What maps show features of the ocean floor?

Contour maps for land are called topographic maps. Contour maps for ocean depths are called bathymetric maps or charts.

What are the key features of the ocean?

Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

What are the 5 features of ocean basins?

Ocean ridges, deep-sea trenches, abyssal hills, fracture zones, seamounts, and guyots are some of the major features of an ocean basin.

What are the features of seafloor spreading?

Seafloor spreading produces major characteristics of the seafloor – 1) the age of the seafloor is progressively older away from midocean ridges, 2) the elevation of the seafloor is progressively lower away from midocean ridges, 3) the magnetic history of the seafloor bears the striped-pattern of the Earth’s magnetic …

Which is one feature of the ocean floor found in the open ocean?

Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots. The basins also contain a variable amount of sedimentary fill that is thinnest on the ocean ridges and usually thickest near the continental margins.

What is the order of ocean floor features between the shore of a continent and the deep ocean floor?

The sea floor below the break is the continental slope. Below the slope is the continental rise, which finally merges into the deep ocean floor, the abyssal plain.

What are 4 features of the ocean?

Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge. The ocean floor is rich in resources. Living things on the ocean floor are used for food or medicines.

What are typical features of deep ocean basins?

Deep-Ocean Basins. Deep-ocean basins cover the greatest portion of the Earth’s surface. Geographic features associated with deep-ocean basins include trenches, abyssal plains, ocean ridges and rises, and submarine mountainous regions.

What does the colored paper represent in seafloor spreading?

oceanic crust
The strips of paper represent oceanic crust or seafloor. 3. The oldest sections should be the sections on both sides furthest from the middle 4. Seafloor spreading is the creation of new seafloor or new oceanic crust 5.

What is the importance of seafloor spreading involving ocean ridges?

Significance. Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere.

What are the features of the ocean floor?

Ocean floor features. 1 Continental shelf. Starting from land, a trip across an ocean basin along the seafloor would begin with crossing the continental shelf. The 2 Abyssal plains. 3 Mid-ocean ridge. 4 Ocean trenches. 5 Plate tectonics and the ocean floor.

What are the characteristics of the ocean water?

For example, warm salt water might float on colder, less salty water. Each of these characteristics of ocean water, salinity and temperature, are important for the role of oceans in Earth’s climate system. Like the heated air in a hot-air balloon, heated water expands.

How do upwells affect the ocean?

Eventually, the cold, dense water “upwells” to the surface bringing many nutrients from the depths up to the surface waters where marine life thrive; this is indicated by productive fishing grounds. This is triggered when winds blow water across the ocean’s surface, allowing deeper water to rise up to replace this displaced surface water.

What is the underwater landscape of the ocean like?

Beneath the smooth ocean surface extends an underwater landscape as complex as anything you might find on land. While the ocean has an average depth of 2.3 miles, the shape and depth of the seafloor is complex. Some features, like canyons and seamounts, might look familiar, while others, such as hydrothermal vents and methane seeps,
