On a topographical map, an island with an elevation of 80 feet would be represented using contour lines at intervals of 10 feet. You would draw contour lines at 0 feet, 10 feet, 20 feet, 30 feet, 40 feet, 50 feet, 60 feet, 70 feet, and finally at 80 feet. The 80-foot contour line would form a closed loop around the island, indicating its highest point, while the lower contour lines would depict the descending elevation towards the ocean. Any area above sea level would be within the 0-foot contour loop, showcasing the island's topography.
Archipelagos are usually volcanic, forming along island arcs produced by subduction zones (or hot spots). They formed by tectonic activities when a tectonic plate moves over a hot- spot. the lava gets pushed and when there is enough, it rises to the surface of the water. as it cools it forms a pile (an island). the volcanic activity then stops but the plate carries on moving. so when it starts again, a new island is formed.... There are other processes involved in their construction: erosion, deposition and land elevation.
Long Island
Lihue has a smaller annual temperature range compared to Oakland because of the influece of land-water contrast. The island of Lihue is more within the equator belt than Oakland, but is affected heavily by the ocean waters that surround it. The transference of temperature is a constant due to the ocean current throughout the year. There is no large land mass nearby that can affect the climate of the island. Oakland thus get affected by the continental winds and the ocean current that bring cooler waters from the north. Even though both places are affected by the same ocean current, it is significantly higher on the coast due to the topographical features to the east and the cool waters brought down the coast.
Skull Island
No, it is not. It is a noun for an actual island (land surrounded by water) or a figurative one. It is, however, used as a noun adjunct in terms such as island hopping or island paradise.
To show an island with an elevation of 80 feet on a map with a contour interval of 10 feet, you would need to represent two contour lines: one at 80 feet and another at 90 feet. The space between the lines would then indicate the slope of the island's terrain.
To represent an island with an elevation of 80 feet on a topographic map with a contour interval of 10 feet, you would draw contour lines at intervals of 10 feet, starting from sea level (0 feet) up to 80 feet. This means you would have contour lines at 10, 20, 30, 40, 50, 60, 70, and 80 feet, with the highest line being at 80 feet. The 80-foot contour line would enclose the area of the island, indicating that all points within this line are at or above that elevation. Additionally, the contour lines would form closed loops, indicating the island's shape and elevation gradient.
You would just add 10 every contour line you pass until you get to the number 80.

A contour line every 20 feet would be needed to show the island's elevation of 125 feet. This means there would be five contour lines: one at sea level, then at 20, 40, 60, 80, 100, and 120 feet.
Not all topographic maps need a contour line that represents sea level because on some topographic maps you can analyze, that the contour line does not start on sea level. There are several reasons for this. One reason maybe that, the mountain or hill is mapped in the middle of an area and not surrounded by water. Zero meters of elevation represents sea level and if it includes 0 meters than that means that land is possibly an island. In other cases, there should be a contour line marked zero, but in some cases there are not.
Rhode Island's lowest elevation is sea level.
The closer the contour lines the steeper the slope.
