why might a model be uesful for understanding how landform change
If you want to include all geological features, a Yardang(a sharp-crested ridge carved by wind erosion from soft but coherent deposits) might be considered a "landform".
A reader might have trouble understanding a primary source due to unfamiliar language or terminology, lack of context or background knowledge, cultural differences, or bias or subjectivity in the source. Engaging with supplementary materials, seeking out expert analysis, and considering multiple perspectives can help improve understanding.
The most useful method to identify a rock is through its mineral composition, as different minerals have distinct properties that can help in classification. The least useful method might be color alone, as many rocks can have similar colors but different compositions. Other properties like hardness, texture, and structure can also be helpful in identification.
A landform created by tectonic forces, such as a mountain range or a rift valley, would have more pronounced and angular features due to the intense geological pressures and forces involved. On the other hand, a landform created by a glacier, like a U-shaped valley or a fjord, would have smoother, rounded contours as the glacier slowly erodes and shapes the landscape over time with its movement and weight.
Fossils are more useful than rock types in correlating rock layers on different continents because they provide direct evidence of ancient life forms that can be compared and matched across continents. Fossils can also help determine the relative ages of rock layers, which is crucial for understanding the timing and sequence of events in Earth's history. In contrast, rock types can vary widely between continents, making direct correlations more challenging.

Understanding how to read food labels might benefit you by allowing you to get a better idea of what you are putting into your body, and whaat nutrition you can actually get from the packaged foods you consume. This is especially useful if you are unsure as to what an actual portion size of something is.

A question may appear and you might know the answer to it. Now, I'm not saying it's important to learn everything, but learning\understanding some general knowledge is quite useful.

You could find a sand clump out in the water a little way, which is called a sandbar.
To determine if a resource might be useful, you will need to evaluate the information in the resource and decide if it is valid, useful, accurate, reliable, and relevant. You should also check the date of publication.
Gases are useful for lots of things. you might need to specify on what gas it is?
because we did it
A preposition that comes after useful might include for, except, during, and inside.
