Final answer:
The photographs show geographical landscapes and natural formations, such as a boreal forest with the Alaska Range and various historical and human-influenced landscapes.
Step-by-step explanation:
The type of features shown in the photographs depict a range of geographical landscapes and natural formations, which are common subjects in geography. For example, a boreal forest consists of a uniform low layer of plants with tall conifers, characteristic of cold, northern climates like that of Alaska. Seeing the snowcapped mountains of the Alaska Range in the background further emphasizes this geographical feature.
Other photographs present different geographical aspects, such as a sea cliff exposure at the Triassic-Jurassic boundary near Lyme Regis, showcasing natural historical transitions, or a landscape depicting the interplay of man and nature, such as an oil pump contrasting with wind power in the background. Each photograph provides a visual aid for studying specific geological or geographical elements, illustrating how diverse the subject of geography can be.
