When you get a diagram like this in Describe Image, don’t panic by looking at too many labels. First, quickly look at the main topic. Here, the image is about the structure of the Earth.
You can see the Earth is divided into different layers such as the crust, mantle, outer core and inner core. The image also shows the oceanic crust, continental crust, upper mantle, lower mantle and the Mohorovičić discontinuity.
For PTE, you don’t need to explain every scientific detail. Just speak clearly, connect 3–4 main points, and finish with a simple conclusion.
Sample answer:
The image describes the internal structure of the Earth. It shows different layers, including the crust, mantle, outer core and inner core. It also provides information about the oceanic crust, continental crust, upper mantle and lower mantle. It is clear that the Earth has several layers from the surface to the centre. After analysing this image, it can be concluded that the diagram explains the main parts of the Earth’s structure.
That is how you score in Describe Image.
