What mechanical layer lies below the lithosphere

asthenosphere

What happens during subduction

Dense oceanic crust slides under less dense continental crust

A fault generally occurs at a transform boundary

A strike-slip fault generally occurs at a transform boundary

What keeps the inner core in a solid state

high pressure

What causes the pressure that allows diamonds to form in the mantle

The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.

When a seismic wave crosses a boundary it will change directions in the process of

refraction

Why can diamonds form in the mantle

The weight of the rocks above the mantle results in high pressure.
Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.

There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.

What factor is responsible for keeping the inner core in a solid state

high presure and heat

What is a true statement about the magnetic field between two magnets

The south pole of one magnet is attracted to the north pole of the other magnet.

What is true about compasses

compass magnets can be deflected by earths magnetic field or other permanent magnets

Most deformable layer of the Earth

mantle

The continental crust is what

The continental crust is up to 70 km thick.

Which Match each moon and planet to the most accurate characteristic

earth moon

New crust forms

At ocean ridges

Which of the following is true of permanent magnets

magnetic stuff...
