Why is there less silica in ocean water than river and ground water?
almost no silica in ocean water but most of its the earths crust.
What is older the continents or the ocean floor?
On average, continents are older than ocean basins. Due to the action of plate tectonics, ocean crust is being formed and destroyed continuously. The oldest oceanic crust is about 200 million years old, whereas continents, which are less dense than oceanic crust and tend not to be subducted into the mantle, can be more than 3,000 million years old in places.
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
Why the crust is thinner than the ocean floor?
The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
What evidence proved the ocean floor was moving?
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
Does the earths crust extend deeper below the continents or below the ocean basins?
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
Why is there less silica in ocean water than river and ground water?
almost no silica in ocean water but most of its the earths crust.

Is oceanic crust near a mid ocean ridge older than oceanic crust far away?
Sorry, you have it entirely reversed.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.

The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
How do the ages of the rocks making up continents and those making up the ocean bottom differ?
Continental crust is normally much older than oceanic crust.
How do the sediments on the ocean floor vary in relation to an ocean ridge?
Sediments become thicker away from the mid ocean ridge. This is because the oceanic crust away from the mid ocean ridge is older than the crust close to it, so sediment has had more time to accumulate.
