How do scientists know the Earth has layers?

• Drilling into the mantle

• Volcanoes

• Seismic waves data

• ocean waves

What is the difference between the lithosphere and asthenosphere that makes up the mantle?

• The lithosphere is ismade of dense solid meal whle the asthenosphere is made of liquid molten metal

• The lithosphere is a mixture of gasses while the asthenosphere is made of solid rock

• The lithosphere is molten rock that moves while the asthenosphere is ridid and thin

• The lithosphere is made of solid rock while the asthenosphere is more flexible hot rock that moves.

What is the difference between the lithosphere and asthenosphere that makes up the mantle?

• The lithosphere is made of dense solid metal while the asthenosphere is made of liquid molten metal

• The lithosphere is a mixture of gases while the asthenosphere is made of solid rock

• The lithosphere is molten rock that moves while the asthenosphere is rigid and thin

• The lithosphere is made of solid rock while the asthenosphere is more flexible hot rock that moves.

Answer explanation

The lithosphere is made of solid rock, providing a rigid outer layer of the Earth, while the asthenosphere consists of more flexible, hot rock that can flow, allowing for tectonic movement.

Match the following part of Earth's interior with the correct definition.

• inner core

• dense basaltic rock layer

• outer core

• semi-solid large volume layer

• continental crust

• liquid iron, nickel, and cobalt

• mantle

• dense solid sphere of iron, nickel, and cobalt

• oceanic crust

• Lowest density layer of earth made of a granite core

The ​ (a)   is layer of Earth's interior that is inferred to be composed of solid iron and nickel.

• Inner Core

• Mantle

• Asthenosphere

• Outer Core

The formation of magma is a process driven by energy from _____________.

• the sun

• Earth's interior

Answer explanation

Earth's interior is extremely hot due to the heat from the inner core. This heat causes the mantle to be hot enough to melt rock into magma.

What is the difference between the lithosphere and the asthenosphere that makes up the mantle?

• The lithosphere is made of dense solid metal while the asthenosphere is made of liquid molten metal

• The lithosphere is a mixture of gases while the asthenosphere is made of solid rock

• The lithosphere is molten rock that moves while the asthenosphere is rigid and thin

• The lithosphere is made of solid rock while the asthenosphere is hotter, more flexible rock that moves.
