How do volcanoes affect the ocean floor?
Volcanoes affect the ocean floor by adding sediment to the ocean basin (bottom of the ocean.) Hope I helped!
Why do scientists look to the ocean floor to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.
What is a description of a shield volcano?
Shield volcanoes ... are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that a a warrior's shield. They are built up slowly by the accretion of thousands of flows of highly fluid basaltic (from basalt, a hard, dense dark volcanic rock) lava that spread widely over great distances, and then cool as thin, gently dipping sheets. Lavas also commonly erupt from vents along fractures (rift zones) that develop on the flanks of the cone. Some of the largest volcanoes in the world are shield volcanoes. In northern California and Oregon, many shield volcanoes have diameters of 3 or 4 miles and heights of 1,500 to 2,000 feet. The Hawaiian Islands are composed of linear chains of these volcanoes including Kilauea and Mauna Loa on the island of Hawaii -- two of the world's most active volcanoes. The floor of the ocean is more than 15,000 feet deep at the bases of the islands. As Mauna Loa, the largest of the shield volcanoes (and also the world's largest active volcano), projects 13,677 feet above sea level, its top is over 28,000 feet above the deep ocean floor.from : http://vulcan.wr.usgs.gov/Glossary/ShieldVolcano/description_shield_volcano.html
Which of these would be indications that a given mountain range was not formed by subduction?
It is not along an ocean coastline. There are no volcanoes.
Why are diatom shells found in ocean-floor sediments?
diatom shells settle on the ocean floor from the surface
What is the size of a shield volcano?
shield volcanos are basalt volcanoes and they are ussaly the smaller of the three tpes of volcanoes starting with rylotic then andesitic then basalt .so you cant put a actuall meausrement on the size of a shiel volcano. Answer #2: The shield volcanoes are produced by the accumulation of basaltic fluid and exhibit the shape of a broad, slightly domed structure that resembles a warrior's shield. Most shield volcanoes have grown from the deep ocean floor to form islands or seamounts. An example of a shield volcano is the Mauna Loa, which is Earth's largest volcano, from its base on the ocean floor of the Pacific Ocean to its summit, Mauna Loa is over 9 kilometers (6 miles) high.
What ocean has volcanoes on its floor?
Pacific Ocean

What ocean floor feature consists of chains of individual volcanoes?
The ocean floor feature that consist of chains of individual volcanoes is called mid ocean ridges. This ridge can rise from 1 to 3 kilometers above the ocean basin.

Can both volcanoes and earthquakes form on the ocean floor?
yes
ARE THERE ANY VOLCANOES UNDER THE ARCTIC?
Yes, on the ocean floor.
What ocean floor feature underwater volcano?
There is an extrmely high amount of underwater volcanoes on pretty much every ocean floor.

What do you think is causing the ocean floor to increase in size?
Sea Floor Spreading and the way the volcanoes erupt make the mountains erode into the ocean.
What is the role of mid ocean ridge in sea floor spreading?
to make volcanoes
