This is the thin and solid outermost layer of Earth

Crust

This layer is liquid metal

Outer Core

Outer part is solid & rigid, but becomes soft and easily deformed

Mantle

This layer is solid metal

Inner Core

This is the term used to describe the plastic-like part of the Earth

asthenosphere

This is the name for the supercontinent that existed 300 million years ago

Pangaea

This was the scientist who proposed the Theory of Continental Drift

Alfred Wegener

Africa & South America are the best example for this piece of evidence

Geysers

This is made up of the crust and upper portion of the mantle.

Lithosphere

S-waves

These waves can only travel through solids.

Surface waves or S- Waves

P-waves are also known as this.

Longitudinal waves

This is the exact point where an earthquake originates

Focus

Seismic waves slow down once they reach this layer of the Earth

Outer Core

These are the two ways that thermal energy is transferred through Earth

Conduction and Convection

When 2 lithospheric plates move apart, it is called this type of boundary

Divergent boundary

Name 2 items that form at a divergent boundary

Rift Valley, Ocean Ridge, Volcano, or New Sea Floor

This is why fossils are good indicators of relative age

They occur for well defined period of time

This is the process that scientists use to determine absolute age

Original Horizontality

Rocks that are on the bottom of a sequence are _______ than the rocks on the top of the sequence.

Older

Which layer is younger: A or B? Why?

B, because of intrusion
