It is expensive to mine minerals from deep-water deposists than from continental shelf deposits true or false?

It is not less expensive. Deepwater operations take considerably more money. Multiple contractors and firms have to come together to overcome vast depths. The added risks involved also mean more costs.

Flat seafloor in the deep ocean formed when deposits of sediment filled valleys?
continental slope
Which portion of the ocean floor is rich in mineral deposits that are sometimes mined and drilled?
continental shelf
Were do the thickest deposits of terrigenous sediment typically form?
continental margins near the mouths of rivers now stop cheating on novanet
How do glacial deposits support the idea of continental drift?
With continents in their present positions, the till deposits do indicate erratic glacier motion. When continents are fitted together, they show much more streamlined motion of the glacier from the southern Africa and the Northern Australia outward.
What experiments did Alfred wegener use to surrport his idea on continental dift?
He investigated rock layer deposits in Greenland and Norway looking for matches that would show common history.
How many petroleum deposists are in Maine?
Maine does not have any oil deposits-well, at least no discovered oil deposits.

How do the ages of the oldest sediments compare to the ages of the oldest continental rocks?
The oldest continental plate rocks will always be older than the oldest sedimentary deposits.

Are geosynclines in the sea or on land?
A geosyncline is a belt of sedimentary deposits that accumulate within the ocean along the margin of a continent - on the continental shelf and slope.
How do glacial deposits support the idea of continental drift?
With continents in their present positions, the till deposits do indicate erratic glacier motion. When continents are fitted together, they show much more streamlined motion of the glacier from the southern Africa and the Northern Australia outward.
where is the continental crust?
Below your feet as you read this - unless you're on board a ship on the ocean! The Continental Crust is the foundation rock for the continents, and is usually covered to a greater of less depths by sedimentary rocks and drift deposits. In turn it floats on the Aesthenosphere, the outer layer of the Mantle.
