?
Find signal words. The word 'causes' shows a cause and effect structure.
Identify the cause. Water freezes and gets bigger inside the crack.
Identify the effect. The rock splits and breaks into pieces.
Explain the purpose. This structure helps me understand how ice breaks rock.
