Describe the Topography of the Seafloor

Shelf slope canyons rise and abyss. Convergent divergent and transform.

18 1 The Topography Of The Sea Floor Physical Geology

The surface of the Earth is composed of a mosaic tectonic plates moving with respect to each other.

. 2 Continental slope - The steeply sloping region of the continental margin that extends from the continental shelf. Sharp edge to basin. This can be seen in the highest of the underwater features.

What are conditions like on the seafloor. The Earth is made of seven major plates and several smaller plates. It starts with the Outer Continental Shelf followed by the Continental Slopes and subsequently the Ocean Floor.

Earth Revealed Episode 4. Ocean Floor Topography the study of numerous landforms that exist on or below the earth. Sound waves that bounce off the bottom and back up.

Shelve narrow as 2 kilometers. Shelf slope canyons rise and abyss. The mid-ocean ridge is the highest.

Describe the topography of the seafloor. 181 The Topography of the Sea Floor Physical Geology nd The deepest parts of the ocean are within the subduction trenches and the deepest of these is the Marianas Trench in the southwestern Pacific near Guam at 11000 m. The geographic north pole is located over the floor of the Fram Basin near its juncture with the Lomonosov Ridge.

1 Continental shelf - The gently sloping region of the continental margin that extends seaward from the shoreline to. The ocean floor slopes steeply down to the ocean basin or abyssal plain. It is a locus of active ocean-floor spreading with a well-developed rift valley and flanking rift mountains.

It is the place where the magma comes out cools off and constantly creates new rocks or rather crust. In a nutshell sea floor topography is the study or mapping of geologic features at the bottom of the sea. The landscape of the ocean floor is much like what you see on land just way more dramatic and without all that life.

Canyons is between shelf and rise. Covers 16 of earths surface. What do oceanic ridge systems represent.

The Fram Basin lies between the Nansen-Gakkel Ridge and the Lomonosov Ridge at a depth of 14070 feet. Solution for How would you describe the topography of the ocean floor generally flat or variable in depth when incoming waves to a straight shoreline bent. The plates form three different kinds of boundaries.

Sonar sound navigation and ranging is a tool used to map the ocean floor. Refers to the different forms in which the ocean floor bottom can exist is similar to the ground topography with features such as valleys mountains and plateaus. Of sediment settles on ocean floor.

What are terrigenous and pelagic sediments. As we move further away from the mid-ocean ridge we will. As the plates move new sea floor can be created.

Sonar tells us topography. Into the continental slope and meets the ocean floor. Youll see underwater mountains called seamounts cliffs trenches and abysses.

Describe the four methods we use to explore the topography and rocks of the seafloor sonar submersibles drilling and satellites. Thanks to a new synthesis of seafloor topography released through Google Earth armchair explorers can now view five percent of the deep. Seamounts are underwater peaks with different shaped tops.

The Japan Trench is over 9000 m deep and the Puerto Rico and Chile. What is the main type of igneous rock found on the seafloor. Other trenches in the southwestern Pacific are over 10000 m deep.

The abyssal plain is the flat open plain of the ocean floor. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics. Describe the topography of the seafloor.

The topography of the seafloor gives us a nice clue about the seafloor spreading. The outer rocky layer of the Earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig-saw. What is found at the crest of the.
