on the planet.

Where is the largest percentage of the world ocean found? correct answers southern hemisphere

How old is the Earth? correct answers 4.543 billion years

What causes the Earth's magnetic field? correct answers hot spinning liquids.
This flow of liquid iron generates electric currents, which in turn produce magnetic fields.

How do oceanic trenches form? correct answers plate sinks beneath another plate.
Earth's tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and
deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form
a steep, V-shaped depression.

What is the continental shelf and where is it located? correct answers shallow part of the
continent, close to land where light can reach it

What is the mid-ocean ridge? correct answers an undersea mountain chain where new ocean
floor is produced at a divurgent plate boundary

submarine mountains that run through the marine basin

What is it called when new seafloor is created? correct answers seafloor spreading.

formed through volcanic activity and then gradually moves away from the ridge.
