Deep ocean sediments are thickest where the underlying crust is?
oldest
Are maps made from sonar and magnetometer data led to the discovery of ocean ridges and deep-sea trenches?
no they found ocean ridges sonar maps alone found deep-sea trenches
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
Two primary types of sediments on ocean bottom?
There are two types of deep ocean sediments, abyssal clay and biogenous oozes. Abyssal clays are fine-grained sediment, while biogenous ooze is composed of the hard parts of microscopic organisms.
Chalk formed from sediments made of skeletons of microscopic living things in the ocean must be a?
Chalk formed from sediments made of skeletions of microscopic living things in the ocean must be a(n) organic rock.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
because that there are younger rocks found at ocean ridges than the ones found near deep-sea trenches
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
Deep ocean sediments are thickest where the underlying crust is?
oldest
Are maps made from sonar and magnetometer data led to the discovery of ocean ridges and deep-sea trenches?
no they found ocean ridges sonar maps alone found deep-sea trenches
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
What does deep-ocean basin consist of?
the deep ocean basin consist of the deepest part of the ocean . :)
How are ridges formed on the ocean floor?
Ocean current paths of travel, underwater volcanoes, tectonic plate movement, depends which specific ridges you are talking about.
Deep ocean sediments is associated with which of the bioeochemical cycles?
Phosphorus Cycle
Deep ocean sediments is associated with what biogeochemical cycles?
Phosphorus cycle
Deep ocean sediments is associated with which of the biogeochemical cycles?
phosphorus cycle
What do mid-ocean ridges transfer heat energy from?
Mid-ocean ridges transfer energy from the mantle/asthenosphere/lithosphere to the surface. The energy is from the deep Earth.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
