What else can I help you with?
Is the Rock found at mid ocean ridge old or young?
yes young rocks are found at mid ocean ridges not old rocks.
What is a mountainous chain of young basaltic rock at the active spreading center of an ocean?
an oceanic ridge
Is weathering of rock on the coastline one source of the salt that has been dissolved into the ocean?
Yes that's true.
Why are the Rock's close to a mid-ocean ridge younger than the ones that are farther away?
Mid-ocean ridges are basically underground volcanoes that lava from the Earth's Mantle can breach. The ocean, however, freezes the lava and that in turn forms rock. If this happens repeatedly, then the older rock gets pushed away from the source, and the younger, just formed rock is, therefore, closer to the ridge. So the younger rock being formed by the ridge is pushing away the older, previously made, igneous rock.
What affects the age of the ocean floor?
The distance and rate at which they are growing from "mid-ocean ridges" from which molten rock (magma) rises from the Earth's mantle. Younger rock is closest to these ridges while older rock is further. The old rock will eventually be recycled into the mantle via a process known as "subduction", marked by trenches in the ocean floor. - source: Essentials of Geology 3rd Edition (Marshak, 42)
What is the name of the rock beneath the ocean called?
the rock beneath the ocean is basalt
Main source of carbon dioxide in the ocean?
the atmosphere is the main source of CO2 in the ocean
What type of rock is organic rock?
An Organic rock is an Sedimentary rock and it is made in the ocean from calcium and other minerals building up on the ocean floor :)
Are earthquakes a source of ocean salts?
yes earthquakes are a source of ocean salts by the great shake
