Which statement BEST describes how the Okefenokee Basin may have been formed?
The Okefenokee Basin may have been formed through a combination of tectonic processes, such as the shifting of tectonic plates, and the accumulation of organic material over millions of years. The basin's low-lying characteristics and wetland ecosystems suggest a history of gradual subsidence and sediment deposition.
What is the portion of the ocean floor that is made up of oceanic crust?
Approximately 60% of the ocean floor is made up of oceanic crust. Oceanic crust is typically thinner and denser than continental crust, and it forms at mid-ocean ridges through volcanic activity.
Which basin contains many deep sea trenches?
The Pacific Ocean basin contains many deep-sea trenches, such as the Mariana Trench, which is the deepest known point in the ocean. These trenches are formed by the subduction of tectonic plates, creating some of the most extreme environments on Earth.
How do volcanoes affect the ocean floor?
Volcanic eruptions on the ocean floor can create underwater mountains, known as seamounts. These eruptions also release gases and minerals, which can support unique ecosystems around hydrothermal vents. Additionally, volcanic activity can trigger tsunamis that impact coastlines.
How do strip of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
How was the okefenokee basin formed?
The Okefenokee Basin may have been formed when a bay of the Atlantic Ocean was cut off from the ocean by a barrier island.
What are the three regions of the ocean floor?
the continental Margin, Ocean Basin Floor and Mid-Ocean ridge :D
What is the scientific name for the ocean floor?
Abyssal Plain.
What are the three main regions of the ocean floor?
the continental Margin, Ocean Basin Floor and Mid-Ocean ridge :D
What are the Maine three region of the ocean floor?
the continental Margin, Ocean Basin Floor and Mid-Ocean ridge :D
How the Okefenokee Basin may have been formed?
The Okefenokee Basin may have been formed when a bay of the Atlantic Ocean was cut off from the ocean by a barrier island.
Name two major regions of the ocean floor?
continental margin deep-ocean basin
Is a mid ocean ridge a long narrow depression located in a deep ocean basin?
No. A mid-ocean ridge is a chain of mountains and volcanoes in an ocean basin at a site of sea floor spreading.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Is the mid ocean ridge the location of the oldest ocean floor?
No, the mid-ocean ridge is actually where new oceanic crust is formed through volcanic activity. As the crust moves away from the ridge, it becomes older. The oldest oceanic crust is found near the edges of the ocean basins.
Volcanic mountains scattered along the ocean basin are?
Seamounts are isolated volcanic mountains scatteredacross the ocean floor
What are the flat-topped volcanic structures located on the floor of the deep ocean basin?
seamounts
