Q

Why is the inner core solid but the outer core liquid?

A

Because of the immense pressure that the inner core receives exceeds the heat in the heat and pressure curve that determines the state of a solid liquid or gas

Q

What is the difference between extrusive and intrusive igneous rocks?

A

Intrusive igneous rocks cool below the ground as magma and extrusive igneous rocks cool above the surface after they have been deemed lava.

Q

Explain the process that creates a sedimentary rock

A

Little grains and molecules are weathered off the surface of an ordinary rock and carried away by agents of erosion such as snow ,water,wind and gravity and then taken to a place where they are compressed and compacted to form a sedimentary rock.

16
Q

What is a distinct feature of a extrusive igneous rock

A

Usually have little holes from the places where the bubbles were

17
Q

Why is color an unreliable way to distinguish minerals ?

A

Because certain rocks may occur in multiple colors and different rocks may be the same color

18
Q

How is hardness determined?

A

Using the mohs scale which determines hardness based on relative hardness to other substances

19
Q

What are the three other ways to identify minerals

A

cleavage(how a mineral fractures) lustre (how it shines earthy for not very shiny,vitreous for fairly metallic for very shiny) and density

20
Q

What is common in the crust?

A

Light Silicates

21
Q

Where would you find bridgemantite?

A

Lower Mantle

22
Q

What is a quality of all the layers?

A

The further down you go the density increases

23
Q

Where is ringwoodite commonly found?

A

Transition Zone

24
Q

What might you find in the upper mantle?

A

Olivine

25
Q

What can be found in the inner core?

A

Heavy metals and sulfides

26
Q

What can be found in the outer core?

A

No particular metal it is all liquid

27
Q

How would metals form the inner core reach the crust?

A

Initially those metals may rise through the outer core and find an opening in the mantle.These may be where tectonic plates have been smooched to make a volcano so that the sulfides etc. come out as igneous rocks
