Solution
Solution Steps
Step 1: Identify Oceanic Crust Characteristics
Oceanic crust is typically found under the ocean and is denser and thinner than continental crust. It is usually represented by darker blue colors in topographic maps.
Step 2: Analyze the Map
Examine the color-coded topographic map. The darker blue areas represent deeper oceanic regions, which are indicative of oceanic crust.
Step 3: Determine Locations on Oceanic Crust
Site D: Located in a dark blue area, indicating deep oceanic crust.
Site B: Located near the boundary between oceanic and continental crust, but still within the darker blue region.
Site A: Located in a lighter blue/green area, indicating shallower waters or continental shelf, not typical of oceanic crust.
Site C: Located in a lighter blue area, indicating shallower waters or continental shelf, not typical of oceanic crust.
