Which ocean floor feature is responsible for creating new land?

Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ridge push. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed. Hydrothermal vents are common at spreading centers.

What type of feature makes up most of the ocean floor?

The smooth, flat regions that make up 40% of the ocean floor are the abyssal plain. Running through all the world’s oceans is a continuous mountain range, called the mid-ocean ridge(“submarine ridge” in Figure 14.23).

What creates the mountains and sea floor in the ocean?

It is here that new ocean floor is continuously created. As the two sides of the mountain move away from each other, magma wells up from the Earth’s interior. It then solidifies into rock as it is cooled by the sea, creating new ocean floor.

What is the warm top layer of ocean water?

epipelagic zone

Is the first step of seafloor spreading?

A crack forms in oceanic crust. Molten rock rises up through oceanic crust. Molten rock solidifies at the center of the ridge.

What are the three steps to create new ocean floor?

  1. convergent boundary — plates converge, or come together.
  2. divergent boundary — two plates diverge, or move apart and new crust or lithosphere is formed.
  3. transform fault boundary — plates slide past one another with no creation or destruction of lithosphere.

What is ocean floor configuration?

Ocean Floor Configuration An oceanic basin is the land surface under an ocean that includes the topography under the water. The ocean floors can be divided into four major divisions: The Continental Shelf. The Continental Slope.

Are oceans dark?

Pure water is perfectly clear, of course — but if there is a lot of water, and the water is very deep so that there are no reflections off the sea floor, the water appears as a very dark navy blue. The reason the ocean is blue is due to the absorption and scattering of light.

Why is ocean so dark?

In very deep water, almost all of the sun’s rays are absorbed by the water itself due to the lack of sediment and the lower amount of organic matter (like algae and jellyfish), and thus the blue appears to be darker.

Why is tropical water so clear?

Coral reefs act as a barrier to break up moving water. This results in calmer water near the shore that is free from sediments and nutrients, giving the water a clear appearance. Another reason the water appears clear is that it is free from algae.
