The diagram shows the formation of supervolcano and the stages involved. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
The diagram shows the steps of how a supervolcano forms.Overall, the process starts with magma building up under the ground, continues with an eruption, and ends with the ground sinking to form a large hole.
The process begins deep underground, where magma collects in a large space called a magma chamber. As more magma fills the chamber, the pressure becomes very strong. This pressure causes cracks in the Earth’s crust, and magma starts to rise through the cracks. When the magma escapes, it causes a big eruption. The eruption sends out smoke, ash, and lava, which change the land. In short, a supervolcano forms when magma builds up, erupts, and ends with a large hole on the surface.
The essay follows a logical sequence but lacks detailed linkage between stages.
Suggestions
- Use more linking words to connect stages.
- Include comparisons where relevant.
- Clarify the transition between stages.
Vocabulary is adequate but lacks variety and precision.
Grammar is generally accurate but lacks complexity.
The essay summarizes the process but lacks detailed comparisons and specific terminology.
Suggestions
- Include more specific terms like ‘caldera’ and ‘fissure.’
- Make comparisons between different stages.
- Provide more detail on each stage.
